Cestel showcases non-invasive WIM solution for bridges

Cestel says its MkIII SiWIM technology turns any bridge into a fully automatic weigh-in-motion system without disturbing the road surface. Sensors are fixed to the underside of the bridge deck beneath up to four lanes of traffic and the system is calibrated with vehicles of known weight passing individually, in opposite directions and in various combinations depending on the road layout.

8705 Cestel says its MkIII SiWIM technology turns any bridge into a fully automatic weigh-in-motion system without disturbing the road surface.

Sensors are fixed to the underside of the bridge deck beneath up to four lanes of traffic and the system is calibrated with vehicles of known weight passing individually, in opposite directions and in various combinations depending on the road layout. Having been calibrated, an algorithm then interprets the information to determine the number, weights, speed and direction of passing vehicles and the cumulative load on the bridge deck.

The system can be configured with or without cameras and is said to be easily relocated from one bridge to another (only requiring re-calibration).

Measured gross vehicle weights (above 3.5t) are said to be within 7%, individual axles within 11% and group axles within 10%. Speed measurement are within 2% and vehicles can be divided into an unlimited number of categories.

    ITS America has raised con­cerns with the US Federal Communications Commission (FCC) over the potential use of the 5GHz band spec­trum by unlicensed national information infrastructure devices. It wants to protect the 5.9GHz band for dedicated short-range communications (DSRC)-based systems. These crucially underpin the development of connected vehicle (CV) technologies which could help slash the US’ annual tally of six million road traffic accidents and over 30,000 deaths.

    Visitors to Intertraffic will be the first to see the new Marwis mobile contactless weather information sensor from German company Lufft. Marwis can be mounted on any vehicle and provides mobile collection of road weather information including surface temperature, dew point and water film height as well as road conditions (humidity, snow, ice and frost), grip (friction) and other environmental data.

    October 17, 2014
    The latest research published by Taylor and Francis, Cycle lanes: their effect on driver passing distances in urban areas, aims to study the impact of cycle lanes on cyclist safety in terms of passing space given by overtaking vehicles. In this study, the authors, Kathryn Stewart and Adrian McHale, used a bicycle equipped with cameras to record vehicle overtakes in varying road situations to determine whether cycle lanes, colour block cycle lanes or no cycle lanes affect passing distances and cyclist st
