49 NCHRP TOPIC 44-05 SURVEY QUESTIONNAIREâFOR STATE AGENCIES The Transportation Research Board (TRB) is preparing a synthesis on Roadway, Traffic and Crash Data Interoperability between Local and State Agencies Relative to Roadway Safety (Topic 44-05). This is being done for NCHRP, under the sponsorship of the American Association of State Highway and Transportation Officials (AASHTO), in cooperation with the Federal Highway Administration (FHWA). In order to utilize the evolving safety analysis tools and methodologies to more efficiently and effectively address road- way safety issues and meet the MAP-21 requirements, agencies will be looking to improve their data for safetyâparticularly roadway, traffic, and crash dataâon all public roads. The largest challenge will be the collection, storage, maintenance, and integration of safety data for local (non-state) maintained roadways. As agencies move toward improving the quality of data on the local roads, they will be looking for examples from other agencies that have been successful in doing so. The project team is familiar with the recent FHWA Roadway Safety Data Capabilities Assessment; the questions in this questionnaire will not duplicate, but rather expand upon the Capabilities Assessment effort. For any multiple choice questions, please choose the answers that best represent your state practices. This questionnaire is being sent to U.S. state departments of transportation. Your cooperation in completing the question- naire will ensure the success of this effort. If you are not the appropriate person at your agency to complete this questionnaire, please forward it to the correct person. Thank you very much for your time and expertise. Please complete and submit this survey by 03/08/2013. We estimate that it should take less than 30 minutes to complete. If you have any questions, please contact our Principal Investigator Nancy Lefler by phone: (919) 334-5604 or e-mail: nlefler@ vhb.com. Any supporting materials can be sent directly to Nancy Lefler by e-mail or at the postal address shown at the end of the survey. The following definitions are used in this questionnaire: Crash data: Data contained in the crash reports submitted after a collision (e.g., date, time, location, crash type, severity). CurvesâData pertaining to the physical and location attributes of vertical and horizontal curves (e.g., curve degree, curve radius, percent of gradient). IntersectionsâData pertaining to the physical and locational attributes of intersections, including general intersection descriptors (e.g., number of legs, traffic control) and intersection approach descriptors (e.g., number of right turn lanes, length of right turn lanes). Intersection turning movement countsâData pertaining to the turning movements at intersections (e.g., left turn volume, right turn volume). Local roads: Non-state maintained roadways. MAP-21: Moving Ahead for Progress in the 21st Century transportation legislation (http://www.fhwa.dot.gov/map21). MAP-21 data requirements: âAs part of the state highway safety improvement program, a state shallâ(A) have in place a safety data system with the ability to perform safety problem identification and countermeasure analysisâ(i) to improve the timeliness, accuracy, completeness, uniformity, integration, and accessibility of the safety data on all public roads, including non-state owned public roads and roads on tribal land in the state; The term âsafety dataâ means crash, roadway, and traffic data on a public roadâ (MAP-21 §1112; 23 USC 130 and 148).
