Analysis of Urban Public Transportation Intelligence and Key Research and Development Directions


Recently, the relevant leaders of the Ministry of Industry and Information Technology and the Ministry of Science and Technology have repeatedly stated on different occasions that priority should be given to the issue of urban public transport intelligence so that it can generate economic and social benefits. It can be seen that urban public transport is an important window for public transportation, and its intelligent transformation and development is particularly important. With the deepening of the understanding and expectation of intelligent transportation in the society, the intelligentization of urban public transportation is promising. The market capacity is considerable, and both social and economic benefits will be achieved. However, it is necessary to grasp the key areas and development directions of urban public transportation intelligence.

The status quo of urban public transport intelligent development. The intelligentization of urban public transportation is the need of operation and management when the public transportation reaches a certain scale, and it is also the need of the entire traffic informationization. Generally speaking, the intelligent public transportation system is composed of a dispatch management system, an electronic stop sign system, an in-vehicle terminal system, an information release system, a vehicle technical information management system, a parking lot management system, and the like, and a signal priority system.9.142

The characteristics of urban public transport intelligent development. 

First, the gap between the development speed of big cities and small and medium-sized cities is small. Large cities and small and medium-sized cities are developing at similar speeds. In some medium-sized cities, development is faster. For large cities, the traffic pressure is greater, and the difficulties faced by public transport are far greater than those of medium-sized cities.

Second, higher integration and smarter systems are the main trends in the future. Specifically, the intelligent dispatching system has more comprehensive functions, and the scope of intelligent dispatching is more extensive. The functions of personnel, vehicle technology, line, geographic information, operation scheduling, finance, maintenance, management analysis, video monitoring, and vehicle condition monitoring are more detailed. The functional interaction between the systems is closer to the actual application needs of the bus industry and solves practical problems.

Third, there is no single market structure. There is no monopolistic enterprise in the smart bus market, and there is not a single market structure. It is still in the status quo of the market share of various manufacturers.

Fourth, technology is the most critical factor in the development of the industry. Technology is the key to truly driving the development of the entire intelligent transportation industry. Otherwise, even if there is funds, a perfect bus operation system cannot be realized, and the goal of strengthening the command and dispatch of operating vehicles and improving operational efficiency cannot be achieved.

Urban bus intelligent key research and development direction.

First, the key technologies for the intelligentization of transportation informationization. Transportation infrastructure data collection based on next-generation information technology, high-speed data access, industry information resources open sharing and big data basic analysis platform, industry cloud platform, Internet of Things construction and interconnection, high-precision 3D traffic GIS construction, industry network And information security, monitoring and early warning and emergency response.

Second, key technologies for traffic operations management. New generation traffic control network operation organization and evaluation, comprehensive traffic dynamic monitoring and early warning based on big data, road traffic conflict warning and active collision avoidance based on vehicle road cooperation, precise positioning and traffic organization based on Beidou satellite navigation technology, based on High-speed Earth observation data for transportation infrastructure inspection, real-time monitoring and emergency assistance decision support for transportation vehicles and cargo, traffic card mobile payment, smart traffic based on cloud computing and big data.

Third, the key technologies of transportation information services. Based on cloud computing and mobile Internet, government-enterprise cooperation integrated traffic travel information service, Internet-based freight industry operation monitoring and service supervision, logistics big data collection and processing and forecast analysis, mobile Internet-based freight logistics integrated transportation information service, convenient transportation electronics Port key technologies, intelligent and interoperable vehicles in the mobile Internet environment, free flow charges for road networks.

Fourth, the "Internet +" efficient logistics key technology. Key technologies for efficient matching and efficiency improvement of people, vehicles and goods flow resources, key technologies for innovation of freight logistics organization model based on mobile Internet, key technologies for interconnection and communication of logistics resources based on Internet of Vehicles, and freight logistics market based on mobile Internet and big data technology Supervision of key technologies, freight hub node regional connection and transfer coordination organization model optimization, urban and rural logistics distribution organization kimono.
