Abstract
At the statistics of urban arterial accident in 2004, it accounted for all more than two-third accidents that were correlated with the behavior of lane-changing, so it is known that how the valuable study should be done at the topic of lane-changing collision avoidance on urban arterial. But the study about lane-changing merely stressed on the lane-changing behavior discussion on freeway. Therefore, the objective of this study will focus on the setting lane-changing collision avoidance system on urban major arterial, and by the survey of lane-changing behavior, drawing up a set of lane-changing collision avoidance threshold to alarm drivers when they want to execute the strategy of lane-changing. By this way, it can decrease the probability of lane-changing collision and the severity of lane-changing accident. The study used photography above high building to collect the sample of lane-changing, and then analyzed the relationship between gap and relative speed within various vehicles to establish the lane-changing collision avoidance system toward ordinary lane and target lane. In this study, the correlative traffic parameters revealed the driver’s lane-changing behavior on urban major arterial and the influential difference by the surrounding vehicles. The influential scope of surrounding vehicle had been decided in this study: lead vehicle and adjacent lead vehicle are 30 meters in front of subject vehicle, and adjacent following vehicle is 15 meters in back of subject vehicle. Eventually, the study uses three kinds of light alarm ways (green light, yellow light, and red light) to give a warning of lane-changing to drivers and suggests them to make a relevant improvement strategy to avoid a collision occurrence.
