Method of estimating the change in life cycle CO 2 due to transport system development incorporating micro-traffic flow simulation

摘要

In this research, a method of estimating the system overall life cycle CO2emissions including vehicle traveling, infrastructure construction, and new manufacture of vehicles is constructed in order to comprehensively evaluate the change in CO2emissions associated with transport system development. In particular, congestion of automobiles due to traffic signals and turning left and right, etc., and the detailed driving behavior of vehicles including mixing of light rail transit (LRT) and automobiles on the road can be analyzed by micro-traffic flow simulation. A framework is presented for the introduction of LRT that enables conversion from parallel fixed route buses and the increase in congestion of automobiles due to the reduction in the number of traffic lanes to be taken into consideration. As a result of application of this estimation method to a case study, the effect of automobile congestion brought about by the reduction in the number of traffic lanes and the introduction of LRT priority signals on CO2emissions was quantitatively determined.
