The Electronic Toll and Traffic Management (ETTM) project at Rensselaer Polytechnic Institute (RPI) was sponsored by the New York State Department of Transportation (NYSDOT) and the Federal Highway Administration (FHWA).

Rensselaer, in conjunction with Mark IV Industries developed a prototype wireless, solar powered E-ZPass tag reader. The device has been demonstrated as a viable means of observing traffic as part of an Automated Vehicle Identification (AVI) system.

The purpose of this project was to demonstrate that a wireless, solar powered tag reader is a viable solution for field deployment, and to report on a demonstration of RFID tag reader technology in collecting link travel times where permanent installations are not practical.

Portable units similar to these could be used for traffic management on local arterials, incidents or during special events or work zones and shall cut the present dependence on power and wired telecommunication access so that the device shall be deployable anywhere, anytime.

The wireless solar powered E-ZPass tag readers were deployed and tested at two locations:

   - Route 4, North Greenbush, New York (July - August 2007 and October      2007 - January 2008)

   - New York State Fair, Syracuse, New York (late August 2007 and 2008)
