A calculation tool to support the operational and financial planning phase of DRT services, providing comparisons between PT and four different DRT service models, and across three conceptual scenarios (“accessibility”, “intermodality”, “inclusiveness”).

The calculation tool is based on the following DRT service models:

• Public Transit. Traditional public transit service, with fixed route and stops, and fixed timetables defining the frequency.
• DRT1 – Fixed route, booked stops. Demand responsive service designed around a fixed route, where stops (all, or part of them) are activated only upon request of the passengers.
• DRT2 – Fixed route with deviations. Demand responsive service designed around a fixed route, where some of the stops representing a deviation on the main route are activated only upon request of the passengers.
• DRT3 – Free route, predefined stops. Demand responsive service with no fixed route. The trip is designed according to the booking of origin and destination stops by the passengers, from a predefined list.
• DRT4 – Free route, free stops. Demand responsive service with no fixed route nor fixed stops. The trip is designed according to the booking of origin and destination by the passengers, within the service area.
