Differentiating between cars that stop and those that don’t

The addition of Detect on Stop (DOS) technology to EMX’s Ultraloop range of vehicle detectors, means the system only triggers when a vehicle stops for at least one second over the loop. It ignores cross-traffic and vehicles that keep moving, enabling parking exit gates to stay closed.

The addition of Detect on Stop (DOS) technology to 8229 EMX’s Ultraloop range of vehicle detectors, means the system only triggers when a vehicle stops for at least one second over the loop. It ignores cross-traffic and vehicles that keep moving, enabling parking exit gates to stay closed.

The Ultraloop ULT-PLG vehicle loop detector is compatible with a wide variety of gate operators and is said to combine small size with full-featured functionality in a plug-in module. It provides a solid-state output indicating vehicle presence while the second output can be used for presence, loop fault or pulse on entry/pulse on exit. The detector provides options for automatic sensitivity boost (ASB), delay, fail-safe/fail-secure and infinite and normal (5 minutes) presence.

    Although urban traffic control and parking management are inextricably linked in so many ways, there remain fundamental differences which undermine closer integration. Car parking guidance systems can have a significant, positive impact on congestion in town and city centres, however conflicting business models still stand in the way of the more profound integration of car parking management and Urban Traffic Control (UTC) systems.

    Beginning in the 1990s, Oregon was one of the first US states to use weigh-in-motion scales and transponder-based systems to enable trucks to avoid having to stop at weigh stations. Its Green Light preclearance system soon became a model for similar deployments throughout the country. Today, Green Light annually weighs and screens 1.6 million trucks as they approach 21 Oregon weigh stations and it preclears 1.5 million of them.
