Goals
The project is split by long term goals implemented via short term goals that could already Make a Difference ™ at the control center of an operator.
The user has an operational view of the network, this could be the diagram based rail map, a true to distance based map projected on an aerial photograph or topographic layer. The user is able to see the operational vehicles moving over the map and is able to alternate the time and speed of the simulation. The simulation displays the historic real-time data, and show both predicted and scheduled positions. The user is able to modify the network, for example to disturb a certain link in the network. The system will then generate a list of of issues that will occur due to this disruption. The disruption can be operationally solved by cancelling trips or applying a deviation.
We would need a simulation of the operational vehicle situation that is able to take in account the available schedules combined with the historic real time information. The simulation would allow aggregating the stop locations to stop areas, and the presentation of bidirectional links. The vehicles are interpolated on the links given the available intermediate points positioned by distance on the link with respect to the total distance over the link. The positioning works as percentage, hence it would also work in a system that would not use as the crow flies interconnections. The simulation should be able to handle the entire network. The simulation could select any time during the day, at any multiplier. The user should be able to skip through a day by either entering a time, or moving a time slider.
External events such an incoming radio hail should highlight a vehicle, and its position. Given that such event is triggered in real time, it is likely the dispatcher would like to have a shared view of the vehicle requesting communication. Next to looking on a map, having a streetview style photo to give the dispatcher more context of what the message might be about.
The student has on operational view of a Marey diagram. The Marey diagram consists of time vertically and horizontally the distance between stop areas. The pairs between stop area we here call stop area links, the diagram has a predefined number of stop area links visible. This could be based on complete line, or a subset of a line. For all visible links in the Marey diagram all vehicle journeys that match it are shown. Hence if a specific trip has an operational issue, it is directly visible to the student. The student is presented an historical operational disruption, and is asked what to do next. The system would simulate the decision, and the teacher could show what the dispatcher had done in his case. The system would also be able to show the best decision and score the performance of each decision.
