Impaired Driving Analysis

Washington College Mapping and Analysis Support to Reduce Impaired Driving for the Maryland Highway Safety Office (MHSO) and Maryland State Police (MSP)




Project Overview:

Washington College was recently awarded a grant from the Maryland Highway Safety Office to work with the Maryland State Police (MSP) to provide data and analysis to support MSP’s newly created DUI Detachment. The mission of the DUI Detachment is to reduce impaired driving in the Baltimore and D.C. metropolitan areas of Maryland. To support this effort, analysts at Washington College are using multiple data sources to develop risk projections for linear roads, or rather a linear risk terrain model, to help identify road segments that should be targeted for saturation patrols in order to reduce DUI incidents.

Grant Objectives:

  • Support the MSP DUI Detachment with analysis and mapping
  • Prepare weekly geospatial analysis reports of MSP DUI Detachment activities
  • Analyze offenders under supervision for impaired driving
  • Analyze issued tickets related to impaired driving
  • Analyze saturation patrols and DUI checkpoints data
  • Analyze reported accidents related to impaired driving
  • Web-enable geospatial data analysis results

Agencies we work with:

Maryland Highway Safety Office, Maryland State Police, Prince George’s County Police Department, Baltimore County Police Department, Howard County Police Department, Governor’s Office of Crime Control and Prevention, Maryland Department of Public Safety and Correctional Services as well as additional local law enforcement agencies.
