摘要：	This report presents findings on the activities conducted in the Traffic Control Device Evaluation Program during the 2017 fiscal year. The research on sponsored changeable message signs (continued from the previous year) was terminated by the Federal Highway Administration. Also continued from the previous year, the update for determining time requirements for traffic signal preemption at highway-railroad grade crossings was completed. New efforts included a focus on wrong-way driving mitigation efforts throughout Texas and a safety evaluation of wet-weather pavement markings in Texas. The final activity was an effort to develop a method to compute roadway grade from streaming data.
