基于SUMO的虚拟交通灯的设计与实现

Design and Implementation of Virtual Traffic Light Based on SUMO

摘要: 现行的传统物理交通信号灯存在着不能很好适应复杂的交通情况和高额的维护费用等弊端，一种解决方法是采取虚拟交通灯方案，依托车联网技术，通过车车交互来选择领导车辆，并由领导车辆承担传统交通灯的工作，负责绿灯通行权的授予和回收。本文基于SUMO (Simulation of Urban Mobility)搭建了虚拟交通灯平台，设计了虚拟交通灯平台的车辆状态、消息格式以及核心控制算法。通过在平台上实现传统的交通灯与虚拟交通灯进行比较实验，证明虚拟交通灯相较于传统物理交通灯模式性能上有很大的提升。本文搭建的基于SUMO的虚拟交通灯平台可以为今后的深入实验和研究提供平台和框架。

Abstract: The traditional physical traffic lights do not work well with the complex traffic situation and need high maintenance costs. One solution is virtual traffic lights which rely on vehicle network. Leader vehicle is selected through the vehicle interaction, and the leader vehicle takes responsibility of traditional traffic lights to grant and revoke green light. This paper builds a virtual traffic lights platform based on SUMO (Simulation of Urban Mobility), and designs the vehicle status, message format and core control algorithm of the virtual traffic lights. The experiment proves that the performance of virtual traffic lights is greatly improved compared with the traditional traffic lights on the platform. The SUMO-based virtual traffic light built in this paper can provide a platform and framework for future indepth experiments and research.
