车路协同环境下紧急车辆优先通行控制策略

摘要

车路协同技术的快速发展为紧急车辆（如消防车、救护车等）在城市道路中的高效优先通行提供了新的可能。本文围绕紧急车辆在智能交通环境下的优先控制问题，提出一套融合道路感知、车辆动态信息和信号控制策略的整体框架，旨在提升紧急响应效率并减少对常规交通流的干扰。通过构建车路协同的通信与感知系统，实现对紧急车辆位置、速度和路径的实时监控与预测，结合动态信号配时算法，对沿线交叉口进行智能优化控制。模拟实验验证该策略在提高紧急车辆通行效率、保障行车安全性及优化交通整体运行方面具有显著优势，为未来智慧交通调度系统的构建提供理论基础与实践路径。

Abstract

The rapid development of Vehicle-Infrastructure Cooperation (V2I) technology has opened up new possibilities for emergency vehicles (such as fire trucks, ambulances, etc.) to achieve efficient and priority passage on urban roads. Focusing on the priority control issue of emergency vehicles in an intelligent transportation environment, this paper proposes an integrated framework that combines road perception, real-time vehicle dynamic information, and signal control strategies. The aim is to enhance emergency response efficiency while minimizing interference with regular traffic flow. By establishing a V2I-based communication and perception system, real-time monitoring and prediction of the emergency vehicle's position, speed, and route are realized. Combined with a dynamic signal timing algorithm, intelligent optimal control is applied to the intersections along the emergency vehicle's path. Simulation experiments have verified that this strategy exhibits significant advantages in improving the passage efficiency of emergency vehicles, ensuring driving safety, and optimizing the overall traffic operation. It provides a theoretical foundation and practical path for the construction of future intelligent traffic dispatching systems.
