摘要：	Electronic enforcement (EE) systems combine a camera with a "trigger" mechanism which, when the driver of a vehicle commits a certain traffic violation, causes a picture to be taken of the vehicle's license plate. Different automatic triggers can detect speeding, - both on freeways and residential streets - red light running and railroad crossing gate running. Although no automatic triggers currently exist to reliably count the number of people in a vehicle license plate imaging systems are being used to assist in the enforcement of HOV lane restrictions. Speed violation detection systems are usually mobile, in that they are set up in a police-owned van and moved from location to location with a minimal set-up time of about 30 minutes. Red light running and railroad gate running systems must be coupled with camera housings, poles, concrete pedestals, and loop detector vehicle sensors installed at a certain intersection approach. Successful implementation of an EE program is particularly important for ITS professionals because frequently ITS systems and electronic enforcement can be grouped together in the PUB Published by: lic's perception. PUB Published by: lic opinion surveys have shown that most people have strong opinions about EE, whether those opinions are positive or negative. Very few people aware of EE programs are neutral on the issue. A 1989 PUB Published by: lic opinion survey conducted by the Insurance Institute for Highway Safety in and around two U.S. cities with early EE speed enforcement programs revealed that 58% of the respondents approved or strongly approved of EE, 35% disapproved or strongly disapproved. Only 5% were undecided.
