For improving the traffic problems effectively, we need to understand the characteristic of mixed traffic flow. In the previous studies, the capacity of an approach of a signalized intersection is estimated by the saturation flow rates. However, the discharging behavior of the mixed traffic is also affected by the stopping pattern of automobiles and motorcycles, and the traffic patterns are not identical for every cycle due to the randomness of vehicle arrivals. These factors should be considered in determining the saturation flow rates and capacities of junctions. The objective of this study is to investigate the discharging behavior of vehicles in a mixed traffic at signalized intersections. Microscopic traffic data in the form of vehicle trajectory is collected, and the factors that could influence the discharge rate are analyzed. In the analysis, the queue platoon are divided into three sections: (1) motorcycle-only platoon, (2) motorcycle and car mixed platoon, and (3) car-only platoon. By adopting linear regression analysis, we propose a number of discharging time estimation models for different combinations of traffic mix. The result shows the discharging rate estimated by the proposed model has a good estimation performance. Wong, Ka-Io 黃家耀 2015 學位論文 ; thesis 70 zh-TW |
