2. Problem and Motivation London Hopper Colloquium 2014 Phase 1: Literature Review The aim of the EsCORT project is to develop a passenger rail journey planner capable of responding dynamically to timetable changes. The National Rail Enquiries website is the state-of-the-art, but it is not very responsive to disruption, and is occasionally incorrect even in relation to a static timetable. The ability to cover individual needs or preferences, either by stipulation or automated learning, would be valuable. Figure 1. Microcalcifications 0.2-0.5 mm. There was no mention in the published literature of an app that plans passenger rail journeys, then responds to unforeseen disruptions by alerting the passenger and offering an adjusted itinerary. Therefore the development of such an app would be timely, filling a gap in the market.

3. Phase 2: Mathematical Modelling and Exploration of Computational Intelligence (CI) Options London Hopper Colloquium 2014 The next stage is to investigate journey planning algorithms to drive the app. Firstly, the extent to which solutions may be arrived at deductively through mathematical modelling is being explored. The relevant field of mathematics here is graph theory. Complexity theory is also highly pertinent; it is anticipated that any mathematical model produced will be far too computationally complex to be incorporated into usable software, thus justifying the use of CI.
