The Intelligent Transport System’s (ITS) Operation Test Project was designed to assess the potential of ITS to support cleaner air by providing real-time vehicle tailpipe emissions information (carbon monoxide levels) to the driving public. It made an appeal to the driving public to accept responsibility for maintaining their vehicles, to increase gas mileage and minimize harmful tailpipe emissions. The ITS Operational Test Project combined a variable message sign/SMART SIGN (VMS) with a remote sensing device (RSD). The merging of these technologies into a remote sensing information system (RSIS) made possible, for the first time, provision to the public of real-time tailpipe emissions information from the vehicle they are driving. The purpose of this project was to test the accuracy of the combined system and to evaluate the motorists’ perceptions and responses to such a system.
