75 A P P E N D I X A Survey The National Cooperative Highway Research Program (NCHRP) is synthesizing state DOT use of Vehicle Probe and Cellular GPS data for Monitoring and Planning activities. The project, NCHRP 20-05/Task 51- 06, will help educate DOTs on the state of the practice and include several case-studies on how agencies are making use of this data to inform their operations and planning activities. We have selected you to take this important survey because of your leadership in the DOT, and because we believe you are likely to know the right people within your organization that could help you compile the most complete response. Below is a survey that is intended to help us learn more about current practices and uses of Probe and GPS data in your organization. The survey is short and should take about 15 minutes to complete. Before you begin the survey, please take some time to consult with others in your organization who may be using GPS and other cellular probe data. In doing so, the survey will take less time and help us synthesize the most complete information for the final report. You can also download a copy of the survey here. If your organization is already substantially invested in using vehicle probe and cellular GPS data, we may, with your permission, follow-up with limited additional questions for a possible case study, providing an opportunity to showcase you and your colleagues’ practices to a nationwide community of transportation professionals. If you have any questions or comments regarding this survey, please contact me using my information below. Regards, Michael L.
