Sign Retroreflectivity

The Jackson MPO’s Sign Retroreflectivity Program was developed to assist Local Public Agencies (LPA’s) in the MPO’s Urbanized Area Planning Boundary in meeting federal regulations as it relates to traffic signs meeting minimum retroreflectivity standards. The Jackson MPO provides a sign inventory software that is available, at no cost, to each LPA for managing and inventorying all roadway signage in their respective jurisdictions. This software, iTrac Signs, is a web-based traffic sign inventory system that assists LPA’s in tracking the locations and condition of traffic signs in their area. 

The MPO also provides to each LPA the use of a Road Vista 922 sign retroreflectometer.  A sign retroreflectometer is a hand held device used to measure the retroreflectivity levels of traffic signs. This device can also be used to collect Global Positioning System (GPS) coordinates that can be used to map out the locations of all signs in an LPA’s jurisdictional boundaries.  The retroreflectometers are made available to the LPA’s on a lease system, at no cost to the LPA.

Jackson MPO staff is available to each LPA in the MPO Urbanized Area on an as needed basis for technical assistance and training purposes as it relates to use of the sign retroflectometers and iTrac Signs software program.
