KTA Toll Plazas - Roadway Payment Functionality
Subsystem Description
The Roadway Payment Subsystem (RPS) represents the roadway components of a toll collection, vehicle miles traveled (VMT), congestion charging, and other systems that support payment from a vehicle. As a toll collection system, this subsystem provides the capability for vehicle operators to pay tolls without stopping their vehicles. It supports use of locally determined pricing structures and includes the capability to implement various variable road pricing policies. Each transaction is accompanied by feedback to the customer indicating the general status of the customer account. A record of the transactions is provided to the Payment Administration Subsystem for reconciliation and so that the customer can periodically receive a detailed record of the transactions.
The RPS can represent equipment at fixed locations or mobile equipment that supports spot inspection to verify the vehicle equipment is configured correctly and operational. Fixed roadway equipment supports relay of VMT data and equipment status to the Payment Administration Subsystem. RPS elements can be located at traditional toll collection locations (i.e. toll plazas) to support traditional roadway toll functions, as well as at gas stations or public or privately operated auto mechanic shops or vehicle inspection stations) for relaying VMT data.
