TransCore Introduces the "Green Calculator" : RFID Technology Helps Parking Authorities Reduce Carbon Emissions at their Facilities

Share Article

To evaluate the current state of a parking facility’s associated environmental impact, TransCore introduces the “Green Calculator,” an online tool to estimate carbon dioxide output at parking facilities. The convenient tool estimates carbon footprint of a facility by assessing traffic volume and average vehicle idle time. The calculator can be accessed at

Streamlining a facility's traffic flow and lowering the duration of idling can be significant, particularly when you multiply that times the number of parking facilities across the country

Wireless radio frequency identification (RFID) technology used for parking and access control, and also deployed for wireless payment of tolls throughout the country, allows vehicles to enter and exit parking garages virtually without stopping, keeping access smooth and back ups limited. This results in reduced idle times and significantly decreases carbon emission output on a consistent basis. An estimated 25-30 percent decrease in idle times is possible utilizing RFID-based automatic vehicle identification technology.

The Green Calculator helps parking facility owners and managers to quickly assess their facility's emissions environment and make strategic decisions regarding access control solutions that can provide added benefits to improving air quality levels.

"Streamlining a facility's traffic flow and lowering the duration of idling can be significant, particularly when you multiply that times the number of parking facilities across the country," said Clint Duncan, TransCore's general manager RFID Asset Tracking.

As technology continues to erase boundaries and convenience becomes central to customer service, acceptance of wireless payments systems for applications such as paying for parking or access to gated communities has grown. TransCore's technology, with more than 35 million tags and 55,000 readers deployed in various transportation applications in 41 countries, has been effectively deployed in parking facilities including corporate and university campuses, hospitals, commercial parking garages, residential communities, and resorts throughout the country.

The sleeker, batteryless RFID-based eGo® window sticker tag provides environmental benefits as well. The smaller profile tag consumes less petroleum based raw material to manufacture and reduces transportation and shipping requirements. The batteryless design of the tag eliminates the additional cost and demand for batteries' and subsequent storage and disposal requirements.
