RFID for Toll
The process of collecting tolls manually significantly
slows traffic as it passes through toll plazas.
Traffic must slow then come to a complete stop.
Often a ticket must be exchanged and the toll
determined, then the driver must pay the toll
and the toll plaza operator makes change and
provides a receipt. This process can often take
a minute or more to complete. This results in
increased transit time, frustration for drivers
particularly during busy traffic times, increased
fuel consumption and its associated environmental
impact. There are also substantial costs incurred
by the toll operator in the form of increased
operational costs as toll booths must be staffed
and increased real estate requirements to accommodate
the number of toll gates to service vehicles.
These must be sized to accommodate rush hour
times and during the rest of the day often stand
idle. This real estate requirement substantially
increases capital cost of the toll way particularly
in urban areas and can make plaza location a
major routing constraint.
Optimum traffic flow can be realized by the adoption
of a fully automated post pay toll collection
system. However, such a solution raises significant
concerns in China due to the challenge of post
pay toll collection.
As a result a pre-paid solution is preferred.
A pre-paid solution substantially increases the
technological challenge in the development of a
solution as it forces the need for a real-time
transaction processing system. The proposed solution
consists of a back-end solution located at a geographically
remote Data Centre and a local real-time transaction
processing system located at the toll plaza. This
eliminates the need for a highly reliable high
speed data network between all toll plazas and
allows the application to leverage existing data
