Cisco’s low-cost fibre optic solution for traffic monitoring

1028 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 fibre optic cables run in lengths of up to 80km and are divided (virtually) into five to 15 metre sections for detection purposes and it is said to be far cheaper and less disruptive to install and maintain than its traditional counterpart.

According to the company’s Niels van den Berg, the Dutch authorities have proved the new system’s accuracy by comparing it with the current loop-based results.

    Gardasoft liquid lens provides faster focus and better images
    Gardasoft is demonstrating how to capture high-quality images of fast-moving vehicles using an innovative liquid lens concept. This, the company says, provides significant performance benefits over traditional, fixed-focus lenses. Many ITS applications require vision systems which can cope with widely varying distances between object and camera. A challenge in the ITS space is the high speeds which can be encountered, particularly in free-flowing traffic. Gardasoft’s approach features a shape-changing

    Japan to equip 5G base stations on traffic lights
    The Government of Japan is to install 5G wireless communications base stations on traffic signals nationwide by 2025. A report by The Japan News says the project is expected to reduce costs for telecommunications service providers. As part of the project, traffic signals will be equipped with devices to measure the amount of traffic. The information sent from the stations to the vehicles is expected to support autonomous driving. Japan is not the only company looking to harness the potential of 5G. In F

    UK man refuses to take down fake speed camera on A1 road
    A 72-year-old man living beside a major UK road has refused to take down a replica speed camera. The BBC report says Mike Lacey built the fake camera for £40 using drainpipe and guttering to slow drivers passing his house next to the A1 in Beeston, Bedfordshire. Lacey says authorities have asked him to remove the structure as it was distracting for drivers. The village is divided by a dual-carriageway with a speed limit of 50mph.
