Italian exhibitor Iwim is exhibiting a new fibre-optic based weigh-in-motion system called the 50_10. Certified to OIML R134 class 10, the system can weigh heavy vehicles with up to five axles at speeds between five and 50km/h (weigh readouts of vehicles travelling above 50km/h are not OIML certified).

Italian exhibitor 8688 Iwim is exhibiting a new fibre-optic based weigh-in-motion system called the 50_10. Certified to OIML R134 class 10, the system can weigh heavy vehicles with up to five axles at speeds between five and 50km/h (weigh readouts of vehicles travelling above 50km/h are not OIML certified).
According to the company, the use of fibre optic technology means the system is not affected by electromagnetic interference or temperature variations, there are no electric cables running to the installation and maintenance requirements are minimal. Installing the 151 x 62cm plates require a 7cm evacuation and the maximum weight limit is 20tonnes per axle.
Readouts include vehicle weight, type, class, speed, axle count, axle weights, twin tyre axles, axle width and axle spacing. Potential uses include enforcement, traffic monitoring statistics and both toll and ‘polluter pays’ management.
Cisco’s display focuses on a novel way of detecting traffic speeds, congestion and incidents without the use of loops. The company is using a fibre optic cable positioned alongside the road and down which it shines a light. Vibration created by passing vehicles create vibration which disrupts the passage of the light. Cisco has developed algorithms that can translate these disruptions to determine what type of vehicle is passing, in which direction, the lane it is using and the speed it is travelling. The
