滞车时间分析

Analysis of Traffic Residence Time

分析了双车道路面因养护施工而单向放行时的滞车时间与单向放行路段长度、车速、车距、交通量等影响因素的关系,在此基础上得出了滞车时间的具体计算公式,并提出了缩短滞车时间的途径。滞车时间计算公式表明:滞车时间与单向放行路段长度成正比;当单向小时车流量接近一临界数值时滞车时间将迅速增加。缩短滞车时间的途径有三:控制施工路段长度;提高放行车速及严格现场交通管制。

The relationship of traffic residence time with road length, vehicle speed, vehicle distance and vehicle flow in the unidirectional running when the double lane pavement is in road maintenance is analyzed. On this basis, specific formulas of traffic residence time are deduced, the approach of shortening residence time of traffic is proposed. The calculation formula showed that residence time of traffic is proportional to length of unidirectional running road section, and will increase rapidly when the vehicle flow approaches a critical value. There are three methods used for shortening residence time of traffic： controlling length of construction road section, inereasing vehicle speed and carry out traffic control in the field.
