摘要
目前交通量分析与预测多采用BPR函数等单一修正行程时间的延误函数,对通行费用考虑较少。引入广义费用延误函数,综合考虑高速公路的行程时间、通行费用等因素,然后,介绍广义费用延误函数在高速公路交通分配中使用方法,最后结合具体实例与BPR延误函数的交通分配结果对比,验证了此方法更适用于高速公路等受多因素影响路径选择的交通分配。
BPR delay function and other delay functions about single consideration of travel time are used in the traffic volume analysis and prediction at present,and less consideration is given to the traffic cost.In this paper,the generalized cost delay function is introduced in order to consider the complex factors such as travel time and traffic cost.Then,the method of using generalized cost delay function in traffic assignment of freeway is introduced.Finally,combined with specific examples,this method is more suitable than BPR delay function for the traffic assignment affected by many factors such as freeway.
