Over the past few decades, a growing attention has been directed toward cycling due to its positive impacts on social, economic, and health aspects. Various countries are adopting and implementing strategies to promote cycling as a daily mode of transport. The main objective of this study is to improve cyclists’ safety by investigating the impact of different layouts of on-road cycle lanes at two-lane two-way roads on drivers’ interactions with cyclists using driving simulator. Three layouts of on-road cycle lanes were tested and compared, namely, uncolored, colored, and island separation, along with a control case where no cycle lane was provided. In addition, the impact of road alignments (straight sections, left and right curves) and the presence of an opposing vehicle were investigated. The driving simulator at Qatar University was used to conduct this study. A total of 92 subjects participated in this study. According to the results, on-road cycle lanes can significantly increase the safety of cyclists compared to shared lanes with motorized traffic. Moreover, the results showed that the drivers’ intrusion to the opposite lane in the presence of opposing vehicles can be eliminated by providing on-road cycle lanes. That is, drivers’ crash risk can also be reduced through the provision of on-road cycle lanes. Comparison of different on-road cycle lane treatments showed that uncolored cycle lanes outperformed the other layouts in terms of lateral clearance between the driver and the cyclist for right and straight alignments. On the other hand, the colored cycle lane showed better results for the left alignment. The findings of this study could be useful for designing on-road bicycle infrastructure to eliminate possible vehicle-cyclist and vehicle-vehicle conflicts and minimize crash risk.

在过去的几十年里，由于骑自行车对社会、经济和健康方面的积极影响，人们越来越关注骑自行车。各国正在采取和实施战略，以促进自行车作为日常交通方式。本研究的主要目的是通过使用驾驶模拟器调查双车道双向道路上公路自行车道的不同布局对驾驶员与骑车人互动的影响来提高骑车人的安全。对道路自行车道的三种布局进行了测试和比较，即无色、有色和岛分离，以及未提供自行车道的对照情况。此外，还调查了道路线形（直线路段、左弯和右弯）以及对面车辆的存在的影响。卡塔尔大学的驾驶模拟器用于进行这项研究。共有 92 名受试者参与了这项研究。结果显示，与机动交通共享车道相比，道路自行车道可以显着提高骑车者的安全性。此外，结果表明，通过提供道路自行车道，可以消除在对面车辆存在的情况下驾驶员闯入对面车道的情况。也就是说，通过提供公路自行车道也可以降低驾驶员的碰撞风险。对不同道路自行车道处理的比较表明，在驾驶员和骑车人之间的右侧和直线排列的横向间隙方面，未着色的自行车道优于其他布局。另一方面，彩色自行车道的左对齐效果更好。这项研究的结果可能有助于设计公路自行车基础设施，以消除可能的车辆与骑行者以及车辆与车辆的冲突，并最大限度地降低碰撞风险。
