Analisis Perilaku Pengemudi Sepeda Motor di Persimpangan Bersinyal Kota Medan

Abstract

Traffic violation behavior of motorcyclist such as running red lights, driving and waiting in the wrong lane is one of the dominant factors in motorcycle traffic accidents at signalized intersections in Medan City. Prevention of this behavior can be done by understanding how motorcyclist behave from various signalized intersection characteristics. Therefore, this study observes naturally the behavior of motorcylict at five signalized intersections prone to traffic accidents in Medan using CCTV. The Multiple Correspondence Analysis (MCA) method is used to explore various characteristics of the driving environment at signalized intersections that can stimulate motorcyclist behavior. The violation behavior of motorbike drivers in Medan City is included in the ordinary category. High-risk traffic violations, namely risk-taking running red lights (23%) and going against the flow (10%), while traffic violations that are not high-risk are dominant, such as opportunistic running red lights (50%), waiting at the zebra crossing (34%), waiting outside the road (27%), and traffic following running red lights (26%), and driving on sidewalks (17%). MCA results show that various characteristics of signalized intersections such as distance across, lane width, red light duration, vehicle volume, median, road island, and others stimulate various adaptations of motorcycle driver behavior. The behavior of motorcyclist violating traffic is stimulated by the characteristics of wide lane width, long red lights, no median, and others. This arises because of feeling uncomfortable with the environment and there is an opportunity. While the behavior of motorbike drivers does not violate traffic, it is stimulated by signalized intersection characteristics such as long crossing distance, high crossing volume, and others. This arises due to the high perception of the risk of collision by motorcyclist. This study suggests implementing an actuated traffic light system, elevating the median, and completing transverse rumble strips.
