摘要：

为揭示信号倒计时对驾驶决策行为的影响，本文基于实测数据对信号控制进口道各断面的车速分布特征进行了分析，研究发现临近停车线处于不同断面位置的车辆行驶特性由于信号倒计时的有无及剩余绿灯时间的影响而存在差异.提出了考虑信号倒计时下驾驶心理的元胞自动机模型，通过数值模拟剖析了不同时空条件(位置、车速与剩余时间)下微观驾驶心理与行为对中观交通流的作用机理.结果表明，该模型可较好地刻画信号灯控制下城市进口道路车辆运行特性.

Abstract:

In order to reveal effects of a signal counting- down on driving decision making, the paper analyzes characteristics of vehicle speed distribution on different cross sections of entrance lanes with signal control based on measured data. Research results show that characteristics of vehicle running at different cross sections near the stop line are different due to effects of with or without signal countdown and residual green time. The paper proposes a cellular automation model of driving mentality with consideration of signal counting- down and analyzes the action mechanism of microscopic driving mentality and behavioral responses on mesoscopic traffic flow under different time- space conditions (position, vehicle speed and residual time). Results show that characteristics of vehicle running on urban entrance roads under signal lamp control could be described by the model effectively.

Key words: urban traffic, cellular automata, simulation, signal control intersection, countdown
