Physically consistent map matching
Proceedings of the 30th International Conference on Advances in Geographic Information Systems, 2022 An important data source for traffic analysis is GPS trajectory data. However, due to measurement inaccuracies, such data does not necessarily align well with data describing the road network. Hence, GPS data typically needs to be aligned with the road network before further analysis can take place; this process is called map matching.
