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.

    Hybrid communications to variable message signs increase resilience to natural disasters and enable deployment in remote areas, as Alan Allegretto explains. Variable Message Signs (VMSs) are a common sight and a well-proven means to improve public safety on our roads and highways. ITS professionals rank the VMS as second only to interoperable radios as the most important technology to improve effectiveness during emergency incidents and evacuations. Ironically, however, current systems suffer from one criti

    Bob Lees, co-founder of Diamond Consulting Services, on why the loop detector just refuses to go away. The more strident proponents of newer and emergent detection technologies are quick to highlight what they see as the disadvantages, and hence the imminent passing, of the humble inductive loop. The more prosaic will acknowledge that loops continue to have a part to play in traffic management, falling back on the assertion that it is all a question of application. And yet year after year the loop, despite

  • Tolling systems - interoperability is key

    Is US tolling as fragmented and divided as some would have you believe? And are the technology suppliers so very entrenched? ITS International spoke to the market's leading suppliers. A few years back, the prevalent view was that the North American tolling market was characterised by fragmented, proprietary solutions, each existing in splendid isolation. The reality is that a combination of pragmatism and good old market forces have seen some concerted moves made towards interoperability in many areas.
