Research on highway CPS-T of wide area communication and data cloud.
International Conference on High Performance Compilation, Computing and Communications (HP3C)(2022)
Abstract
Cyber physical transportation system (CPS-T) is a traffic perception, control and service system based on algorithm, model, data and computing power. With the help of radar point cloud, video image, GNSS, sensor and other types of monitoring equipment, the highway data can be collected with high quality and transmitted with high reliability under the condition of relatively complete communication conditions. This paper studies the technical application of CPS-T for highways. Through the deployment of communication technology and data cloud platform, it can intelligently perceive and analyze dynamic and static operation data, accurately identify or predict key ramps, bottleneck sections and mainstream traffic channels, and dynamically implement active control strategies such as ramp control, shoulder control, lane control and rate adjustment, so as to realize the advance guidance and control of highway traffic flow. The relevant research has been measured in the highway sections of Shanghai and Zhejiang Province, and the research results have strong engineering reference value.
