Geographic Information Systems

Maryland Highway Safety Office

GIS is a versatile and highly adaptive technology that can be applied to virtually any field. From history to biology, from medicine to criminology, GIS makes data come to life, and we can help you find ways to make GIS work for you.


Washington College’s Crime Mapping and Analysis Program (CMAP) were awarded two grants from the Maryland Highway Safety Office (MHSO) to provide impaired driving analysis and traffic records improvement. To support both of these efforts, teams of professional staff and students were assembled to carry out each initiative. Collaboration with law enforcement, government agencies, and other universities has been essential for providing the level of support required for these grants. 

Impaired Driving Analysis

Washington College was awarded a grant to work with MHSO and the Maryland State Police (MSP) to provide data and analysis to support MSP’s newly created DUI detachment unit, SPIDRE Team. The mission of the SPIDRE Team is to reduce impaired driving in the Baltimore and D.C. metropolitan areas of Maryland. To support this effort, analysts at Washington College are utilizing multiple data sources in order to develop a linear risk terrain model; the goal of this model is to help identify road segments that should be targeted for saturation patrols in order to reduce DUI incidents.

Washington College supports MSP and MHSO by providing these agencies with monthly geospatial analysis reports to help aid the newly created SPIDRE Team. In addition to working with MSP, Washington College receives data from a variety of law enforcement agencies throughout the state in order to create the most effective analyses possible. Our analysts provide quarterly alcohol-related geospatial maps for Anne Arundel, Baltimore, Montgomery, and Prince George’s counties. It is the goal of the Washington College GIS Program to better enable the Maryland State Police to reduce impaired driving in the state of Maryland.

In order to best understand DUI incidents, our 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, Anne Arundel County Police Department, Maryland Department of Public Safety and Correctional Services, as well as additional law enforcement agencies.

Traffic Records Improvement 

Washington College was awarded a grant to provide support to the Maryland Highway Safety Office (MHSO) to improve accessibility of traffic safety data and to improve statewide traffic safety data completeness and accuracy. The program focuses on three main objectives: provide MHSO with maps of crash data and citation data for use in program planning and evaluation by MHSO and their partners; provide training to traffic safety professionals on the use of GIS analytical tools; and increase the completeness and accuracy of crash data as well as improve accuracy of citation data. Accessibility will be achieved not only through hard copy maps, the online map, and training, but through presentations at meetings and webinars.

Washington College has been working closely with Baltimore City to improve and complete the location information of crashes in the city. Baltimore City does not use SHA’s roadway inventory, so the best way to locate their crashes is to provide an x/y location. Once these crashes are collected and updated, Washington College will work with SHA to update the statewide crash file with these completed crash records. Most law enforcement agencies do not have access to all of the data used for this project (crashes, citations, etc.), or the analysts to download, update, correct, and map/analyze the data, which is essential in developing mapping or analysis products. Washington College is able to coordinate all of the data collection, storage, and distribution of datasets needed for law enforcement to make data driven decisions on determining locations for patrols.

Data Collection and Improvement 

Various agencies provide Washington College with datasets including: ETIX/Datbak citation data, crash reports, crash data from the State Highway Administration (SHA)/ACRS which includes aggressive, impaired, and etc., and liquor license information. We take the information contained in these datasets to build a visual representation of crash areas and the factors involved in them.
