Over-height vehicle detection system implemented on New York City Parkways

A US$4.8 million over-height vehicle detection system has just been completed on two New York City parkways in a bid to minimise truck collisions, improve road safety and protect highway infrastructure. The infrared system identifies and alerts over-height vehicles illegally using the parkway to prevent the vehicles from striking low-clearance bridges, which are found on most parkways in New York. The system was installed at four locations on the Hutchinson River Parkway in the Bronx and one location on the Grand Central Parkway in Queens.

The detection systems, developed by the 1780 New York State Department of Transportation, are part of the state’s latest effort to keep commercial vehicles off parkways and improve roadway safety across the State. Bridge strikes can result in serious accidents, significant traffic delays and damage to the bridges.

Using infrared beams, the detection system identifies an over-height vehicle illegally using a parkway, captures the vehicle’s movements on video and then posts an alert message for the driver on an electronic variable message sign, enabling the driver to leave the highway before encountering a bridge. The data and video are also sent to the Department of Transportation’s Joint Traffic Management Center so that police can assist in getting a truck safely off the roadway, or mobilise quickly if an accident occurs.

Large commercial trucks and tractor trailers are prohibited from entering parkways in New York because the roadways, built in the 1930s and 1940s, were designed for automobiles and have low bridge clearances, with some as low as seven feet.

The project has received a Platinum Award by the American Council of Engineering Companies, an organisation that honours excellence in the engineering field.

    Bosch has revealed that its driver drowsiness detection system, first introduced as a standard feature in 2010, in the new Volkswagen Passat is being fitted to the new Passat Alltrack. Fatigue and microsleep at the wheel are often the cause of serious accidents. However, the initial signs of fatigue can be detected before a critical situation arises, and the Bosch system can do this by monitoring steering movements and advising drivers to take a break in time. The required information is provided either by

    Someone once likened predicting the future to ‘nailing a jelly to the wall’. With ITS, C-ITS and V2X technology progressing at such a pace, predicting the future is more akin to trying to nail three jellies to the wall – but only having one nail. And yet with roadways having a lifetime measured in decades, that is exactly what highway engineers and traffic planners are expected to do. Fortunately, New Hampshire DoT (NHDoT) believes its technological advances may be able to provide a solution. The Central Ne
