Abstract

Problem. The problem of distributing competing flows of road users in time is prevalent worldwide, and there is no fully justified and intelligible solution, even if only traffic flows can be considered. At the busiest street intersections, the primary means of traffic management is traffic signal control. If the traffic lights are close to each other, then it is a good practice to coordinate the operation of such traffic lights to organise the most unhampered movement of vehicles in one or several directions; that is the progression. Goal. The goal is estimation of the time required to ensure the uniform motion of vehicle platoon progression on the coordinated artery of the city arterial. Methodology. The developed approach is based on the use of analytical research methods and allows to formalize the interaction of the platoon progression with additional vehicles. Results. The results of the estimation of the minimum time required to ensure the uniform motion of the platoon progression allow us to state that for actual speeds and vehicle accelerations when starting from the stop-line of the intersection, the requirement for the uniform motion of the platoon progression is too strict, especially if we take into account that advance time will increase significantly as the number of additional vehicles in the queue increases. Originality. Analytical models created using formulas of the kinematics of rectilinear uniform accelerated motion of a point make it possible to estimate the minimum advance time of the start of the traffic light signal due to the deliberate speed of traffic and the average acceleration of one additional vehicle when starting from the stop-line of the intersection. Practical value. The developed models reflect the minimum value of the advance time, which ensures uniform motion of the platoon progression, provided that there is one additional vehicle at the stop-line of the intersection.
城市主干道协调路段上保证车辆队列运动均匀所需时间的估计方法
问题。及时分配道路使用者竞争流量的问题在世界范围内普遍存在,即使只考虑交通流量,也没有完全合理和可理解的解决办法。在最繁忙的十字路口,交通管理的主要手段是交通信号控制。如果交通灯相距很近,那么最好是协调这些交通灯的操作,以组织车辆在一个或几个方向上最不受阻碍的运动;这就是进展。的目标。目标是估计车辆排在城市主干道的协调动脉上均匀运动所需的时间。方法。所开发的方法是基于分析研究方法的使用,并允许将排的进程与其他车辆的相互作用形式化。结果。通过对保证队列匀速行进所需最小时间的估计,我们可以得出结论:对于从交叉口停车线出发时的实际速度和车辆加速度,对队列匀速行进的要求过于严格,特别是考虑到随着队列中车辆数量的增加,提前时间将显著增加。创意。利用点的直线均匀加速运动运动学公式建立的分析模型,可以估计出从交叉口停车线出发时,由于交通的故意速度和一辆额外车辆的平均加速度,交通灯信号开始的最小提前时间。实用价值。所建立的模型反映了当在交叉口停车线处有一辆额外车辆时,保证队列运动均匀的提前时间最小值。
