Abstract
Mixed traffic flow is always a complicate topic in the field of transportation science. In Taiwan, the ratio of motorcycles to non-motorcycles is approximately 1:1, and in average number of every 1.5 people have a motorcycle. Therefore, the impact of motorcycle in traffic is significant enough to be considered. Unlike the Southeast Asian countries, the advanced countries rarely discuss the behavior of motorcycles on the study of traffic in the past. However, they mostly only study on road section, not intersection. In 1999, the government began to set up different motorcycle facilities at intersections because of the large number of motorcycles in Taiwan. These facilities change the geometric of intersections. In order to understand the behavior of motorcycles at signalized intersections, this study models a microscopic discharge motorcycle model through real traffic flow data collection. The model bases on safety distance, which is called safety threshold in this study, between influence vehicles. After comparing with different shape, parabola is the best to describe safety threshold. This study establishes, moreover, interaction relationship between motorcycle-passenger car and motorcycle-motorcycle base on acceleration varying. At the same speed, Motorcycle is easier to accelerate in shorter distance than other vehicles. Finally, through visual computer simulator to simulate motorcycle discharge at signalized an intersection. The discharge rate, discharge speed and discharge trajectory is tested with several cycle data and obtain good performance.
