It is necessary to clarify the roadside air pollution mechanism caused by exhaust emissions from running vehicles. In order to analyze its mechanism, simple simultaneous on-board measurement system for road infrastructure, traffic conditions, vehicle running behavior, driver's operation and actual exhaust emissions based on distance was developed. The measurement system was installed in a light duty freight vehicle. For demonstrating accuracy of the exhaust emission measurement system, tests on chassis-dynamometer that include steady state and transient cycles, and tests on actual road were conducted. The results of tests on chassis-dynamometer showed enough accuracy to evaluate NOx emissions from a vehicle at local roadsides by optimizing the attachment position of sensors in the exhaust line. In the actual running tests, it was demonstrated that the developed system was effective to evaluate NO x emission from a running vehicle at local roadside, and also to analyze local roadside air pollution caused by running vehicles.
