BEST PRACTICE:

J2−3: Work Zone ITS for Traveler Information

DESCRIPTION:

Work Zone intelligent transportation system (ITS) technologies are sometimes implemented in work zones where permanent systems are not located to provide real time work zone information. These portable work zone systems are easily deployed and can provide "real time" road side travel information, information for traffic management (i.e., dynamic lane and detour routing) as well as capturing work zone speed and volume data for performance driven mobility metrics. These systems can be stand alone or incorporated into a traffic management center.

REASON(S) FOR ADOPTING:

To provide the motoring public with "real time" work zone information to improve both mobility and safety of motorists and construction workers.

PRIMARY BENEFIT(S):

Reduction of congestion associated with lane closures.
Reduction/elimination of rear−end crashes and fatal crashes due to excessive queuing.
More reliable and accurate en−route travel information.
Reduction of "road rage" for smoother, safer traffic flow through work zones.
Improved communication with the motoring public resulting in a more positive image of NCDOT.
Real time, credible information resulting in better compliance with suggested traveler actions.

MOST APPLICABLE LOCATION(S)/PROJECT(S):

Each project needs to be evaluated before any system is selected and deployed. The work zone traffic problems need to be identified and understood prior to implementing any system.

RELATED BEST PRACTICE(S):
Portable ITS Technology for Work Zone Traffic Management (Practice J1−3)
Providing Real−Time Traffic Information via Changeable Message Signs (Practice J2−2)
