Spatially Referenced Crash Data System for Application to Commercial Motor Vehicle Crashes

摘要

The Maryland Spatial Analysis of Crashes (MSAC) project involves the design of a prototype of a geographic information system (GIS) for the State of Maryland that has the capability providing online crash information and statistical information for commercial vehicle crashes. The system is deployed over the Internet. The system is capable of displaying crash data such as specific geographic locations, period and time of crash, crash severity including the number of fatalities, contributing fctors, and the cost per crash just to name a few. The prototype features a unique horizontal drill capability whereby the users can either drill down to narrow the scope of search or drill up to expand the scope search. The mapping, querying and reporting capabilities are integrated in MSAC.
