Module Crash Data Collection and Uses Describe the process by which crash data are collected and used in road safety management.

Module Major Topics Importance of Accurate Data Data Collection Process Data Improvement Strategies Use of Safety Data in Road Safety Management

Module Crash Data Accuracy Case Study 60% of rural crashes coded to the zero milepost 81% of cross roads were missing 1/3 of all crashes missing location data Implications HSIP HSP CVSP SHSP

Module The “Torturous Path” of Crash Data Collection Crash Occurs Crash Report Completed Data Recorded in Database Crash Data Transferred to State Database Data Analyzed and Disseminated

Module Data Deficiencies Integration Accessibility Timeliness Accuracy Completeness Uniformity (or consistency)

Module Overcoming Data Deficiencies Training and Education Law enforcement officers Court officials and adjudicators Crash Report System Administrators Update or Review Crash Report Form

Module Overcoming Deficiencies (cont.) Technology (electronic collection, linkage, location identification, etc.) Policies and Procedures Collaboration (i.e., TRCC)

Module Electronic Reporting Systems Traffic and Criminal Software (TraCS) Crossroads Traffic Collision Database Mobile Capture and Reporting System (MCRS)

Module § 408 Grant Requirements First year grant TRCC Multi-year strategic plan Subsequent year grant Traffic records assessment TRCC Multi-year plan Grant funding specifications Measurable progress

Module NHTSA/State Partnership Traffic Records Program Needs Assessment Compare a state traffic safety program with current guidelines Report on the strengths and weaknesses of core systems Traffic Safety Information System Strategic Plan Strategic action plan to address system deficiencies – “living document” Encourage statewide integration of systems and resources

Module MMUCC Data Elements Crash Vehicle Collected - Collected at the scene and recorded onto crash report  Derived - Generated from computerized crash data  Linked – Linked to injury, driver history, vehicle registration, roadway inventory, or other data files. Person Roadway

Module Data Uses for Road Safety Management Use of Data Political Agendas Engineering Judgment Conventional Wisdom

Module The Benefits of Using Data Crash Trends High Crash Locations High Risk Groups Contributing Factors Program Evaluation Q: Is crashes per VMT a fair comparison among states? What does it imply that states can/should do to lower their rates?

Module High Crash Locations Number of Crashes Severity of Crashes Exposure, e.g., Volume of Traffic Contributing Factors Q: can you think of anything else? Hint: compare performance, cost?
