GPS-Based Road Pricing is a system that consists of all components required for running and experimenting with large scale real-world GPS-based road pricing. The system consists of an Android app, a web application, a server, and four databases. The Android app performs online road pricing calculations and displays the cost to the driver and reports it to the server. The web application displays specific information on the road pricing costs. The server handles requests from the Android app and web application, and stores and retrieves data from the appropriate databases.

Field trials are performed to showcase and illustrate the accuracy of the complete functioning road pricing system. Privacy of the users is handled by encrypting all data traffic and storing privacy-sensitive information separately. The costs of operating the road pricing system is minimized by using a novel message format. The system is able to scale to millions of users because of the low data costs and because calculations are performed on the mobile client.
