TMP Implementation Performance Performance Performance monitoring Performance monitoring Worksite trailers Worksite trailers Travel time Travel time Queues Queues Cameras / Detectors Cameras / Detectors Crashes Crashes How much did accidents decrease because of mitigation measures and comparable projects How much did accidents decrease because of mitigation measures and comparable projects Did accident severity decrease Did accident severity decrease Measurements versus expectations Measurements versus expectations How did actual measured delay compare with expected delay (travel time, queues) How did actual measured delay compare with expected delay (travel time, queues) Project documentation Project documentation

TMP Lessons Learned A TMP template was created to assist project development staff with TMP submittals A TMP template was created to assist project development staff with TMP submittals Uniformity Uniformity Critical Focus Area Critical Focus Area TMP reviews are now conducted as needed versus at pre-determined dates TMP reviews are now conducted as needed versus at pre-determined dates Less Time Crunch Less Time Crunch Better Quality Better Quality Better Use of Staff Resources Better Use of Staff Resources Faster Response for Project Offices Faster Response for Project Offices

TMP Lessons Learned Public involvement in the TMP development is critical Public involvement in the TMP development is critical Crash Analysis Crash Analysis Accurate Traffic Data Accurate Traffic Data
