Work Zone Traffic Information for Drivers

The dedicated short-range communication (DSRC) traffic information system alerts drivers to traffic congestion near work zone areas. Road construction areas can cause severe traffic congestion and bring about potential hazards to drivers and increase drive times. This technology uses dedicated short-range communication to inform drivers approaching work zone areas of current travel time through the area as well as where the start of congestion is located. Such information helps drivers to make informed decisions on their desired route choice.

Increasing Efficiency of Traffic in Road Construction Areas

While a previous system using the DSRC was effective in broadcasting information to drivers, the broadcast range was limited. The new system reaches a much larger audience with enhanced broadcast abilities and is capable of handling much longer congestion coverage through the use of V2V assisted V2I communication. Information gathered by the system estimates the travel time and start of road construction traffic, which is relayed to the oncoming drivers in hopes of decreasing traffic and rerouting drivers to other paths. Drivers’ computer systems are also alerted as well so that both the driver and car know exactly what is approaching. Being able to alert the system of the car could potentially lead to automated driving assistance and presents an unexpected value to all drivers. This system is one of a kind in its use of the dedicated short-range communication technology that outperforms other Bluetooth or cellular technology.


  • Much longer broadcast range than current systems
  • Enhanced road construction traffic congestion coverage area
  • Estimates important traffic parameters such as travel time and start of work zone traffic to aid traffic management
  • Portable system allows for adaptability in dynamic environments
  • Dedicated short-range communication system
