Implementing a Minimum Path Finder to Favor Right Driving Behaviors in the City: Integrating Prolog Rules on the Web Server to Flash Builder Action Scripts on the Mobiles

Currently, the minimum time path-finder software packages reside on the user navigators or on a main urban server, but compute the minimum paths using statistical travel times. However, such paths are not always the best ones and, consequently, a software is envisaged which uses the current road travel times. Since such navigational and monitoring software may cause a very high server load, the paper aims at illustrating an alternative solution obtained with driver mobiles able to compute both the services suitable for the drivers and the best current paths to reach them, with a limited intervention of the server. In particular, a distributed computing scheme consisting of a navigational and monitoring software resident on the server integrated with a navigational package implemented on the mobiles is presented. A case study clarifies how the proposed solution helps both drivers and pedestrians.
