Urban traffic problems have become one of the most pressing challenges in modern society, especially in densely populated urban areas. As cities grow and vehicle ownership increases, traffic congestion, pollution, and inefficiencies in transportation systems have reached critical levels. In response, intelligent transportation systems (ITS) are being recognized as a powerful solution to these growing issues. By integrating advanced technologies such as data communication, information processing, and electronic control, ITS aims to create a more efficient, safe, and sustainable transportation environment.
Intelligent transportation systems are now an essential part of the global transportation industry's evolution. Over the years, significant investments have been made by both governments and private sectors around the world to develop and implement these systems. China has also made considerable progress in this field, with the development of advanced traffic management systems and public transport solutions that have matured over time. These systems play a vital role in easing traffic pressure in large and medium-sized cities, improving mobility, and reducing environmental impact.
**First, the current status of intelligent transportation development**
Intelligent Transportation Systems (ITS) represent a high-tech research area focused on optimizing human, material, and financial resources across countries. Japan, the United States, and Europe are the leading centers for ITS research. In the 1970s, Japan pioneered comprehensive traffic control systems and became one of the earliest adopters of ITS technology. The country implemented nationwide ITS applications, including the deployment of millions of car navigation devices, significantly enhancing traffic efficiency and service quality.
In the U.S., the ITS initiative began later but quickly gained momentum. Starting in 1991, the U.S. government invested heavily in ITS research, launching over 100 projects within four years and establishing dedicated research organizations. By 1997, the U.S. had allocated $700 million to ITS, followed by the passage of the "Transportation Equity Act of the 21st Century," which further boosted funding for transportation innovation.
Europe took a collaborative approach, with governments, businesses, and individuals jointly supporting ITS research. One of the most notable projects is the DRIVE program, involving 12 countries and over 700 companies, with a total investment of 500 million euros. This project highlights the region’s commitment to advancing smart mobility solutions.
China entered the ITS field relatively late, beginning focused research in the 1980s. Many cities introduced foreign traffic control systems, while the government also invested in domestic R&D. Notable examples include the SUATS system developed by Shanghai Jiaotong University and the HT-UTCS real-time adaptive traffic control system. In 1998, the Ministry of Communications established the ISO/TC204 China Committee to develop standard frameworks for ITS, promoting its widespread application across hundreds of cities.
ITS is a multidisciplinary system that integrates information technology, data communication, electronic sensing, and computer processing. Its goal is to provide real-time, accurate, and efficient transportation management. Initially proposed in the U.S. in the 1960s, ITS has since evolved into one of the most advanced technological fields, following aerospace and military sectors. It plays a crucial role in reducing accidents, congestion, and pollution, while also boosting economic growth through increased efficiency and job creation.
**Second, the significance of building intelligent transportation systems**
Transportation is a cornerstone of economic development, yet traffic congestion and pollution have become major global concerns. Poor traffic flow leads to increased emissions, reduced air quality, and economic losses. To address these issues, investing in intelligent transportation systems is essential. Compared to other modes, road transportation offers directness, flexibility, and speed, making it the primary choice for short-distance travel between cities.
The integration of computer, communication, and GPS/GIS technologies can enhance highway infrastructure, improve traffic efficiency, and reduce failures. Intelligent transportation not only optimizes resource use but also supports sustainable development by lowering fuel consumption and emissions.
With increasing attention from local governments, many cities have achieved high levels of intelligent traffic management. Services like ETC tolling, parking guidance, and real-time road updates are now widely available. Looking ahead, China’s intelligent transportation will follow six key trends: dynamic perception, on-demand information services, proactive safety alerts, information sharing, green development, and market-driven innovation.
**Third, countermeasures for the development of China’s intelligent transportation system**
Despite some gaps compared to developed countries, China’s transportation sector continues to advance steadily. Passenger and freight volumes have grown significantly, and various transport modes have improved. However, to fully realize the potential of ITS, several steps need to be taken.
First, there should be more focus on basic theoretical research, along with international collaboration to ensure China keeps pace with global developments. Second, a coordinated organization similar to ITSAmerica or ERTICO should be established to unify standards and strategies. Third, talent development must be prioritized, with enhanced education and training programs to meet future demands. Finally, specific projects should be selected based on China’s unique conditions, such as standardization, public transport systems, and logistics.
In conclusion, as the economy grows, intelligent transportation systems are becoming a key driver for solving urban mobility challenges. With continued investment and innovation, China can position itself as a leader in this rapidly evolving field.
