Geometric Layout Dependent Passenger Car Equivalent of Motorcycle

抄録

Mixed traffic with high motorcycle traffic composition is the specific feature of the road traffic in Taiwan and in most Southeast Asian countries. For planning and managing the road traffic, it is usually to convert motorcycles into Passenger Car Unit (PCU) by the Passenger Car Equivalent (PCE) of the motorcycle The PCE of the motorcycle will be different because of different traffic composition and different geometric layouts. This paper used a regression model to investigate the relationship of the PCE of the motorcycle with the lane allocation, and the location characteristics of intersections under various traffic flow situations. According to the modeling results, the passenger car equivalent of the motorcycle can be given with different mixture rates for different lane layouts. The result can be applied for designing the signal time and enhancing intersection performance using the more suitable PCE of the motorcycle.
