基于V2X的协作式车道预留系统设计与功能测试验证

Design and Functional Testing Verification of Collaborative Lane Reservation System Based on V2X

近年来,随着智能网联技术和设施建设的迅速发展,设计一种基于V2X的协作式车道预留系统,该系统主要包括车辆子系统和基础设施子系统,2个子系统利用V2X技术实现通信,车辆在进入预留车道前300 m或更远位置就可以发送车道预留请求,基础设施子系统收到请求后1s内生成车道预留策略和车辆驾驶引导信息并广播,给予预留车道上车辆充分时间调整自身行驶状态,确保优先车辆驶入预留车道后不受干扰。同时,设计3个测试项目在2个路段进行测试,所有项目均通过测试,证明协作式车道预留系统的合理性、有效性。

Intelligent networking technology and facility construction have developed rapidly over recent years.Based on this,a collaborative lane reservation system is proposed based on V2X,which mainly includes vehicle subsystems and infrastructure subsystems.The two subsystems use V2X technology to achieve communication.Vehicles can send lane reservation requests at a distance of 300 m or more before entering the reserved lane.The infrastructure subsystem generates lane reservation and vehicle guidance information within 1 second of receiving the request and broadcasts it,giving vehicles on the reserved lane sufficient time to adjust their driving status and ensure that priority vehicles are not disturbed when entering the reserved lane.Finally,three testing projects are designed to be tested on two road sections,and all projects passed the tests,proving the rationality and effectiveness of the collaborative lane reservation system.
