Additional Modules

The modular design of ha-dispatcher enables project-specific plugins to provide additional features such as dynamic pricing schemes or map-matching.

Map Matching

map_matching_1

Map Matching based on TeleAtlas data

As part of two customer projects, a map matching module has been developed, which enables tracing a vehicle’s path based on raw GPS data.

map_matching_2

Binary Space Partitioning of road links

Based on a binary space partitioning graph shown in the above illustration, the map-matching module is able to find the appropriate road link to a GPS position. Combined with GPS bearing information and a tracing algorithm, the exact distance and topology of the used road links may be determined based on the GPS track of an On Board Unit.
