高速公路收费标准 (或费率 )的高低将直接关系到其吸引交通量的多少 ,并进而影响到高速公路的营运效益。本文在分析了影响高速公路收费标准各因素的基础上 ,以交通量多路径概率分配模型为理论依据 ,就高速公路收费标准 (或费率 )的高低对交通出行的路径选择 (或分配 )及项目营运影响等进行研究分析。经综合研究分析 ,目前 ,我国绝大部分地区高速公路的合理收费标准 ,小客车一般在 0 .30～ 0 .5 0元 /小车·公里之间、中型标准车则在 0 .2 0～ 0 .4 0元 /当量小车·公里 (即 0 .4～ 0 .8元 /车·公里 )之间 ,并随着经济的发展和交通需求的不断增加 ,其相应的合理收费标准将会不断提高 Expressway toll rates (or rates) will have a direct impact on the amount of traffic it attracts, and thus affect the expressway’s operating efficiency. Based on the analysis of various factors influencing expressway toll rates, taking the probability distribution model of traffic multipath as the theoretical basis, this paper analyzes the selection (or distribution) of toll road toll (or rate) Project operation impact analysis and research. After a comprehensive study and analysis, at present, most of the reasonable toll rates for expressways in our country are generally between 0.30 ~ 0.50 yuan / trolley km and medium-sized standard cars between 0. 0 ~ 0 .4 0 yuan / equivalent trolley km (ie 0 .4 ~ 0 .8 yuan / car km), and with the economic development and increasing traffic demand, the corresponding reasonable fees will continue to increase
