Dores (transport reservation system) for passenger bus services is an innovative tool for on-line booking and sales of seat reservation tickets for individual connections of the passenger bus transport system, permitting not only the convenient and reliable checking of passengers by the driver directly on the bus, but that can be also be utilised by retail partners and commercial units of individual carriers.
Back Office, with all the necessary functionalities such as the selection of routes, connections, and journeys, bus types, means of payment, planning of journeys, timetables, pricing, booking and selling of seat reservation tickets, cash-office for the receipt of payments, statistics and reports. Access to the system is based on the defined user rights of the operators (authorised personnel of the carrier) and the sellers (internal, by the carrier or external by the sales partner).
The Driver's Terminal, which is located directly in the bus and permits the driver to sell tickets to passengers or to check passengers with pre-purchased seat reservation tickets. The driver's terminal includes an LCD panel, a power supply, a GPRS modem for data transfer with the Back Office, a printer, specialised software application and an optional smart card reader, if the carrier uses a system of prepaid charging and withdrawal of credit.

Seemingly very advantageous for
the carrier appears to be the connection between Dores and an
Internet sales portal which, in the event of payment by credit card
or by RFID smart card (electronic wallet with credit) facilitates
the convenient sale of "electronic seats" without the
intervention of a human operator and also for the simple
establishment of bonus programmes for loyal customers. Both of
these lead to a still greater level of efficient utilisation of the
capacity of buses on individual routes. Passengers can also book
their seats while on the bus using specially coded SMS
messages.
