DescriptionThis field-to-vehicle application area covers the interface between a toll collection or parking facility and a vehicle for the purpose of electronic toll or fee collection. The interface supports a number of operational concepts ranging from the infrastructure simply reading the vehicle tag ID to more complex read/write scenarios. The vehicle tags are read and possibly updated electronically via dedicated short-range communication between the field equipment and the vehicle. The population of toll tags and roadside readers that these systems utilize can also be used to collect traffic data for highway authorities. This data can be collected as a natural by-product of the toll collection process or collected by separate readers that are dedicated to probe data collection.
National ITS Architecture InterfaceThis application area includes the dedicated short range communications interface between the Vehicle Subsystem and the Toll Collection and Parking Management Subsystems and is used for electronic toll and parking fee collection. The interface between the Vehicle Subsystem and Toll Collection Subsystem can be as simple as a reader electronically reading the vehicle's tag id and billing the user or debiting the user account off-line, or as complex as interacting with the tag, debiting the tag directly, and storing the new amount on the tag. A similar exchange of information occurs between a Parking Management Subsystem and a Vehicle Subsystem's parking tag, except fees are debited for parking lot charges based upon the time the vehicle entered the lot.
Applicable StandardsIn general, the following standards are applicable to Toll/Fee Collection deployments. To determine which specific standards are applicable for a deployment you will need to determine which architecture flows will be needed for the Toll/Fee Collection piece of your deployment. Contact your local FHWA ITS Division Specialist or an ITS Standards Program Field Support Team contact
