Evaluation Report for ITS for Voluntary Emission Reduction: An ITS Operational211 Test for Real-Time Vehicle Emissions Detection

摘要

The Intelligent Transport Systems (ITS) Operation Test Project was designed to211u001eassess the potential of ITS to support cleaner air by providing real-time vehicle 211u001etailpipe emissions information (carbon monoxide levels) to the driving public. It 211u001emade an appeal to the driving public to accept responsibility for maintaining 211u001etheir vehicles, to increase gas mileage and minimize harmful tailpipe emissions. 211u001eThe ITS Operational Test Project combined a variable message sign/SMART SIGN 211u001e(VMS) with a remote sensing device (RSD). The merging of these technologies into 211u001ea remote sensing information system (RSIS) made possible, for the first time, 211u001eprovision to the public of real-time tailpipe emissions information from the 211u001evehicle they are driving. The purpose of this project was to test the accuracy of 211u001ethe combined system and to evaluate the motorists perceptions and responses to 211u001esuch a system. This was a unique project because it combined new technologies, 211u001eprovided the potential for dramatically increasing awareness, made an appeal to 211u001ethe minority of gross polluting vehicle motorists to accept responsibility for 211u001etheir dirty cars, and alerted owners of normally low emitting vehicles if an 211u001eemission system failure had occurred.
