一种确定加速车道长度的概率统计模型

A Probability Model for Length of Acceleration Lanes on Expressway

加速车道有利于次要道路上的车流平顺地汇入高速公路的车流 ,加速车道长度的确定是加速车道设计的核心内容。本文针对加速车道车流的运行特性 ,从概率统计角度研究了加速车道上车辆汇入高速公路车流的概率 。

Acceleration lanes are important to freeway and the length identification is the core of its design.This paper studies the operation characteristics and the merging process of vehicles on acceleration lanes.As a result,a probability model is proposed for the length identification of freeway acceleration lanes.
