Dept. of TransportationUS Transportation CollectionThe Maryland Spatial Analysis of Crashes (MSAC) project involves the design of aprototype of a geographic information system (GIS) for the State of Maryland that hasthe capability of providing online crash information and statistical information forcommercial vehicle crashes. MSAC is deployed over the Internet. The system is capableof displaying crash data such as specific geographic locations, period and time of crash,crash severity including the number of fatalities, contributing factors, and the cost percrash, among others. The prototype features a unique horizontal drill capability wherebythe users can either drill down to narrow the scope of search or drill up to expand thescope of search. The mapping, querying and reporting capabilities are integrated inMSAC
