The objective of this study is to explore the potential for electric motorcycles to support a developing Asian city to be a low carbon society. The study surveyed the attitudes of motorcyclists to determine the proportion of motorcyclists willing to use an electric motorcycle and also estimated the reduction of CO2 emission from the transport sector in Khon Kaen city, Thailand. The approach Bottom-Up2 by road network with the transport demand forecasting model and emission factors by vehicle type were used to calculate CO2 emissions for each road link. 16% of motorcyclists currently using gasoline motorcycles would be willing to use electric motorcycles in the near future. To evaluate CO2 emission reduction, the future condition with introduced electric motorcycles was compared to the future do-nothing condition in the same future year. The evaluation result reveals that the electric motorcycle introduction could reduce 2.4% of CO2 emitted by the transport sector from the future do-nothing condition.
The objective of this research was to evaluate the efficiency of the motorcycle-specific pausing zone under the Bike Box Project (BBP). This zone is designated at the very front of the waiting line for the traffic light. The indicators used to measure the efficiency comprised the lost time when starting up at the beginning of the green light, the change of the proportion of the motorcycle pausing points, the accident statistics, and the worthiness for investment. Two intersections in urban areas were used for the analyses and evaluation, which were carried out to compare between the period prior to and after the project began. The study indicated that after the project began, the start-up lost time could be reduced by roughly 31-46% during peak hours, with approximately 73-78% of motorcycles pausing in the green zone (Bike Box Zone). The number and severity of the traffic accidents after 1-year of BBP implementation significantly decreased. The results of the study showed the efficiency of traffic management, safety, and worthiness for investment. It is thus appropriate to extend the project to other areas in the country and abroad, especially in urban areas where motorcycles are greatly used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
