Cooperative Perception Message Transmission Control Scheme Based on Information Value
摘要
Abstract
Roadside Units(RSU)detect and sense the road environment to form a Cooperative Perception Message(CPM),and this CPM is transmitted from the RSU to vehicles on a road.This process can expand the sensing range of vehicles and effectively improve the safety index of vehicle traveling.However,in urban scenarios with many vehicles and pedestrians,the volume of CPM data generated by an RSU after sensing road objects(including vehicles and pedestrians)is excessive,including a large amount of Perceived Object Information(POI)with low safety value.Sharing them frequently with vehicles is likely to congest networks,thereby increasing transmission delay and reducing the quality of service of the CPM.To address this issue,this paper proposes a CPM transmission control scheme called TRAC,which identifies the collision risk of road objects through Improved Time-to-Collison(Improved-TTC)to determine the traffic safety value of the POI.The RSU uses this value to selectively transmit the POI.The adaptive CPM transmission control algorithm in TRAC determines the CPM generation frequency based on the real-time network state.The CPM high-value transmission content selection algorithm determines which POI should be transmitted based on traffic safety values.This scheme effectively reduces transmission delays and improves the quality of service of the CPM.Compared with existing schemes,the CPM transmission delay of TRAC scheme is increased by up to 89％,and the quality of service of the CPM is increased by up to 8.1 times.关键词
