MNPASS EASY: KEEPING THE H.O.T. LANE HOT

摘要

The MnPass High Occupancy Toll (HOT) lane facility on I-35W operates without physical barriers between the HOT lane and the adjacent general-purpose lanes. This arrangement offers configuration flexibility and low construction costs, but is dependent upon adequate enforcement to ensure that only high-occupancy and transponder-equipped vehicles use the facilities. Enforcement of the I-35W HOT lane facility is limited by scarcity of safe shoulder areas along the corridor to observe and stop suspected violators. As a result, Minnesota State Patrol troopers often have to follow potential HOT lane violators substantial distances before a safe shoulder area is reached. This limitation contributes to high violation rates. The EASy concept uses technology as an aid to safely and efficiently identify possible illegal users of the I-35W MnPass facility. This concept includes both existing and new components at two enforcement station locations. Goals include enhancing both trooper and public safety and decreasing the number of false-positive enforcement stops. The increased enforcement efficiency may potentially lead to greater compliance from the traveling public.
