Multi-tag Information Interactive Communication Model based on Precise Position Detection in Vehicle-Infrastructure Collaboration Environment

The traditional GPS exits the large location error and the issues unable to verify the precision of location information considering the adaptation to the urban complex traffic environment. An information interaction model based on multiple groups of RFID tags is proposed, which can realize the real-time precise position detection by integrating the location, CAN message, tag distance and other information. Based on the multi-tag information detection system, a multi-tag information interactive communication GCD (i.e., the GPS location, CAN message, tag distance) model is designed. Meanwhile, a multi-dimensional GCD model is proposed, which adapts to the multi-dimensional space-time characteristics of the urban complex traffic environment. A case study of the proposed GCD model is carried out by taking dual-source trolleybus charge and bus priority control as examples. The results show that based on the proposed GCD model, the charging design can theoretically increase 36% of each bus capacity in a single day, The operating speed in the past four years is increased from 13.5km/h before construction to about 19.36km/h.
