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.

    The sheer range of variables makes it difficult to find a single algorithm to ensure a 100% standard of ANPR. David Crawford investigates new processing technology. Automatic number plate recognition (ANPR), using optical character recognition and image-processing to identify vehicles, plays key roles in traffic monitoring and law enforcement, access and parking control, electronic toll collection, vehicle security and crime deterrence. Overall, system performance is well rated, with high levels of

If there is one word that epitomises the current trend in enforcement technology then that word is consolidation: multi-function cameras, miniaturisation and combining radar and visual detection methods. One example is Turkish company Ekin Technology’s recently introduced Micro Plate is claimed to be the smallest licence plate recognition device. In addition to logging licence plate data, the system records speed, date, ti

    An impending move to free-flow charging prompted a search for automated dangerous goods identification and over-height detection systems at the Thames Crossing to the east of London. Manned toll booths are increasingly being consigned to history by the onslaught of all-electronic charging. However, a secondary function of the traditional manned plazas has been to prevent non-compliant vehicles using the facility or to tell a driver that that they need to use a specific lane or wait for an escort.
