Detection of Out-of-gauge and Prohibited Vehicles, and driving violation behaviour in Government Road Tunnels

I&T Wish Detection of Out-of-gauge and Prohibited Vehicles, and driving violation behaviour in Government Road Tunnels
(REF: W-0560)
Matched I&T Solution
Trial Project
Summary and Challenges
  • In accordance with Cap. 368A, 498B and 594A, vehicles conveying specified dangerous goods (DG Goods) are prohibited. Additionally, out-of-gauge vehicle (e.g. over-width, over-length, over-height and over-weight) without a permit shall be refused to travel in Government road tunnels. Drivers should drive in compliance with the lane control use signals. Drivers of heavy vehicles and specific vehicle classes should drive on specified traffic lanes. Some drivers may not aware the restrictions applied to their vehicle or may not notice the regulatory traffic signs and signals in the tunnel area.
  • Currently, tunnel staff can only identify out-of-gauge vehicles (except over-height vehicle), passage of prohibited vehicles and driving violation behaviour through CCTV monitoring, road side visual inspection and sample checking of suspected vehicles. Hence, there is a need to improve the situation.
Expected Outcome
  • The system should apply any appropriate technologies (e.g. video analytic by visual camera, point-cloud analytic by Lidar, Internet of things sensor and electronic sensor etc., with or without road side equipment) to detect the following scenarios:
    1. Vehicles constructed for conveying DG Goods (Classes 1, 2, 3 and 3A);
    2. Over-weight Vehicles with/ without causing traffic interruption;
    3. Over-width Vehicles with/ without causing traffic interruption;
    4. Over-length vehicles with/ without causing traffic interruption;
    5. Heavy vehicles and specified vehicle class on outer most traffic lane in tunnel tube ;and
    6. Vehicle movements not match with the prevailing lane control signal.
  • The system should response the following actions when the scenario above happen:
    1. automatic generate a visual alert to notice the driver that the ban applied to their vehicle;
    2. automatic capture the concerned image and/or video; and
    3. automatic generate a message to the registered email address & dedicated monitoring workstation; Meanwhile, the system should have a centralised management platform, field equipment (if any), both with permanent software licenses. The field requirement can be powered on with portable power station for 7-day 24-hour operation.
Expected Trial Duration 12-month
