STUDY OF CO2 EMISSION ESTIMATION AND CLARIFICATION OF CONGESTION LENGTH USING DSRC PROBE DATA

摘要

The National Institute for Land and Infrastructure Management of the Ministry of Land,Infrastructure, Transport and Tourism has responded to the Joint Public and Private SectorResearch on Next Generation Road Service Provision Systems implemented under ITS Entersthe Second Stage (August 2004) proposed by the Smartway Promotion Committee, bydeveloping technologies for next generation road services which will use the DSRCroad-vehicle communication system [1] [2]. Past studies include a probe data collection testusing roadside equipment installed on an urban expressway and center equipment, whichconfirmed that it is possible to obtain probe data with a DSRC road-vehicle communicationsystem[3]. It also showed the directions of DSRC probe data use taking the comparison ofbehavior history data and accident hot spot information as an example [3][4]. This paperreports on the results of a study, conducted based on the results of past studies, to estimateCO_2 emissions using DSRC probe data, with reference to a variety of newly obtained vehicledata.
