摘要

Presented in this paper is a major step towards an innovative solution of GIS road networkdatabases updating which moves away from existing traditional methods where vendors of road networkdatabases go through the time consuming and logistically challenging process of driving along roads toregister changes or GIS road network update methods that are exclusively tied to remote sensing images.Our proposed road database update solution would allow users of GIS road network dependentapplications (e.g. in-car navigation system) to passively collect characteristics of any “unknown route”(roads not in the database) on behalf of the provider. These data are transferred back to the provider andinputted into an artificial neural net (ANN) which decides, along with similar track data provided by otherservice users, whether to automatically update (add) the “unknown road” to the road database onprobation allowing subsequent users to see the road on their system and use it if need be. At a later stagewhen there is enough certainty on road geometry and other characteristics the probationary flag could belifted and permanently added to the road network database. Towards this novel approach we mimickedtwo journey scenarios covering two test sites and aimed to group the road segments from the journey intotheir respective road types using the snap-drift neural network (SDNN). The performance of the SDNN ispresented and its potential in the proposed solution is investigated.
