Title: Methods to Prioritize Maintenance and Replacement of Aging or Obsolete ITS Infrastructure
Contact: Michael D. Fontaine

Project No.: 102685
Target Date: 06/10/2014

Many older intelligent transportation systems (ITS) have significant maintenance needs, and some “legacy” systems are becoming functionally obsolete. ITS is a relatively new addition to the overall transportation infrastucture, so agencies have  comparatively limited experience with maintaining these systems. 

The purpose of this study is to recommend to the Virginia Department of Transportation (VDOT) ways to prioritize the maintenance and replacement needs associated with the ITS infrastructure. 
This study will have two components:

1) Establishing criteria to determine if an element should be maintained, replaced or removed from the system, and

2) Developing a method for ranking and prioritizing maintenance and replacement projects. 

Information from this study will provide VDOT with the capability to make the best use of the benefits from what it spends on ITS infrastructure.
