A rule-based procedure reconstructs vehicle trajectories from bus smart card transaction data. It takes as input data a series of tap-in and tap-out transactions, geo-located to bus stops, recording the card identifier, bus line and direction, vehicle identifier and transaction time. Furthermore, it requires a network description and transit routes and schedule information compliant with the MATSim input format. The process produces a series of “events” compliant with the MATSim format; these are time-stamped atomic units of information that describe the movements of the buses through the network, their dwell operations at stops, together with passenger boardings and alightings. MATSim-compliant analysis tools are then capable of visualising bus movements and perform analyses of ridership, in-vehicle travel times, transfer times and more. Multinomial regression models are derived to describe headway and its variation. Variables tested in the regression analyses include system-wide congestion-levels, taken from a macroscopic fundamental diagram of passenger accumulation and output. A simple method to derive these quantities from the smartcard data is shown, and accumulation is also compared against expected steady-state values calculated using Little’s Law. Further application of the resulting trajectory data includes a realistic model of travel time between transit stops during the course of the day in a fast, simplified transit simulation, and to drive a travel time and waiting time-aware, dynamic transit router Show more
