Our responsibility is ensuring that our work zones are safe

for daily drivers and workers of every project

​

Smart work zones allow us to use a variety of intelligent technologies

so we can better monitor roadway conditions and

communicate those conditions to drivers

Temporary Queue Detection System

7

Scenario:

    • Incoming vehicle being confronted with slowed or stopped traffic in work zone

​

Countermeasure:

  • A system with queue detector, messaging feature, and a network to link the two
  • Increase situational awareness

Temporary Speed Monitoring System

8

Scenario:

    • Excessive, unsafe speed in work zone
    • Non-uniformity of speed (high or low)

​

Countermeasure:

  • Basic system: trailer mounted radar detector with 2-digit LED message board
  • Advanced: speed compliance system with flashing blue light
  • Improve speed compliance

Scenario:

    • Construction vehicle merging to traffic stream from work zone

​

Countermeasure:

  • Truck detector, a message board and wireless communication to trigger the sign

Temporary Travel Time System

10

Scenario:

    • Motorist need travel time / delay in advance work zone

​

Countermeasure:

  • Detector throughout the work zone to calculate travel time, message board and communication links
  • Make informed decision, set realistic expectation, encourage diversion

Temporary Incident Detection and Surveillance System

11

Scenario:

    • Higher than normal incident risk in most work zones and worse impact

​

Countermeasure:

  • Speed detector, CCTV and communication links
  • Reduce the time to detect, respond and clear incidents
