National Parks Toll Collection System
Typical ETC systems can improve the traffic flow
through the toll area. Manual toll collection
lanes handle about 350 vehicles per hour and
automatic coin machine lanes handle about 500
vehicles in the same time period.
An ETC lane can process 1,200 vehicles per hour when the lane is located in a traditional plaza configuration with island structures on each side of the lane and up to 1,800 vehicles per hour in all-electronic tolling (AET) configurations.An AET lane offers over five times the flow rate of a manual lane and nearly four times the flow of an automatic coin machine lane.
systems properly identify each vehicle to charge
the toll to a particular customer. This ETC
method is typically done with various AVI
technologies such as a bar coded label affixed to
the vehicle, proximity card, radio or infrared
transponder, and automatic license plate
A majority of the AVI systems used involve radio frequency identity (RFID) and plate recognition technologies. The RFID system uses an antenna to communicate with a transponder in each registered vehicle, while video tolling identifies the license plate and charges a customer or sends a bill to unregistered drivers with help from the Department of Motor Vehicle’s address database.
