An estimating method of CO_2 emissions from logistic vehicles using ITS Spot and GPS OBUs

摘要

In this paper, we propose a new method to estimate CO_2 emissions using probe data of logistic vehicles. In Japan, for estimating CO_2 emission of logistic vehicles, the "improved ton-kilometer method" is commonly used, in which the major parameter is the distance between the origin and the destination. Previous studies show the CO_2 emission estimation will be done correctly by using the behavior of vehicles, such as the change of speed or times of starts and stops. We have been developing the probe system consists of available RSUs and DSRC OBUs, which can collect the vehicles' location and speed in short (200m) trips. By adding up the emission of each short trip, the total emission will be estimated. Further, the field experiment using the system is explained briefly.
