On May 25, 2021, the 2020 Shanghai Science and Technology Award was announced. The scientific and technological workers who have made outstanding contributions to the cause of science and technology and the modernization of Shanghai were solemnly commended. Professor Wanjing Ma presided over and completed the "Key Technology and Application of Precision Service and Efficient Management and Control of Urban Public Transportation"and won the first prize of the 2020 Shanghai Science and Technology Award.

The project is led by Shanghai Dianke Intelligent System Co., Ltd. and jointly participated by Tongji University, Shanghai Institute of Urban Rural Construction and Transportation Development, Sciences Academy of Ministry of Transport, Shanghai Jiushi Public Transport Group Co.,Ltd., Shanghai Municipal Engineering Design and Research Institute (Group) Co.,Ltd. and Shanghai Transportation Development Research Center.

China has the most complex and huge ground bus system in the world, serving 120 million people every day, which is the basic support for the basic travel of urban residents and the normal operation of urban functions. However, the problems of weak matching between supply and demand, poor reliability and low operation efficiency of the ground bus system are prominent. Improving the intelligent level of service and operation management is a source and sustainable scientific governance way. However,there is a lack of systematic research results applicable to the characteristics of large cities in China, such as wide distribution of public transport demand,high passenger flow intensity, complex network, and shortage of road resources.

With the continuous support of the National 863 program and the natural science foundation, the project has gone through 12 years of joint research by industry, university and research. Facing the four levels of "demand identification, network optimization, scheduling management and operation control", the project has proposed the technology of accurate tracing and trip portrait of public transport passenger flow,established the technology and system of data-driven automatic diagnosis and network optimization of public transport service. The project established the system of data-driven automatic diagnosis and network optimization. It has formed the technology and system of bus operation state prediction and intelligent scheduling. The technology and equipment of bus priority collaborative management and control have been invented. The project systematically conquered the ground bus intelligent set of technology, system and equipment with accurate service and efficient management and control as the core.
