Abstract
This report describes a 15-month project conducted for the Texas Department of Transportation (TxDOT) to evaluate various considerations for inclusion into the traffic signal warranting procedure. Researchers conducted several research tasks including surveys of TxDOT, other state DOTs, and city engineers. Analyses were also conducted to investigate the feasibility of incorporating heavy vehicle factors into the warranting analysis procedure. Other considerations that were addressed include accident seventy and exceptions to the warrants similar to the emergency-traffic signal. The project developed guidelines for conducting traffic signal warrant analyses. Adoption of the guidelines by the TxDOT will provide clarification of many interpretations that may be made of the language that makes up the warrants. Additionally, the guidelines will help improve the consistency with which the warrants are used.
