Facilitation of the Implementation of Mobile and Short Duration Maintenance Operations Guidelines (5-4174-01-1)

Recently, as part of project 0-4174, Texas Transportation Institute (TTI) researchers developed maintenance traffic control plans (TCP's) for select mobile and short duration operations, as well as guidelines for choosing whether protection vehicles (i.e., trail and shadow vehicles) are needed based on roadway type, roadway volume, and posted speed limit. The objective of this implementation project was to facilitate the adoption of these procedures by the Texas Department of Transportation districts as a means of increasing the safety of mobile and short duration maintenance operations. To do this, researchers gathered input concerning these procedures from TxDOT personnel in five TxDOT districts. Based on the input received, researchers made revisions to the draft mobile and short duration maintenance TCP's and protection vehicle guidelines. In addition, researchers created and revised color-coded maps for each district that visually depict the protection vehicle guidelines.
