Traffic Control Device Analysis, Testing, and Evaluation Program

This project will provide TxDOT a mechanism to quickly and effectively conduct high priority evaluations of traffic control devices (TCD) including human performance, vehicle technology performance (for sensors used in new vehicles), safety effects, policies, and specifications. The TCD issues to be evaluated in this project may represent new devices or technologies, new applications of an existing device or technology, traffic control device material performance, changes in TxDOT’s practices regarding a TCD, or other TCD related needs. Examples of various evaluations include human factors, machine vision performance, safety effects, visibility assessments, and cost/benefit analyses. The activities conducted through this project will support the development of TCD related policy, standards, guidelines, handbooks, and training. This project is intended to support TxDOT’s District needs primarily the Traffic Operations, Maintenance, and Construction Divisions, but also the Engineering Divisions. In each year of the project, TCD issues will be identified and prioritized for investigation. The selected issues will be evaluated and addressed with a separate work plan, and the results will be presented in with technical memorandums that will include findings and recommendations that can support the implementation of the new guidelines or policy, as appropriate.
