Colas’s Yellow Project warns highway teams of collision risk

Colas’s Yellow Project has been developed with Aximum Electronic Products - a Colas Group Company - and software experts Foxstream. The system uses thermal imaging and video analytics to detect and classify approaching vehicles into “threat categories”. It identifies those that pose the greatest collision risk with a highway works vehicle or nearby workers. The thermal camera is mounted at height on the rear of a works or emergency vehicle and performs in both dark conditions and full sunlight. It does not

Project Yellow uses a rear-mounted thermal imaging camera

184 Colas’s Yellow Project has been developed with 164 Aximum Electronic Products - a Colas Group Company - and software experts Foxstream. The system uses thermal imaging and video analytics to detect and classify approaching vehicles into “threat categories”. It identifies those that pose the greatest collision risk with a highway works vehicle or nearby workers.

The thermal camera is mounted at height on the rear of a works or emergency vehicle and performs in both dark conditions and full sunlight. It does not suffer from false alarms caused by pixel shifting, as can occur with an optical camera analytic system, particularly at night. When a vehicle that poses a collision risk is detected by the analytics system, an audible and visual warning is sounded and additional or amended vehicle lighting can be initiated.

In addition, a wireless alarm is provided for workers undertaking works on foot away from their vehicle to ensure they are immediately aware of a high-collision risk scenario.

The system is equipped with a GPS and Internet of Things connectivity solution for real-time monitoring of the vehicle’s position and for directly uploading data to the Datex II traffic data interface. This allows satellite navigation manufacturers to use this information to warn road users of the location of the workforce. Highways workers can select a “detection area” to mirror the road geometry and lane width when they arrive on site. This ensures that the system is used on an infinite range of curves and elevation changes while preventing false alarms.

    When a vital fiber-optic cable was cut during construction work in Germany, the impact was huge. There were telecom disruptions affecting the greater Frankfurt area, all departures and landings at Frankfurt Airport were suspended, and Lufthansa’s global IT system crashed. Leica Geosystems says it is vital to put in place “strategies to protect people, equipment, and assets… and to emphasise the crucial role digital solutions play in ensuring safety.”

    Good, readable analysis of road surfaces to ensure sufficient maintenance funding is an essential part of asset management. The technical side of ensuring a good road surface is integral to maintaining safe, superior highway infrastructure. But securing sufficient government funding for such work – repairs and new-build – based on the current road surface is also essential. To evaluate road conditions and structure for such a business case, one UK local council turned to software provider Yotta.

    UK contractor Eurovia Surfacing and Sims Milling, based near London, are trialling an automatic braking system that could save the lives of workers and pedestrians. The Banksman Auto Braking radar system is designed to remove the risk of accidents while a vehicle is reversing, with 100% accuracy at detecting objects. The system - provided by Vision Techniques – emits low-energy microwaves from a unit mounted at the rear of the vehicle. If an obstruction or hazard is detected then the system will automatica
