摘要/Abstract

摘要： 为探究道路交叉口货车右转弯过程中货车司机的视线盲区形成机制,以及货车右转对交叉口安全的影响,运用Matlab软件建立货车右转弯模型。基于对载重货车内轮差的特性分析,以及模型车试验和现场大型货车转弯试验结果,修正转弯轨迹,较精准地模拟货车转弯过程。提出盲区面积计算方法和道路交叉口安全性评估指标。对右转分离式路口、缓转弯十字路口和急转弯十字路口进行基于货车右转盲区的安全性评估。结果表明:6轴载重货车的右转弯盲区面积达40.39 m²,与常见的普通十字路口相比,右转分离式路口有较高行车安全性。

Abstract: In order to explore the formation mechanism of truck drivers' blind area when the truck is turning right, and the influence of truck turning right on safety of the road intersection, a right-turn model was built by using the Matlab software. Based on analyzing the characteristics of truck's inner wheel difference, the results of test of model car and results of large trucks turning tests, and fixing trajectory turning, the turning process of truck was simulated accurately. A method was worked out for calculating the visual blind area. A index was putforward for road intersection safety evaluation. A truck right-turn blind spot area based evaluation of safety was made for right-turn separation, slow turn interaction and sharp turn interaction. The results show that the blind area is 40.39 m² for six-axle truck turning right, and that right-turn separation crossing has higher safety.

Key words: heavy truck, visual blind spot, simulation track, mechanization, intersection evaluation
