Bus link speed is an essential input for accurate estimation of arrival times for providing reliable service information to passengers. The speed data generated by the Global Positioning System (GPS) units affixed on buses have created an opportunity to derive reliable bus link speeds. To use GPS data, a critical requirement is to match the related positional data precisely on the respective link of its route. This research focuses on a post-processing technique for map matching for GPS data on a digital map with the assistance of Geographic Information Systems (GIS). The results from the GIS-based proposed model shows its ability to perform the map matching within a reasonably short processing time of 0.387 milliseconds per GPS observation. Moreover, the average hourly speeds of buses operating on a defined link were calculated with the developed algorithm and compared for verification purposes.
