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

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 a linear risk terrain model, to help identify road segments that should be targeted for saturation patrols in order to reduce DUI incidents.

What We Do

The goal of this collaboration between Washington College’s GIS Lab and the Maryland State Police is to provide the MSP and the MSHO with weekly geospatial analysis reports to help aid the newly created DUI Detachment unit. In addition to working with the MSP, we receive data from a variety of law enforcement agencies throughout the state, in order to create the most effective analyses possible. It is our goal to better enable the Maryland State Police to reduce impaired driving in the state of Maryland.

Our Partners

In order to best understand DUI incidents, our GIS Analysts work in conjunction with members of the 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. These agencies provide us with information on the incidences of DUI in their jurisdictions, and we create maps of those incidences that we then provide to the Maryland State Police.

Our Data

We use a variety of data sets to build the most complete analysis possible, to make Maryland’s roads safer. Among the sets we use are: ETIX (the Electronic Traffic Information eXchange, which partners with 97 separate agencies); Crash Data from the State Highway Administration; Liquor License/Bar database; Parole and Probation reports; and Alcohol Incident Reports. We take the information contained in these data sets to build a visual representation of crash sites and the factors involved in them.
