FHWAOctober 2008 History of Development
History • Early ’90’s – reduction in quantity and quality of data being collected • 1998 – AASHTO Strategic Highway Safety Plan • Management core element – improve information and decision support systems
History • 2003 – FHWA and AASHTO sponsored International Safety Data Scan • Team visited Europe and Australia • Final report and implementation plan developed • http://international.fhwa.dot.gov
History • 2004 – FHWA funded first steps of implementation plan - “White Paper” • Build upon the recommendations from the International Safety Scan • Expand the strategies for improving safety data and information systems • Provide specific action items to implement these strategies • www.tfhrc.gov/safety
Overview of Broad Strategies • Increase support for safety programs and safety information systems • Define “good inventory data” and move toward the use of performance measures • Make it easier to collect, store, and use all types of safety data. • Increase the use of safety analysis tools. • Link safety data to non-safety data.
Inventory Data & Performance Measure Strategy • Develop definitions of “good safety inventory data” • Need a companion to MMUCC • We suggested “MMIRE” – Model Minimum Inventory of Roadway Elements • Starting points – Current and expected safety inventory databases and safety analysis tools • Scope should include both existing and desired data elements (e.g., ped/bike volumes)
MMIRE Data Elements • Existing tools and data systems • HPMS • IHSDM • SafetyAnalyst • TSIMS • Project team knowledge of HSIS states’ data and HSIS research, Highway Safety Manual efforts, non-traditional safety data analyses (e.g., pedestrians, roundabouts)
MMIRE Matrix • Elements captured in working matrix • 170 total elements • Roadway Segments, Roadway Alignment, Roadway Junctions, Interchanges & Ramps • Team recommendation • Priority of each potential element (primary, secondary, do not include) • Ease of data collection • Linkage to other source • Presence in other databases/tools • HPMS, IHSDM, SafetyAnalyst, TSIMS, MMUCC
MMIRE Workshop (TR Forum 2006) • Insure review and input to MMIRE from state and local data collectors and users and safety researchers • Attendees provided: • Feedback on the adequacy of MMIRE elements and proposed priorities • Suggestions for adding/deleting elements and collection problems and solutions • Suggestions on further MMIRE implementation efforts
Final Report • Documents development process and includes working matrix • 180 data elements • www.mmire.org
