ELECTRONIC TOLL COLLECTION SYSTEM
Introduction
One of the biggest complaints of motorists using toll roads is the congestion and delay caused by stopping to pay at the tollbooths.
Many toll authorities have searched for ways to improve the toll collection process. Over the last decade, a significant improvement in this process was implemented and dubbed Electronic Toll Collection (ETC)
Electronic Toll Collection
Electronic toll collection (ETC), is an identification technology, aims to eliminate the delay on toll roads by collecting tolls electronically
COMPONENTS OF ETC SYSTEM
I. AUTOMATIC VEHICLE IDENTIFICATION
II. AUTOMATIC VEHICLE CLASSIFICATION
III. VIDEO ENFORCEMENT SYSTEMS
AUTOMATIC VEHICLE CLASSIFICATION
AVC refers to the processes of the toll-collection system with which the toll equipment is able to determine the configuration of the vehicle.
AVC may need to determine vehicle height, numvideo enforcement system refers to the processes of the toll collection system with which the toll equipment is able to capture
VIDEO ENFORCEMENT SYSTEMS
video enforcement system refers to the processes of the toll collection system with which the toll equipment is able to capture
information on vehicles that have not paid the proper toll.
AUTOMATIC VEHICLE IDENTIFICATION
AVI refers to the identification of vehicles and their owners for the purposes of charging the toll to the customer and providing mechanism for data collection for various traffic management strategies.
RFID TAGS
COMMUNICATES WITH READERS
IDENTIFIES ACCOUNT
DEDUCTS CHARGES
ABOUT AVI
As the vehicle approaches a tag reader site, the roadside antenna emits a signal that is reflected back by the tag located on the windshield.
The identification number is read and is sent to a roadside reader unit where it receives a time, date and location. A central computer uses the code to identify the account and the cost is deducted from the customer’s account.
The type of automatic vehicle identification tag signal that is most commonly used for electronic toll collection is radio frequency. While other types of signals such as laser and infrared (IR) have been tested and deployed, Radio Frequency tags currently provide the most accurate results. Automatic vehicle identification tags can be further broken down into distinct tag types based on the degree to which they can be programmed and the type of power source.
The technological differences between tag types do not affect their abilities to collect travel time data; the necessary data (i.e. unique ID numbers) are transmitted from the transponders to the roadside units regardless of transponder type. Toll facilities or individual users determine the type of tag used
RFID
Radio Frequency Identification is identifying an item based on radio frequency transmission. This technology can be used to identify, track and detect a wide variety of objects. Communication takes place between a reader and a transponder usually called “tag”.
Automatic vehicle identificatin tags are electronically encoded with unique identification numbers.
Roadside readers or antennas are located along the road, in overhead structures or apart of the toll collection booth.
Advantages of Electronic Toll Collection
Makes traveling more convenient, reduces travel times
Saves fuel
Reduces auto emissions
Reduces wait time at toll booths
Save money through individual and business discounts
Increase highway capacity
Processes 250 – 300% more vehicles per lane, reducing delays and traffic congestion
DISADVANTAGES
Job loss
Theft
Stolen tags
Account tampering
Financial loss
Incorrect reads
Fines for motorists
Monetary loss for company
conclusion
The ETC technology concept of prepaying tolls is catching on nationally and globally. It is instituted in Florida. The ETC system is also emerging around the world such as Japan.
