| 摘 要： | 为了减少城市主干道出现局部拥堵,提出一种基于logit模型的城市主干道交通流分配方法。根据路段通行能力、路径延误时间和路径流量综合考虑,通过计算每条路段选择的概率大小,将交通流分配到路段上。同时改进了STOCH算法,通过实例对比验证,改进后的模型,不会出现单条路段拥堵,表明模型具有更好的分配能力。

| Abstract: | In order to decrease the chance of urban road partial congestion,this paper tries to present a distribution method of urban main road traffic flow based on model logit. Taking a thorough consideration of traffic capacity on link,path delay time as well as path traffic flow,this paper aims to calculate the specific possibility of each road section being chosen. Thus the traffic flow will be assigned to road sections. In addition,algorithm STOCH is improved in some way. The improved model will avoid being congested in one single road by comparison validation with specific examples,thus showing a better distribution capacity of the model. |
