FINAL RESULTS OF AN EXTENSIBLE PUBLIC TRANSPORT JOURNEY PLANNING SYSTEM PROTOTYPE USING JOURNEY WEB PROTOCOLS

This research engineered and prototyped a collection of Internet-based methods, including XML, which allow electronic journey planners to remotely interrogate public transport schedule information held within compliant journey planners using a common protocol. The prototype contained journey planners covering three counties using two suppliers, and two national journey planners (rail and coach) to connect them via exchange points. The setup permitted initial trials of a local-national-local or three-leg, cross-boundary journey enquiry. The prototype journey planner software then made serial Internet requests to each system on behalf of the traveler, using a matrix of exchange points. Tests showed a range of response times between 15 and 50 seconds, an improvement from five minutes in initial research. This final report concludes that further reduction in the response time is a function of reducing the response time of the remote journey planners, making remote requests in parallel, and optimising the number of exchange points
