Abstract:A demonstration software for the routing of vehicles and for the retrieval of BRINSAP information of bridges along a route is presented. The software is demonstrated for its potential application in evaluating a proposed Bridge Load Formula. The software is implemented using a network model of the On-system roads of Tx Dot's District 12. The model was created from digitized maps and by defining node and link attributes. The definition of the bridges on the links and the nodes was accomplished by a mapping procedure and was verified using Tx Dot's Road Inventory sheets. Due to insufficient span length information in BRINSAP, implementation of the Bridge Load Formula requires determination of individual span lengths of all bridges.
