A list of links for observed paths, with their timing and costs, that a passenger has been observed taking. Often gained from an on-board survey or GPS data.
A path, with waypoints, timing and costs, that the passenger was observed taking. Often gained from an on-board survey or GPS data. Full observed paths with all applicable waypoints can be difficult to obtain and verify the validity of. For example, on-board surveys often use a combination of stated, revealed, and intended paths because passengers are often intercepted mid-trip. GPS data often has complete revealed data, but can be subject to GPS errors, which are most drastic in urban environments. Therefore, observed passenger paths often have a great deal of interpolation and assumptions built into them that are important to understand when using them to evaluate a model.
Trajectory of a transit vehicle as observed from automatic vehicle location (AVL) data or similar.
A list of links within passenger paths, with their timing and costs.
A list of paths, with their timing and costs.
A list of links for a predicted path set/hyperpath, with their timing and costs, that the passenger considers taking.
A list of feasible paths, with their timing and costs, that the passenger considers taking for a specific trip. In some frameworks, hyperpaths can be used to create the path choice set.
The list of links for the path a passenger is predicted to take for a specific trip, with their timing and costs.
