Maryland Crash Data

Crash Data Summary: Crash Data Summary Reports are based on data from the statewide police crash report database (ACRS), processed by the MDOT-State Highway Administration, and provide detailed aggregate information on motor vehicle crashes (overall, injury, and fatal) as well as jurisdiction-level occurrences.

Crash/Crime Clocks: The Crime/Crash Clocks represent the annual ratio of crime and motor vehicle crashes to fixed time intervals (sources: Maryland State Police Uniform Crime Report and crash data from the MDOT-State Highway Administration which maintains a database derived from crash reports maintained by the Maryland State Police).

Problem IDs: Annually produced by the Maryland Highway Safety Office and the University of Maryland, Baltimore’s National Study Center, the Problem Identification Reports examine recent crash and traffic violation trend data at the state and jurisdictional levels to understand the scope of Maryland’s traffic safety problems and causal factors, particularly behavioral causes as categorized by emphasis areas in the statewide Strategic Highway Safety Plan (SHSP).

Safety Equipment Use Summaries: Safety Equipment Use Summaries are based on crash investigation data from the Maryland State Police Automated Crash Reporting System (ACRS), and are aggregated from a query on the Safety Equipment Used field for Drivers and Occupants, excluding any non-motorists, motorcyclists, mopeds, or ATVs. For the years 2015 and later, unrestrained occupants are summarized by a query of “None” for Safety Equipment Used. Prior to 2015, “Air Bag Only” was included in the query.
