Editor's note:

With the acceleration of urbanization, the population and functional density of cities continue to rise. As the "lifeblood" and "nerve" that maintain the normal operation of cities, urban lifeline engineering has become a core issue in enhancing urban resilience through its safety guarantee. This type of system, which covers key infrastructure such as water supply, power supply, transportation, and communication, is highly interconnected and inherently fragile. Once it is impacted by disasters or accidents, it is highly likely to cause chain paralysis, directly threatening the safety of people's lives and property and social stability.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

Sichuan Shengtuo Testing Technology Co., Ltd., as a leading enterprise in this field, has developed multiple world first non-destructive testing projects for engineering structures with shock elastic wave technology as its core, achieving international leading levels. The founder and chairman of the company, Wu Jiaye, is a Ph.D. from Tsinghua University and a well-known expert in the field of non-destructive testing in China. In his early years, he went to Japan to further his studies in engineering testing and intelligent construction and maintenance technology. In 2007, he returned to China with "shock elastic wave technology" to start a business. Through years of practice, he built a non-destructive testing technology system for structures such as concrete and geotechnical engineering; In recent years, there has been a greater focus on intelligent terminals, robots, the Internet of Things, and artificial intelligence technologies, forming a comprehensive solution of "smart construction, detection, and monitoring" that covers the entire life cycle of engineering.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

In this issue of Qingqiao International Journal's "Ningdian Interview" column, we have a special conversation with Chairman Wu Jiaye to explore the development of non-destructive testing technology and the security code of urban lifeline engineering.

As one of the first direct doctoral students at Tsinghua University, what was your initial intention to shift from academic research to entrepreneurship in the field of engineering testing?

Wu Jiaye:

Firstly, I yearn to return to my home country. During my overseas studies, I always cared about the development of my country, and returning to participate in national construction was an instinctive choice. On the other hand, although our industry has a solid theoretical system and profound academic accumulation, it fundamentally relies heavily on practical applications. As an applied field, only by truly delving into the industry and promoting the implementation of technology can its value be realized. Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.What were the main difficulties you and your team encountered in the early stages of establishment, and how did you overcome them?

This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

The conditions in the early stages of entrepreneurship are indeed very difficult. When we entered the testing industry twenty years ago, we faced an almost blank market. At that time, society's understanding of the testing industry was still in its infancy, and the most common question customers asked was, "Can you measure accurately? Why should we trust you?" They had to face such questions almost every day.

Firstly, I yearn to return to my home country.

As an applied field, only by truly delving into the industry and promoting the implementation of technology can its value be realized. Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.There are also obvious shortcomings in terms of hardware. Due to the limited level of electronic and computer technology at that time, detection equipment was generally bulky and had poor portability, which had a significant gap with the actual market demand. What's even more difficult is that the team lacks marketing experience and has very limited funds. Directly replicating foreign models has repeatedly encountered obstacles, and localization transformation is urgent.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

There is no shortcut to breaking through difficulties, only through technological innovation. We choose to focus on industry pain points and continuously invest in research and development in areas where others cannot do well or excel. The turning point occurred around 2012. At that time, the problem of cutting corners and materials frequently occurred in the construction of highway protective columns, and traditional methods were unable to detect the buried parts underground, posing great safety hazards. Our non-destructive testing technology has successfully solved this problem, not only accurately obtaining parameters of underground structures, but also promoting the inclusion of this technology in national standards. This breakthrough not only validates our technological capabilities, but also demonstrates the practical value of detection technology to the entire industry.

This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

Technological breakthroughs have brought about chain effects far beyond expectations. With the adoption of national standards, market awareness has undergone a fundamental shift from "why testing is necessary" to "how testing is better". The portability process of devices has also greatly accelerated, and advances in computer technology have made instruments smaller and more intelligent, significantly improving on-site detection efficiency. Marketing strategies have gradually shifted from rigid promotion to establishing professional reputation through the development of technical standards and sharing of typical cases.

As a founder, how did you position and plan for technology research and market expansion in the early stages of entrepreneurship?

Since the establishment of the company, our positioning and planning have been dynamically adjusted, but the core has always revolved around the real needs of the industry. Initially limited by qualification barriers and market awareness, we chose to start with testing services and establish customer trust by obtaining professional qualifications. The core of this stage is to address the issue of 'how to be recognized'.

Firstly, I yearn to return to my home country.

On the other hand, although our industry has a solid theoretical system and profound academic accumulation, it fundamentally relies heavily on practical applications.

Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.With the accumulation of technology and deepening understanding of the industry, we are gradually shifting towards the positioning of technology service providers. We realize that providing testing services alone is difficult to form differentiated competitiveness, and we must enhance service value through technological innovation. For example, the non-destructive detection technology developed in the detection of highway pillars not only solves the blind spot problem of traditional detection, but also promotes the establishment of industry standards, laying the foundation for subsequent transformation.

After reaching a certain scale of technical reserves, we further extend to software development and system integration. The key to this stage is to break through the single role of equipment suppliers and develop digital tools such as smart construction site management systems and engineering health monitoring platforms to transform detection data into decision-making basis that can guide production. For example, combining real-time monitoring data with BIM models to achieve dynamic optimization of the construction process.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

At present, we are evolving towards an engineering big data platform, committed to integrating multiple sources of data such as detection, monitoring, and maintenance, and building a digital twin system that covers the entire lifecycle of engineering. This upgrade is not simply business expansion, but based on the judgment of the industry's digital transformation trend - when a single point of technological breakthrough forms a demonstration effect, systematic solutions will become a new value growth point.

In recent years, "urban lifeline" has become a hot topic in urban safety. What do you think are its core pain points?

“城市生命线”近年来成为城市安全热点，您认为其核心痛点是什么？

Firstly, I yearn to return to my home country. During my overseas studies, I always cared about the development of my country, and returning to participate in national construction was an instinctive choice. On the other hand, although our industry has a solid theoretical system and profound academic accumulation, it fundamentally relies heavily on practical applications. As an applied field, only by truly delving into the industry and promoting the implementation of technology can its value be realized. Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.The essence of "urban lifeline" is the fundamental support system for urban operation. In the process of global urbanization, it is a common trend for the population to concentrate highly in big cities. For example, Seoul accounts for nearly half of the population in South Korea, and the population proportion of Japan's three major metropolitan areas exceeds30%This high degree of agglomeration places extremely high demands on the stable supply of infrastructure. Linear engineering facilities such as water, electricity, gas, communication, and transportation are like the "blood vessels" and "nerves" of a city, and their safe operation directly affects people's daily lives and even life safety.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

The larger the city size and the denser the population, the more prominent the vulnerability of the lifeline system becomes. Once encountering extreme weather, geological disasters, or human accidents, system damage may lead to the paralysis of urban functions, causing far greater losses than usual. This characteristic determines that its security must become the core link of urban planning, construction, operation, and emergency management.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

I think its core pain points are mainly reflected in three aspects: first, continuous operating pressure. The system needs to maintain 24-hour uninterrupted operation, and any minor malfunction may trigger a chain reaction, requiring extremely high timeliness for monitoring and maintenance. The second reason is the concealment, which makes maintenance difficult. A large number of pipelines are buried underground or hidden inside buildings, and traditional manual inspections are difficult to fully cover. Safety assessments have long been plagued by the problem of "invisible and inaccurate". Thirdly, there are cognitive constraints on safety investment. Due to the sporadic nature of accidents, the high cost of daily maintenance is easily overlooked, leading to a common mentality of "emphasizing remedial measures after the fact and neglecting preventive measures before the fact", further exacerbating system risks.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

To solve the problem of urban lifeline security, efforts need to be made in both technological upgrading and management innovation - early detection of hidden dangers through intelligent monitoring, optimization of maintenance strategies through big data, and promotion of the value consensus of "preventive security" throughout society, in order to build a more resilient urban security system.

What are the challenges facing the upgrading of urban lifeline engineering system from traditional detection to intelligent terminal, robot, and AI collaborative monitoring system?

Firstly, I yearn to return to my home country. During my overseas studies, I always cared about the development of my country, and returning to participate in national construction was an instinctive choice. On the other hand, although our industry has a solid theoretical system and profound academic accumulation, it fundamentally relies heavily on practical applications. As an applied field, only by truly delving into the industry and promoting the implementation of technology can its value be realized. Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.Currently, many cities, especially large ones, are paying increasing attention to the safety of lifeline engineering and are actively promoting the construction of various safety management and monitoring systems. I strongly agree with the security monitoring technology roadmap based on the Internet of Things - with the continuous advancement of communication and sensor technology, the monitoring range continues to expand and the accuracy is significantly improving. But in this process, we also face some urgent challenges that need to be addressed.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

The first and foremost challenge is the balance between cost and benefit. The initial construction requires the installation of a large number of sensors to achieve full coverage, but the limited monitoring range of a single point leads to an exponential increase in equipment quantity and cost. Continuous investment is needed for later operation and maintenance, and sensors are on averagefiveThe annual lifespan means high costs for periodic replacement and debugging, while faulty sensors may transmit false data, and data calibration and verification further drive up overall expenses. This contradiction of 'being able to build but unable to maintain' constrains the large-scale implementation of monitoring networks.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

Secondly, the existing technological system has natural blind spots. Sensors rely on preset points to collect data, making it difficult to detect safety hazards in uncovered areas through conventional means. For example, in a building fire last year, the fire doors were unable to open due to mechanical failure, resulting in increased casualties. The abnormal state of these non electronic facilities makes it difficult for traditional sensors to capture in real time, exposing the limitations of relying solely on IoT monitoring.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

The deeper challenge lies in the lack of technological collaboration. Although 5G communication and sensing technology have improved data collection capabilities, multi-source data fusion analysis is still weak: robot inspection images, AI recognition results, sensor environmental parameters, etc. have not yet formed effective linkage. This phenomenon of "data silos" limits the accuracy of early warning and makes it difficult to support rapid decision-making.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

It must be pointed out that monitoring methods centered around sensors are an important direction for improving safety, but relying solely on this approach is far from enough. We also need to combine other technological means to build a more three-dimensional risk prevention and control system. This is also a crucial but easily overlooked aspect in the current construction of urban lifelines.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

Therefore, building an intelligent monitoring system cannot stop at laying sensor networks, but also needs to simultaneously break through three major bottlenecks: extending sensor life through material innovation, developing self calibration technology to reduce maintenance costs; Combining robot inspection and AI image recognition to fill monitoring blind spots; Establish a unified data platform to achieve multimodal information fusion analysis. Only by simultaneously upgrading technology and innovating management can we truly build a resilient defense line for the lifeline of the city.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

From a global perspective, what level of technology is China's urban lifeline engineering in?

Firstly, I yearn to return to my home country. During my overseas studies, I always cared about the development of my country, and returning to participate in national construction was an instinctive choice. On the other hand, although our industry has a solid theoretical system and profound academic accumulation, it fundamentally relies heavily on practical applications. As an applied field, only by truly delving into the industry and promoting the implementation of technology can its value be realized. Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.From a global perspective, urban lifeline engineering technology centered around monitoring systems mainly includes three directions: Internet of Things technology, data storage and analysis technology, and data-driven institutional and decision support. In terms of technological capabilities, China is in the top tier globally in urban lifeline safety monitoring.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

This can be seen from two aspects: the Internet of Things and big data analysis. The Internet of Things includes sensing technology, data acquisition and transmission technology. In terms of sensors, there is no significant gap between China's technological level and the international advanced level, and some fields are still relatively leading. In terms of data collection and transmission, China's 5G communication technology has a global leading advantage. However, some high-end chips used in the Internet of Things, such as high-speed processing chips, still have a gap compared to top technologies such as those in the United States, and currently rely heavily on imports. But overall, excluding a few high-end chips, China's overall strength in IoT technology is in the world's top tier.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

At the level of big data analysis and application, China has demonstrated significant advantages in database construction, AI algorithm optimization, and other aspects. By using deep learning algorithms to analyze monitoring data, accurate identification of abnormal events such as pipeline leaks and bridge deformations has been achieved, and the early warning accuracy in some pilot projects in cities has reached the international leading level.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

In terms of technological application mode, China has formed a characteristic path of "human-machine collaboration". Although the traditional mode of relying entirely on manual inspection is still continuing, the popularity of handheld intelligent terminals has significantly improved efficiency - operation and maintenance personnel complete the entire process of data collection, anomaly tagging, location reporting, etc. through terminal devices, combined with backend algorithm analysis, to build a closed-loop management system covering "monitoring warning disposal". This progressive technology integration strategy is not only in line with current management practices, but also lays the foundation for future comprehensive intelligent transformation.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

Overall, the life of Chinese citiesThe online technology system has achieved a leap from following to running simultaneously, but breakthroughs are still needed in key areas such as chip localization and data fusion analysis. Through continuous technological iteration and model innovation, it is expected to form a global leading advantage in the field of intelligent monitoring.

Is the application of "urban lifeline" related technologies more valuable in the frequent occurrence of engineering accidents in karst landform areas such as Southeast Asia?

Firstly, I yearn to return to my home country. During my overseas studies, I always cared about the development of my country, and returning to participate in national construction was an instinctive choice. On the other hand, although our industry has a solid theoretical system and profound academic accumulation, it fundamentally relies heavily on practical applications. As an applied field, only by truly delving into the industry and promoting the implementation of technology can its value be realized. Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.The frequent occurrence of engineering accidents in the karst landform areas of Southeast Asia highlights the special value of the application of "urban lifeline" technology. Except for Singapore, most countries in the region are in the stage of accelerated urbanization, and the safety reserve of urban construction is generally insufficient. Due to the lack of sufficient institutional and economic support in the early planning and construction, the safety redundancy is low, resulting in a significant increase in the risk of engineering accidents.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

In this context, the collaborative model of "monitoring+inspection" advocated by China is more adaptable. Southeast Asia has relatively low labor costs and a high penetration rate of mobile phones. Empowering manual inspections through smart terminals can not only reduce the high cost of full IoT monitoring, but also rely on mobile networks to achieve real-time data transmission. This "lightweight" technology path is more in line with the needs of the local development stage.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

The deeper value lies in the optimization space of the quality management system. Southeast Asia often adopts the European and American contract model of first party and second party, but the technical consulting and third-party testing links are weak, resulting in the acceptance of building quality being merely a formality. The numerous cases of substandard buildings in the Bangkok earthquake indicate a regulatory blind spot due to the lack of independent testing agencies, which poses significant safety hazards for later operations. The multiple testing mechanisms established by China (self inspection by construction parties, random inspection by supervisors, third-party acceptance, etc.) can precisely fill this gap.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

Therefore, exporting China's mature "urban lifeline" technology system and quality management model to Southeast Asia can not only enhance accident prevention capabilities through intelligent monitoring, but also control engineering quality from the source through improved detection processes, forming a safety loop covering the entire construction and operation cycle. This has significant reference significance for regions with complex geological conditions and similar development stages.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

With the advancement of the "urban lifeline", which new areas do you think the lifeline project will extend to? Where could be the next breakthrough point?

Firstly, I yearn to return to my home country. During my overseas studies, I always cared about the development of my country, and returning to participate in national construction was an instinctive choice. On the other hand, although our industry has a solid theoretical system and profound academic accumulation, it fundamentally relies heavily on practical applications. As an applied field, only by truly delving into the industry and promoting the implementation of technology can its value be realized. Based on this understanding, I believe that entrepreneurship can enable me to integrate more closely with the industry, allowing theory to constantly iterate and upgrade in practice.With the continuous promotion of the "urban lifeline" safety project, its coverage is gradually breaking through traditional basic fields such as gas, water supply, bridges, and drainage, and constantly extending towards new directions that are closer to people's livelihoods and more focused on prevention. Currently, engineering safety monitoring has been further expanded to include gas end-users, as well as monitoring the structure of public buildings such as schools and hospitals. With the help of intelligent sensing and prediction models, the level of urban drainage and flood prevention and sponge city construction has been significantly improved. In addition, many regions are actively laying out new application scenarios such as rail transit operation safety, elevator operation status monitoring, and intelligent fire safety systems.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

In the future, breakthroughs in urban lifeline engineering will rely more on technological integration and mechanism innovation. At the technical level, cutting-edge technologies such as digital twins, artificial intelligence, and 5G-A sensing integration will be deeply integrated to promote the transition from "passive disposal" to "active prevention and control". For example, by building a City Information Model (CIM) platform, integrating data resources from multiple departments, breaking down "information silos", and forming a cross departmental, full process collaborative governance mechanism. In the construction and operation mode, more attention will be paid to the flexible design of "dual-use of emergency and emergency", to enhance the resilience and recovery ability of infrastructure in disaster scenarios.

In this context, non-destructive testing technology, with its unique advantages of "non-destructive and precise measurement", has gradually become a key technical support for ensuring the safety of engineering structures. This technology detects internal defects in materials through non-invasive methods and has been widely used in industrial quality control and facility health monitoring, providing a scientific basis for extending equipment life and preventing accidents.

In short, urban lifeline engineering is moving from traditional physical infrastructure monitoring to a new stage of intelligent resilience with global perception, intelligent warning, and precise regulation. Its future development is not only related to technological iteration, but also relies on data connectivity, business collaboration, and institutional innovation. The ultimate goal is to build a safer, more efficient, and resilient modern urban operation system.
