2. The project results
The project is an integrated system and
services designed for public transport
travellers, operators and administrators.
The integrated system is illustrated in the
below figure.
Figure 1 logical architecture of the
SMARTBUS system
The SMARTBUS system is comprised of:
A. the ticheting system which implements:
• electronic travel cards,
• system for travel card issuance and
reload,
• system for card validation aboard the
vehicle;
• system for card inspection based on
mobile equipments Pocket PC (PDA)
compatibile;
• communication system at small and
remote distance;
• back-office information system.
B. automatic vehicle localization system
(AVL) which implements:
• AVL system aboard the vehicle for
localization using the GPS system and
mobile data communication with the
dispatcher using GSM/GPRS;
• central system for mobile
communication with the vehicles;
• software dispatcher for monitoring and
analysis of the transport vehicle
circulation.
C. passenger information system:
• aboard the vehicle, regarding the current
route, the next bus station, the links to
other bus routes, other general interest
informations. The system comprises:
o the information system provided by
the bus manufacturer,
o "SMARTBUS" information system,
which localizes the bus on a route
map, controlled by the board
computer.
• in the bus stations, regarding the
estimated arrival minutes of the nearest
bus, information about the routes
(modifications, traffic and weather
information). The system consists of:
o alphanumeric displays (signs);
o embedded system for sign control
and data communication;
o software dispatcher for the
management of the mobile
communications with the bus
stations;
o software application for prediction
of the vehicle arrival minutes in
each bus station.
D. board computer/master driver console,
implemented with a portable computer,
which performs data storage, integration and
management of the "SMARTBUS"
functionalities aboard the vehicle (driver
authentication, route configuration, travel
card validation, GPS data reception and
transmission using GSM/GPRS channels,
driver and passenger information).
E. public information and support
applications, accessed from various
software/hardware platforms: info-kiosk,
SMARTBUS ONLINE website.
F. back-office information system for
"SMARTBUS" services for data
monitoring, dispatching, management,
analysis, reporting, decision support, which
consist in computer network, data bases,
data warehouses, multidimensional cubes,
OLTP (transactional) and OLAP
(operational) applications and services. It is
sustained by two categories of services and
applications:
a) operational management applications:
a1) support for financial clearing
operations for the ticketing system; a2)
graphic dispatcher for the AVL system;
a3) activity reports;
