Duhail Interchange, Doha Expressway (Qatar)

Supply, installation & maintenance of Over-height Vehicle Detection System on 3 approaches of the Duhail Interchange.

• • Each approach is equipped with the following components: Static sign indicating maximum height with flashers.
    • Static sign indicating designated exit
    • OVDS – Z Pattern Type
    • Gantry mounted full colored full matrix LED VMS
    • Pole mounted Yellow full matrix LED VMS with two strobes
    • Electronic Alarm siren installed on the pole mounted VMS
    • Road Side Controller
  • The whole system is integrated to SCATS which allows appropriate traffic signal coordination. When an over-height vehicle is detected, the traffic signal of the approach where the over-height vehicle is headed will be automatically switched to RED by SCATS, thus preventing the vehicle’s passage towards the bridge of the interchange.
  • Two (2) Pan-Tilt-Zoom Cameras installed at the Duhail Interchange are integrated into the system that provides automatic live CCTV feed on an approach where an over-height vehicle is detected. The CCTV feed is displayed at the Traffic Control Center located at the PWA (Ashghal) Tower.
  • The over-height vehicle’s driver is alerted of the impending danger by an audible sound while two (2) full matrix VMS provide visual warnings and directs the driver to the designated exit to avoid hitting the bridge on the interchange.
  • At the Traffic Control Center, an audible alarm alerts the SCATS operator that an over-height vehicle is detected. The SCATS operator then monitors the movement of the over-height vehicle until it heads to the designated exit. Once the impending danger is cleared, the SCATS operator returns the traffic signal phasing of the interchange to its normal operation.
