Abstract

This study analyzed the impact of driving environments (real-world and simulated world) and driving conditions (no time pressure and time pressure) on speed compliance and speed adaptation. Professional car drivers were recruited, and the data was collected in real-world and simulated world under no time pressure and time pressure driving conditions. The comparison results using Wilcoxon-signed rank test showed that speed compliance and speed adaptation were not consistently significant and were not in the same direction highlighting the influence of various factors like road features and driver characteristics. The generalized linear mixed model results showed that speed compliance was relatively better in simulated world (by 3.98 kmph) than real-world. Further, speed adaptation under time pressure was about 5.86 kmph lower during real-world as compared to simulated world. The findings from this study can provide new insights on road safety strategies and policy implications for limiting speeding-related crash risks.

职业驾驶员在不同驾驶环境和驾驶条件下遵守速度规定和速度适应的影响评估

本研究分析了驾驶环境（真实世界和模拟世界）和驾驶条件（无时间压力和有时间压力）对速度依从性和速度适应性的影响。研究招募了职业汽车驾驶员，在真实世界和模拟世界中的无时间压力和有时间压力驾驶条件下收集数据。使用 Wilcoxon-signed 秩检验的比较结果表明，速度顺应性和速度适应性的显著性并不一致，而且方向也不相同，这凸显了道路特征和驾驶员特征等各种因素的影响。广义线性混合模型的结果表明，模拟世界的车速顺应性（每小时 3.98 公里）比真实世界的车速顺应性要好。此外，在时间压力下，真实世界的车速适应性比模拟世界低约 5.86 公里/小时。这项研究的结果可以为限制超速相关碰撞风险的道路安全策略和政策影响提供新的见解。

期刊介绍： Transportation Letters: The International Journal of Transportation Research is a quarterly journal that publishes high-quality peer-reviewed and mini-review papers as well as technical notes and book reviews on the state-of-the-art in transportation research. The focus of Transportation Letters is on analytical and empirical findings, methodological papers, and theoretical and conceptual insights across all areas of research. Review resource papers that merge descriptions of the state-of-the-art with innovative and new methodological, theoretical, and conceptual insights spanning all areas of transportation research are invited and of particular interest.
