Genoa
Within Genoa the PRISCILLA project will involve a partnership between the
public transport operator (AMT) and the operator of the urban traffic
control system, ELSAG. The trial stage of the PRISCILLA project will be
carried out on 80 junctions and 200-300 buses depending on the chosen
routes. These trials will concentrate on the expansion to a wide area bus
priority network. Within Genoa the operation of such a network will involve
two levels of interaction between the UTC system and the bus management
system. Between the control centres of each system decisions will be made
at a strategic level involving route data exchange and also at a local
level exchanging data necessary to activate bus priority on street. The
PRISCILLA trials will look to develop best practice methods taking into
account the differences between the two control levels, differing levels of
priority, conflicting bus routes and congested networks.

Southampton
At Southampton the PRISCILLA project will involve a partnership between the
City Council (ROMANSE) and Southampton University (TRG). The foundation of
Southampton's trials within the PRISCILLA project will be based upon the
TRG's simulation model known as SPLIT (Selective Priority to Late Buses
Implemented at Traffic Signals). This model allows simulation of bus
movements through networks of traffic signals at which selective bus
priority is provided. Simulation modeling will provide results compatible
with field trials but will also enable a much wider range of scenarios and
priority control strategies to be evaluated. In PRISCILLA it is proposed to
model two sectors of Southampton, a radial route and a central city area.
It is anticipated that different control strategies will be required to
reflect these differing situations. Various alternative strategies for
signal priority will be modeled including options for stage skipping,
adherence to timetable and reductions in bus 'lateness'. Evaluation and
variation of these options will enable optimum priority strategies to be
identified and guidelines produced for implementation.

Toulouse
Within Toulouse the PRISCILLA project will involve a partnership between
the City Council, the public transport authority (SMTC) and the public
transport operator (SEMVAT). As part of the PRISCILLA project the first
objective would be to deploy the centralized bus priority system (developed
within CENTAUR) into the city centre. The CENTAUR project is based on a
centralised system architecture with bus priority achieved through the UTC
system based on requests from the bus fleet management system. The system
would be based on 10 city center bus lanes and 150 traffic intersections
and will use 170 radio-equipped buses. The trial phase would look to
optimize the use of the interconnection between the fleet management system
and UTC in order to improve the bus priority strategy definition process.
