客货分离道路系统的车辆分类标准和评价方法

Vehicle classification and evaluation method of separating trucks from passenger vehicles

提出一种适用于客货分离道路系统的客货车辆分类法,仿真验证表明,其与传统车辆分类法相比,在客货分离道路上采用该分类法具有优势,为实施高速公路客货分离改造提供了有依据的车辆分类标准.通过比较平均车速、延误、车速离散系数和换道次数等指标,评价高速公路客货分离改造效果的方法,为客货分离道路系统的评价研究提供了思路.

A vehicle classification for separating trucks from passenger vehicles is presented. The advantages of the method are verified by simulation experiments in comparison with the traditional classification of freeways, and a scientific basis for vehicle classification criteria is provided. A method for evaluating the system of separating trucks and passenger vehicles by comparing the indicators of average speed, delay, speed dispersion coefficient and lane changing time is proposed. The method might provide an idea for evaluation of the system of separating trucks and passenger vehicles.
