主观拥堵感知下驾驶人路径调整行为决策研究

为深入调查研究交通拥挤的形成机制和扩散规律,本文针对交通拥堵形成和消散的内因,即驾驶人在拥挤状态下路径的研判调整行为进行研究.设计基于全方位视角场景的驾驶人主观拥堵感知实验,通过采集驾驶人个体特征、出行特征和交通流参数,结合驾驶人的主观拥堵评分和路径调整决策,采用方差分析方法,探究驾驶人个体特征和出行特征对路径调整决策...

Route Adjustment Behavior Decision-making Based on Driver's Congestion Perception

To further understand the formation mechanism and diffusion law of traffic congestion, this paperinvestigates drivers' route finding and adjusting behaviors in traffic congestions. The driver's perception on congestionswas defined from experiments based on the omni-directional scene. By collecting the driver's individual characteristics,travel characteristics, and the traffic flow parameters, this study uses the variance analysis to examine the impact ofdrivers' individual characteristic and travel characteristics on driving route decision making. The Binomial Logistic isused to establish a route adjustment behavior model with driver's perceptions on congestions to further quantify thecorrelation between driver characteristics and route adjustments. The results indicate that different driver characteristicsand travel characteristics would result in significantly different decisions on route adjustment in traffic congestions. Forexample, men, the elderly, and drivers with less driving experiences, less frequent travels, and flexible travels are morelikely to keep the original route than other groups; when the driving distance increase cause by the route adjustmentaccounts for a large proportion of the remaining driving distance, of the driver is more likely to keep the original route.Drivers who are familiar with the road network are 11.3% times more likely to maintain the original route than otherdrivers; for every increase of 1 km · h- 1 running speed, the probability that the driver maintains the original route is1.223 times than before speed increases.
