信号控制交叉口助动车违章特征与影响因素分析

Violation Characteristics of Moped Riders and Influential Factors at Signalized Intersections

为了对助动车的违章行为提出改进措施,利用视频数据观测了上海市12个信号控制交叉口的骑行类车辆行为。基于行为分析方法对人-车-交通环境特征进行编码,并利用Logit模型分析了助动车违章行为的影响因素。结果显示,在信号周期较短、非机动车流量较小、横向车流较稀疏或处于违章待行状态时,助动车更易闯红灯;在直行或非机动车道较窄时,更易违章待行;在转弯、非机动车道较窄或横向车流稀疏的情况下,更易错用车道;在非机动车道较宽时,更易逆行;燃油/燃气车辆、男性骑车者更倾向于载人载物违章。最后指出,应建立助动车骑车者的安全意识、完善法律法规、提升交通设施服务质量与交通管理水平,以有效引导助动车向有利于城市交通有序、安全方向发展。

In order to propose effective countermeasures for moped violations,this paper investigates the moped riders’ behaviors through videotaping at 12 signalized intersections in Shanghai.The paper encodes the characteristics of riders,mopeds and traffic environment based on the behavioral analysis method and analyzes the factors affecting moped violation behaviors using the Logit model.The results show that 1） shorter cycle lengths,smaller non-motorized traffic volume and less conflicting traffic may increase the probability of moped red light running;2） moped riders tend to wait improperly when the through lanes or the non-motorized lanes are narrow;3） when the turning lanes or the non-motorized lanes are narrow or the conflicting traffic is light,the probability of mopeds using wrong lanes may increase;4） broader non-motorized lanes may increase the probability of moped retrograde motion;and 5） fuel or gas vehicles and male riders increase the probability of moped overloading.Finally,the paper points out that safety consciousness for moped riders,traffic laws and rules,and traffic facilities should be improved to guide an ordered and safe urban transportation system.
