Abstract

The safety of vulnerable road users, especially pedestrians, on Polish roads remains among one of the lowest levels among EU countries. A high number of accidents involving pedestrians occur in areas with zebra crossings, and excessive speed is often mentioned in police records as a leading cause of accidents. A number of investigations highlight that drivers’ speed strongly influences the impact on pedestrian safety; hence, it should be controlled in areas with pedestrian crossings through effective management. According to traffic law regulations, drivers are required to give special attention and slow down while approaching a pedestrian crossing. The aim of the article is to explore drivers’ speed behaviors at zebra crossings depending on their localization. Investigated zebra crossings were located on single and dual carriageways on straight segments and approach sections of intersections without traffic lights. Speed measures were performed under freeflow traffic conditions. The conducted analysis allowed for the identification of road geometry-related parameters significantly influencing vehicles’ speeds at pedestrian crosswalk locations. Based on the analyzed parameters, regression models were developed and validated.

人行横道区域的速度分析与建模

波兰道路上弱势道路使用者，特别是行人的安全水平仍然是欧盟国家中最低的。有斑马线的地区发生了大量涉及行人的事故，在警方的记录中，超速经常被提到是导致事故的主要原因。多项调查表明，驾驶员的速度对行人安全的影响很大;因此，应该通过有效的管理，将其控制在有人行横道的地区。根据交通法规，司机在接近人行横道时必须特别注意并减速。本文的目的是探讨司机在斑马线上的速度行为，这取决于他们的定位。被调查的斑马线位于单行道和双行道的直行路段和没有红绿灯的交叉路口的接近路段。在自由交通条件下进行速度测量。所进行的分析允许识别道路几何相关参数显著影响车辆在人行横道位置的速度。根据分析的参数，建立了回归模型并进行了验证。
