Abstract

Side friction refers to combined variables indicating the degree of interaction between the activities and the traffic stream. The condition worsens when the transport demand and road-side activities increase, leading to inefficient traffic performance. This study has been focused on evaluating side friction impacts in terms of capacity and speed. Four links divided and undivided streets in Al-Najaf City, Iraq, were selected and on-street parking, pedestrian activities, entry-exit maneuvers, and temporary parking vehicles are considered as side friction elements. The results show about a 47% reduction in speed and about a 49% reduction in the capacity at a very high side friction level. Finally, a speed-predicting model has been developed for predicting the speed under side friction impacts.

分隔和未分隔街道侧摩擦对城市街道性能的影响

侧面摩擦是指表明活动和交通流之间相互作用程度的组合变量。当运输需求和路边活动增加时，情况会恶化，导致交通效率低下。本研究的重点是从容量和速度方面评估侧面摩擦影响。选择了伊拉克纳杰夫市的四条连接分隔和不可分割的街道，并将路边停车、行人活动、出入境机动和临时停车车辆视为侧摩擦因素。结果表明，在非常高的侧摩擦水平下，速度降低了约47%，容量降低了约49%。最后，建立了一个速度预测模型，用于预测侧面摩擦碰撞下的速度。
