- Travel times using any combination of three transport modes: foot, bicycle, and public transport.
- Ratios of multi-modal times to equivalent travel times in private automobile, including local infrastructure-specific estimates of time delays due to parking.
- A representation of the local street network, in
osmdata_scformat, potentially including elevation data to accommodate effects of incline on pedestrian and bicycle travel times. - A GTFS (General Transit Feed Specification)-format data file of public transport data for the study city or location.
The following parameters need to be specified:
- Name of city - used to name locally-cached files formed during pre-processing.
- Day of the week for which public transport is to be analysed.
- Starting time limits defining the public transport component of the journey, from which the fastest single journey to every destination will be calculated.
- Initial and final modes of transport, as either pedestrian or bicycle.
- A selection of starting points from which to calculate either multi-modal travel times, or durations of those times to equivalent automobile times.
Travel times are always calculated to every destination point in a given network, with a single query returning matrices of times, one row for each origin point, and columns holding travel times to all possible destination points.
