Heavy vacation traffic this Labor Day weekend was the final test for New Hampshire’s new statewide E-ZPass toll system, and it passed with flying colors. TRMI designed and developed a 102-lane E-ZPass electronic toll collection system installed at 10 toll plazas for the New Hampshire Department of Transportation (DOT). The turnkey project included automatic coin machines installed in 32 lanes for coin and token payments, and front and rear camera video enforcement systems were installed in 50 dedicated electronic toll collection (ETC) lanes.
“We had the system up and running far faster than we thought we would,” said Charlie Mitchell, Vice President of TRMI. “We took a conversion schedule designed for four months in winter with light traffic and made it happen in six weeks with heavy summer traffic.”
The system TRMI developed for New Hampshire also delivers high performance at a low cost. It features wide-area network communications using low-cost broadband connections, which are designed to save the Department of Transportation approximately $90,000 per year in operating costs. Redundant servers at DOT headquarters host an Oracle database and Microsoft web server.
TRMI’s lane design uses Mark IV Industries’ IAG RoadCheck Redundant Readers and OSI AutosenseII overhead laser scanners. TRMI’s internally developed lane software includes a high-speed look-up engine which is capable of finding the account status for any transponder in a tag file of over 180 million tags in under one tenth of a second.
“We are currently providing 24-hour on-site maintenance support,” said Mitchell. “And future high-speed lanes will utilize the same technology we’ve developed.”
