白行车阻滞干扰对交通流的延误影响模型

摘要

Traffic flow mixed motor vehicle and bicycle is the main characteristic of the urban traffic in China. Bicycles will cause interference influence on motor vehicles and traffic flow delays in the mixed traffic, which has not been studied comp]etely because of lacking the mathematical model and calculation method. Aiming at the discrete flow and continuous flow respectively, an impact model of traffic flow delays caused by bicycle blockinterference was established according to the probability theory and hydrokinetics simulation theory. To some extent, this model could be used to evaluate the road service level and determine reasonable road resistance function.%机非混合交通流是我国城市交通的一个主要特征，在机非混行路段，自行车对机动车的行驶会造成干扰影响，容易造成交通延误，目前尚缺乏对这种延误进行分析的数学模型和计算方法．本文针对交通流中出现的离散流和连续流的不同情况，分别采用概率论理论和流体动力学理论两种不同的方法提出了机非混行路段的自行车阻滞干扰对交通流的延误影响模型。该模型对于定量分析混合交通中自行车对路段交通流的影响，对于评价路段的服务水平，确定合适的路阻函数等具有重要的意义．
