Statewide Analysis Strategies

Missouri’s Blueprint forSafer Roadways

Missouri’s Crash Data Missouri State Highway Patrol

(MSHP) is the repository for crash records

In 2002 MSHP and MoDOT merged their crash data systems

Key Principles of the Blueprint Statewide Reduction Goal – Less

than 1000 fatalities by 2008 Targeted fatalities and severe

injuries Targeted both state and local roads Used extensive data analysis to

identify key crash reduction emphasis areas

Crash Analysis Since MoDOT and MSHP have one

common database, able to query any data field that is captured on the crash report

Statewide analysis modeled after the emphasis areas identified in AASHTO’s Strategic Highway Safety Plan
