Analysis of Traffic Safety Issues Inside Right-Turn Protection Zones at Intersections Based on Road Right-of-Way Optimization

为解决交叉口右转保护区内非机动车与行人通行的安全和效率问题，文章以国内城市广为实施的交叉口右转保护区为研究对象，基于路权明晰化与空间分离理念，优化现有右转保护区的内部区域，实现人非分流。实证表明，优化方案可有效降低交叉口右转保护区内交通冲突率，提升交叉口通行效率。To address the safety and efficiency issues of non-motorized vehicle and pedestrian movement in right-turn protection zones at intersections, this paper takes the right-turn protection zones widely implemented in domestic cities as the research object. Based on the concepts of clear road right-of-way and spatial separation, the internal areas of existing right-turn protection zones are optimized to achieve the separation of pedestrians and non-motorized vehicles. Empirical evidence shows that the optimization scheme can effectively reduce the traffic conflict rate in right-turn protection zones at intersections and improve the traffic efficiency of intersections.
