Abstract

This study examined the influential roadway and contextual factors affecting drivers' speed selection through a comprehensive investigation employing structural equation modeling. Roadway and contextual variables including road curvature, presence of roundabouts, adverse weather conditions, and access were investigated using infrared speed sensors. The analysis revealed that specific roadway and contextual factors such as field variables, uphill and downhill road inclines, particular road curvature, and rainy weather significantly influence drivers' chosen speeds, while factors such as road access, nighttime conditions, larger road curvature, and signage exhibit a lesser impact. Notably, the study also found a positive correlation between road curvature radius and driver-chosen speed. The study's implications for transportation infrastructure planning and road safety interventions are underscored, with potential applications in road design, signage improvement, and weather-responsive measures to regulate driver speed choices in specific roadway and contextual conditions.

了解环境因素对驾驶员车速的影响：结构方程模型分析

本研究通过采用结构方程模型进行综合调查，研究了影响驾驶员车速选择的道路和环境因素。研究使用红外测速传感器对道路和环境变量进行了调查，包括道路曲率、是否有环岛、恶劣天气条件和交通状况。分析结果表明，特定的道路和环境因素，如现场变量、上坡和下坡道路坡度、特定的道路曲率和阴雨天气，对驾驶员选择的车速有很大影响，而道路通行、夜间条件、较大的道路曲率和标志牌等因素的影响较小。值得注意的是，研究还发现道路曲率半径与驾驶员选择的车速之间存在正相关。该研究对交通基础设施规划和道路安全干预措施的影响得到了强调，并有可能应用于道路设计、标志牌改进和天气响应措施，以调节驾驶员在特定道路和环境条件下的车速选择。

期刊介绍： First published in 1977 as an international journal sponsored by the International Association of Traffic and Safety Sciences, IATSS Research has contributed to the dissemination of interdisciplinary wisdom on ideal mobility, particularly in Asia. IATSS Research is an international refereed journal providing a platform for the exchange of scientific findings on transportation and safety across a wide range of academic fields, with particular emphasis on the links between scientific findings and practice in society and cultural contexts. IATSS Research welcomes submission of original research articles and reviews that satisfy the following conditions: 1.Relevant to transportation and safety, and the multiple impacts of transportation systems on security, human health, and the environment. 2.Contains important policy and practical implications based on scientific evidence in the applicable academic field. In addition to welcoming general submissions, IATSS Research occasionally plans and publishes special feature sections and special issues composed of invited articles addressing specific topics.
