EZ TAG is an electronic toll collection system in Houston, Texas, United States, that allows motorists to pay tolls without stopping at toll booths. Motorists with the tags are allowed to use lanes reserved exclusively for them on all Harris County Toll Road Authority (HCTRA) roads. As of late 2003, the EZ TAG can also be used on all lanes of tolled roadways in Texas that accommodate electronic toll collection.
To participate, a driver signs up through the EZ TAG website, via telephone, or at one of the store locations. Next, the customer receives a small, white radio frequency transponder which must be affixed to the inside of their windshield behind their rear view mirror. Finally, when passing through a toll plaza, the driver chooses lanes specially equipped with sensors that can read EZ TAG transmitters and deduct the appropriate amount from their accounts.
Houston Transtar uses EZ TAG sensors, which are placed at numerous points across Greater Houston, for their Automatic Vehicle Identification (AVI) traffic monitoring system. By tracking the movement of individual transponder tags (EZ TAG user vehicles) over the city, the system can generate real time traffic information for use by the general public. The personal information about the EZ TAG customer is not compromised in this process because the EZ TAG database and the AVI system are not interconnected.
In May 2006, HCTRA introduced a new version of the transponder tag. Instead of battery-powered radio transmitters, the new tags are adhesive stickers with a button-sized microchip in the middle of, and a reflective antenna system throughout the tag. These new tags are sold, rather than rented, so they help save money over the life of the tag by eliminating the monthly $1 rental fee. The battery tag's $15 security deposit can be applied to the purchase of the sticker tag.
Removing the sticker after placement has a high probability of either separating the chip from the antenna, de-tuning the antenna from its designated frequency, or both, therefore invalidating the tag for future use. The tag also relies on the windshield for an amplification effect, and its effective range is greatly reduced if it is not mounted on a glass substrate. This range reduction is so much that not having a tag properly mounted will result in it not reading at all in toll lanes.
These characteristics are much different compared to the old battery tags, which would read fine if not mounted properly. As such, some toll patrons attempt to hold up their sticker tags when driving through the toll lanes, and appear mystified when they do not work as their old tags did.
The new tag uses three different protocols, or communications methods, with the tag readers—ATA, eGo and SeGo.
The protocol used in Houston is ATA for automatic equipment identification; however, a driver in Houston can conceivably use the tag in another state where the other protocols are used. In addition, the tags support ANSI INCITS 256-2001 and ISO 10374. The tag is read by scanners as far as 31.5 feet (9.6 m) at 915 MHz, and the tag features a 2048-bit read/write passive memory. [1]
To duplicate a 915 MHz EZ TAG, a copy of the ROM 2048-bit chip must be dumped and loaded into another ROM chip and a matched inductance of the RFID EZ TAG surface needs to be constructed. [2] Blank 915 MHz RFID pads can be bought online. [3]
As of January 2008, three different sets of EZ Tags have been released. The differences are purely cosmetic.
Despite the similarity in the names, EZ Tags are not compatible with the E-ZPass system in the northeast U.S.
In November 2015, HCTRA announced a new Cash Reloadable EZ Tag. The EZ Tag by BancPass can be reloaded with cash at major retailers, or the user can reload online using a debit or credit card. The EZ Tag by BancPass also differs from the standard EZ Tag by not reloading automatically. The user is notified when the account balance gets low, and the user can choose when and how much to put on the user's account.
The EZ Tag by BancPass is available online, at H-E-B grocery stores and at Corner Store by Valero. Accounts can be reloaded online or at any H-E-B, CVS or Corner Store by Valero.
A toll road, also known as a turnpike or tollway or toll gate, is a public or private road for which a fee is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and maintenance.
Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods.
Electronic toll collection (ETC) is a wireless system to automatically collect the usage fee or toll charged to vehicles using toll roads, HOV lanes, toll bridges, and toll tunnels. It is a faster alternative which is replacing toll booths, where vehicles must stop and the driver manually pays the toll with cash or a card. In most systems, vehicles using the system are equipped with an automated radio transponder device. When the vehicle passes a roadside toll reader device, a radio signal from the reader triggers the transponder, which transmits back an identifying number which registers the vehicle's use of the road, and an electronic payment system charges the user the toll.
E-ZPass is an electronic toll collection system used on toll roads, toll bridges, and toll tunnels in the Eastern United States, Midwestern United States, and Southern United States. The E-ZPass Interagency Group (IAG) consists of member agencies in several states, which use the same technology and allow travelers to use the same transponder on toll roads throughout the network.
FasTrak is the electronic toll collection (ETC) system used in the state of California in the United States. The system is used statewide on all of the toll roads, toll bridges, and high-occupancy toll lanes along the California Freeway and Expressway System.
SunPass is an electronic toll collection system within the state of Florida, United States. It was created in 1999 by the Florida Department of Transportation's (FDOT's) Office of Toll Operations, operating now as a division of Florida's Turnpike Enterprise (FTE). The system utilizes windshield-mounted RFID transponders manufactured by TransCore and lane equipment designed by companies including TransCore, SAIC, and Raytheon.
Touch 'n Go is a contactless smart card system used for electronic payments in Malaysia. The system was introduced in 1997 and is widely used for toll payments on highways, public transportation, parking, and other services. The card is equipped with a radio-frequency identification (RFID) chip that allows users to make payments by simply tapping the card on a reader device. Touch 'n Go cards can be reloaded with funds either online or at designated reload kiosks. The system has become a popular and convenient way for Malaysians to make cashless transactions.
Open road tolling (ORT), also called all-electronic tolling, cashless tolling, or free-flow tolling, is the collection of tolls on toll roads without the use of toll booths. An electronic toll collection system is usually used instead. The major advantage to ORT is that users are able to drive through the toll plaza at highway speeds without having to slow down to pay the toll. In some installations, ORT may also reduce congestion at the plazas by allowing more vehicles per hour/per lane.
State Highway 249, also known depending on its location as West Mount Houston Road, the Tomball Parkway, Tomball Tollway, MCTRA 249 Tollway, or the Aggie Expressway, is a 49.443-mile (79.571 km) generally north–south highway in Southeast Texas. The southern terminus is in North Houston at Interstate 45 (I-45). The current northern terminus of the highway is east of Navasota at SH 105.
The Westpark Tollway, also Fort Bend Westpark Tollway, is a controlled-access toll road in Texas, serving western Houston and Harris County, and northeastern Fort Bend County. Construction on the facility began in 2001 and portions of the road were opened to traffic in May 2004. Construction of the roadway was completed in August 2005. The Westpark Tollway begins on Westpark Drive just past the South Rice Avenue intersection in the Uptown District of Houston and runs approximately 22 miles (35 km) west to Farm to Market Road 1093 just past Farm to Market Road 723 in Fulshear, Texas. It runs roughly parallel and to the south of Westheimer Road in Harris County and concurrently with FM 1093 in Fort Bend County.
TxTag, operated by the Texas Department of Transportation (TxDOT), is one of three interoperable electronic toll collection systems in Texas. The system is also interoperable with the K-TAG system used in Kansas and the Pikepass system used in Oklahoma.
The North Texas Tollway Authority (NTTA) is a not-for-profit government organization that maintains and operates toll roads, bridges, and tunnels in the North Texas area. Functioning as a political subdivision of the State of Texas under Chapter 366 of the Transportation Code, the NTTA is empowered to acquire, construct, maintain, repair and operate turnpike projects; to raise capital for construction projects through the issuance of turnpike revenue bonds; and to collect tolls to operate, maintain and pay debt service on those projects.
The Fort Bend County Toll Road Authority (FBCTRA), also called the Fort Bend Grand Parkway Toll Road Authority (FBGPTRA), operates three toll roads in Fort Bend County and is headquartered at 1 Fluor Daniel Dr in Sugar Land in the U.S. state of Texas.
The Harris County Toll Road Authority maintains and operates a 103-mile (165.8 km) toll road system in the Greater Houston area of Texas, United States. Its headquarters are located in Houston's Fairbanks/Northwest Crossing neighborhood.
Video tolling is a form of electronic toll collection that uses video or still images of a vehicle's license plate to identify a vehicle liable to pay a road toll. The system dispenses with collection of road tolls using road-side cash or payment card methods, and may be used in conjunction with "all electronic" open road tolling, to permit drivers without an RFID device to use the toll road.
Transponder timing is a technique for measuring performance in sport events. A transponder working on a radio-frequency identification (RFID) basis is attached to the athlete and emits a unique code that is detected by radio receivers located at the strategic points in an event.
There are approximately 25 current toll roads in the state of Texas. Toll roads are more common in Texas than in many other U.S. states, since the relatively low revenues from the state's gasoline tax limits highway planners' means to fund the construction and operation of highways.
NationalPass is an interoperable service created by TransCore, which is designed to eventually provide single transponder access to all public toll roads and bridges in North America.
HGS (Hızlı Geçiş Sistemi; English: Fast Pass System is an electronic toll collection system of radio-frequency identification transponder type available on toll roads and toll bridges in Turkey. It is obtainable in a sticker or card form. Payment is handled by antenna on the toll booth, which collect money from the account associated with the tag. Additionally, smart cameras are used to detect the license plate and class of the vehicle. Despite these features, HGS is more cost-efficient compared to the OGS system.
