车辆跟驰模型研究综述

An overview on car-following model

从模型形式、参数标定以及模型假设条件的角度出发,对相对速度—加减速度模型、安全距离模型、线性模型进行了综合论述,分析已有模型的特点及适用条件,认为目前的车辆跟驰模型由于其假设前提的限制,制约了其在交通流系统中的实际应用,说明有必要建立基于综合环境影响的车辆跟驰模型,并根据我国交通的实际特点加以运用。

GHR,collision avoidance and linear car- following model are discussed from model form,param- eter demarcation and model assumption.The charac- teristics and applicable conditions of these models are analyzed.It is concluded that current car- following models are restricted to put into practice of traffic flow system for the limitation of their assumption.There- fore,it is necessary that car-following model be es- tablished based on impaction of synthetic surroundings and applied according to traffic specialty in China.
