Abstract :
The author describes the development of a digital road network database for the Region of Waterloo, Ont. from National Topographic Service 1:50000 digital map files. The system was developed for use in conjunction with a positionally based emergency location code assigned to rural properties in the Region, and is being extended to other areas. Real-time dispatching and routeing of emergency service vehicles from a digital database have been demonstrated for over 10000 nodes and 13000 road segments. The database is being enhanced to incorporate a variety of attribute data which can be used by all emergency service agencies. A full set of network functions is included for dispatching, routeing network flow, simulation and training, etc. The road data can be structured to accommodate arbitrarily large networks by using an embedded hypergraph model. Other potential applications are based on use of automatic vehicle location as an onboard facility in conjunction with the database.<>
