Lusail Expressway Project - Qatar

Client: Public Works Authority – Ashghal
Consultant: CDM Smith
Contractor: Hyundai Engineering & Construction, Co. Ltd.
Subcontractor: Traffic Tech (Gulf) W.L.L.

Lusail Expressway is one of the biggest among 30 road projects to be developed as part of Qatar’s seven-year expressway programme initiated in 2010 to connect people and places across the city of Doha and Qatar through 900km of new roads, involving a number of underpasses, flyovers and multi-level interchanges.

The project will involve 5.3km of four-lane highway in both directions and three major interchanges in Northern Doha, namely the Al Wahda Interchange, the Onaiza Interchange and the Pearl Interchange.

The expressway will also have two service lanes in the multi-level interchange areas, and include a complex network of tunnels, flyovers and junctions in order to meet the future traffic demands by providing easy and quick connectivity.

In addition, the project also involves the construction of two new multi-lane canal crossing bridges.

Traffic Tech has developed detailed design of:
    • Lusail Expressway Traffic Control Center (TCC)
    • Intelligent Transportation System (ITS) equipment on open road and tunnels
    • Advanced Traffic Management System (ATMS) as one system that would monitor and control traffic on the entire length of Lusail Expressway (both open/surface road and tunnels).

The main purpose of the ITS work for Lusail Expressway is to equip it with traffic management system that provides drivers with warnings, manage speed limits, provide drivers with appropriate travel time and re-routing information, automated responses to traffic conditions, traffic density, incidents, special events and maintenance work.

This Lusail Expressway Project is equipped with highly advanced ITS components including:
    • Magnetometer Detection Systems (MDS)
    • Closed Circuit TV Cameras (CCTV)
    • License Plate Recognition (LPR) System
    • Automatic Incident detection (AID) System
    • Dynamic Message Signs (DMS)
    • Lane Control Signs (LCS)
    • Over-Height Vehicle Detection System (OVDS)
    • Weigh In Motion (WIM)
    • Emergency Roadside Telephone System (ERT)
    • Radio rebroadcasting System (RRS)
    • Public Address System (PA)
    • Road Weather Information System (RWIS)
    • Roadside Controllers & Communications System
    • Control Room

Qatar Traffic Control Centre

Signalizing Roundabouts

Traffic Tech has developed a unique phasing and timing system for signalizing roundabouts and have so far signalized more than 20 roundabouts in Qatar.

Emergency Vehicle Preemption System (EVPS) - Qatar

Traffic Tech (Gulf) designed and built Qatar’s first fully integrated Emergency Vehicle Preemption System (EVPS), a GPS based system that allows emergency vehicles equipped with a preemption emitter to get priority on signalized intersections / roundabouts.

Traffic Tech (Gulf) installed 100 EVPS at various junctions across Qatar, while 51 ambulances from HMC and 7 vehicles from the Civil Defence are equipped with preemption emitters. The EVPS is integrated into Doha’s SCATS Urban Traffic Control System, and is monitored from the Ashghal RMC.

System Includes:

    • Installation of GPS based EVPS out-station equipments.
    • Installation EVPS preemption emitter equipment on emergency vehicles.

Over-height Vehicle Detection System (OVDS) Projects

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.
