Evaluation Study on Start-up Lost Time Reduction of Exclusive Stopping Space for Motorcycle at Signalized Intersections

Abstract

The objective of this study is to evaluate the exclusive stopping space for motorcycle at signalized intersection on reducing a start-up lost time due to a change of motorcycle’s stopping position. Three signalized intersections were selected as the study intersections, including the in front of Ubon Ratchathani University intersection in Ubon Ratchathani Province, the Phayu Intersection in Sisaket Province, and the Ban Phai Intersection in Khon Kaen Province. The study results found after a construction of an exclusive stopping space for a motorcycle at signalized intersections, lanes with a high number of stopping motorcycles and high rate of motorcycle stopping in exclusive stopping space during red time significantly achieved a reduction of start-up lost time of traffic. The study on relationship

between the stopping position and start-up lost time found that intersection with exclusive stopping space for motorcycle and a red time cycle with higher number of motorcycles stopping in exclusive stopping space for motorcycle or in area behind the stop line and in front of a vehicle queue resulted in lower start-up lost time of traffic. In contrast, intersection without exclusive stopping space for motorcycle and a red time cycle with higher number of motorcycles stopping in the vehicle queue resulted in higher start-up lost time of traffic.
