With the growing urban areas, China is currently encountering aggravated traffic congestion due to rapidly accelerating motorization. This has led to increased CO2 emissions and other forms of environmental pollution, causing serious concern throughout society. To solve these problems, improving the convenience of public transportation and promoting the use, thereby regulating the number of vehicles on the road is expected as one of the effective measures.
The purpose of this joint development is to combine Sumitomo Electric’s traffic control technologies and Tongji University’s bus priority control technologies, thereby facilitating research and development of a traffic control system to support the smooth flow of public buses, for which the need is growing in China. This system controls traffic signals in response to a traffic situation through a signal controller and vehicle detectors installed at an intersection. Additionally, approaching buses are detected by wireless equipment, and the timing of green lights or red lights are controlled for the buses to cross intersections smoothly.
A field test is planned to commence in October on a public road in Taicang, Jiangsu, China in order to confirm the effects of the signal control and bus priority driving. The joint development is scheduled to be continued until the end of March 2014. Release of the system will be considered based on the progress of the development.
We will continue to provide traffic solutions to prevent traffic accidents and mitigate congestion with the aim of contributing to the sustainable development of global society.
