The paper has first built the vehicle-borne computer sensing integration testing system experiment platform, through the actual road test experiment, collects the different mobile vehicle the operating condition data and emission data, has constructed the different vehicle instant exhaust emission rate and database of vehicles driving cycle-based data correspondence, Establishes the driving cycle and road grade power density microscopic emission model. Uses the typical path roundabout crossing as an example, the paper carries on the power density computation through microscopic simulation software numerical simulation output roundabout crossing region vehicle bicycle the real-time speed, acceleration and other travel data, combined with the previous microscopic emission model of building, calculates the instantaneous mass emission rate and vehicles total emission of roundabout crossing different vehicles pollutant gas. According to the result of software simulation and numerical computation, the paper effectively appraises the regional road roundabout pollution emitted by vehicles, has verify the validity of the in-vehicle computer sensor integration testing and emission assessment model, provide a reference for seeking to solve regional traffic roundabout environmental pollution testing methods and effective assessment.
