Electronic Road Pricing

Source: Wikipedia, the free encyclopedia.

The Electronic Road Pricing (ERP) system is an electronic toll collection scheme adopted in Singapore to manage traffic by way of road pricing, and as a usage-based taxation mechanism to complement the purchase-based Certificate of Entitlement system. There are a total of 93 ERP gantries located throughout the country, along expressways and roads leading towards the Central Area.[1] As of February 2023, there were a total of 19 ERP gantries in operation, as compared to 77 in 2020 before the COVID-19 pandemic in Singapore.[2]

The ERP was implemented by the

Singapore Area Licensing Scheme (ALS) that was first introduced on 11 August 1974 after successfully stress-testing the system with vehicles running at high speed. The system uses open road tolling; vehicles do not stop or slow down to pay tolls.[4][5]

Singapore was the first city in the world to implement an electronic road toll collection system for purposes of congestion pricing.[6] Its use has inspired other cities around the world in adopting a similar system, particularly London's Congestion Charge Zone (CCZ) and Stockholm's congestion tax.[7] It has also been proposed in New York City and San Francisco.

The system

The scheme consists of ERP

gantries located at all roads linking into Singapore's Central Area. They are also located along the expressways and arterial roads with heavy traffic to discourage usage during peak hours. The gantry system is actually a system of sensors on 2 gantries, one in front of the other. Cameras are also attached to the gantries to capture the rear license plate numbers of vehicles. As of August 23, 2023, there were 93 ERP gantries in Singapore.[1]
New gantries are implemented where congestion is severe, like expressways and other roads.

A device known as an In-vehicle Unit (IU) is affixed on the lower right corner of the front windscreen within sight of the driver, in which a

NETS CashCard, is inserted for payment of the road usage charges.[5] The second generation IU accepts Contactless NETS FlashPay and EZ-Link
. The cost of an IU is S$150. It is mandatory for all Singapore-registered vehicles to be fitted with an IU if they wish to use the priced roads.

Mitsubishi Heavy Industries Ltd sold the IU technology to Singapore, and the project was spearheaded by a consortium comprising Philips Singapore Pte Ltd., Mitsubishi Heavy Industries Ltd., Miyoshi Electronic Corporation and CEI Systems and Engineering (now known as CSE Global Ltd.) in 1995 through an open tender.

When a vehicle equipped with an IU passes under an ERP gantry, a road usage charge is deducted from the CashCard in the IU. Sensors installed on the gantries communicate with the IU via a dedicated short-range communication system, and the deducted amount is displayed to the driver on an LCD screen of the IU.

ERP 2.0 system

The ERP 2.0 system is a Global Navigation Satellite System (GNSS) based system, as opposed to the current system with physical gantries located along expressways, as well as roads and arterial roads leading to the CBD.[8] With the new system, the ERP scheme will move towards a distance based charging policy, instead of the current system, where a fixed toll is charged when vehicles pass through a physical ERP gantry.[9] The system also shows real-time traffic information, couponless parking and automatic payment.[9] There will be no need for big gantries when the system starts, with current IU systems replaced by onboard units (OBUs) with one-piece units for motorcycles and three-piece units for other vehicles.[10][11][12][13]

Joinly developed by

NETS CashCard will no longer be compatible with the OBU system.[15]

LTA announced that the distance-based charging policy will not be implemented in the near future, with no concrete date on when the new policy will take place.[16] The current ERP charges will remain the same, with the OBUs able to work the same as the IUs when passing through a physical ERP gantry.[15] The physical gantries will be removed in phases after the installation of OBUs is completed in all vehicles.[14]

The charge for passing through a gantry depends on the location and time, the peak hour being the most expensive. Examples include a trip from Woodlands to Raffles Place via Yishun – CTE – CBD will cost about S$15 during peak as the driver will pass about 5 gantries, whereas during lunchtime, it will cost about S$2. Foreign visitors driving foreign-registered private vehicles on priced roads, during the ERP operating hours, could choose to either rent an IU or pay a daily flat fee of

S$5 regardless how many ERP gantries entered, the payment is done and information is stored by Autopass Card
until the vehicle leaves Singapore. Foreign-registered commercial vehicles, however, are required to install an IU.

If a vehicle owner does not have sufficient value in their CashCard (or EZ-Link) when passing through an ERP, the owner receives a fine by post within two weeks. The violator must pay the ERP charges plus a $10 administration fee within two weeks of the notice. Online payment is allowed; listing just the Vehicle Registration Number is required. Otherwise, a penalty of S$70 is issued by registered post to the vehicle owner, which rises to S$1000, or one month in jail, if not settled within 30 days.

History

Night works during the installation of a new ERP gantry at Hillview

According to a paper presented in the World Roads Conference 2006, the LTA has been testing a system based on the Global Positioning System that may eventually replace the current Electronic Road Pricing system. The proposed system overcomes the inflexibility of having physical gantries, which "are not so flexible when it comes to re-locating them".

A lightweight version of this same technology is implemented for use on parking, known as the Electronic Parking System (EPS). It has since been adopted in favour by several carpark operators, superseding the use of autopay tickets or parking coupons. These systems have also typically switched to charging by the minute.[citation needed]

In an effort to improve the pricing mechanism and to introduce real-time variable pricing,[17] Singapore's Land Transport Authority, together with IBM, ran a pilot from December 2006 to April 2007, with a traffic estimation and prediction tool (TrEPS), which uses historical traffic data and real-time feeds with flow conditions from several sources, to predict the levels of congestion up to an hour in advance. By accurate estimating prevailing and emerging traffic conditions, this technology is expected to allow variable pricing, together with improved overall traffic management, including the provision of information in advance to alert drivers about conditions ahead, and the prices being charged at that moment.[18]

This new system integrates with the various LTA's

traffic management existing systems, such as the Green Link Determining System (GLIDE), TrafficScan, Expressway Monitoring Advisory System (EMAS), Junction Electronic Eyes (J-Eyes),[19] and the Electronic Road Pricing system. The pilot results were successful, showing overall prediction results above 85 percent of accuracy. Furthermore, when more data was available, during peak hours, average accuracy raised near or above 90 percent from 10 minutes up to 60 minutes predictions in the future.[20]

During 2020, ERP was mostly suspended due to circuit breaker measures in response to the COVID-19 pandemic in Singapore.[21]

ERP 2.0

In 2010, Transport Minister

ST Electronics's bid of S$1.2 billion.[9]
The new ERP system was to start rolling out from 2020.

The initial design of the OBU for other vehicles were criticised as "clunky, inelegant and takes up too much space".[23]

As a result of the COVID-19 pandemic in Singapore in 2020, the fitting of the new OBUs was delayed to the second half of 2021 with the new ERP system operational in mid 2023.[13]

In November 2021, the deployment was delayed again to the second half of 2023 due to a global shortage of microchips for the OBUs.[24]

In October 2023, LTA announced ERP 2.0, a satellite navigation based system, to replace the ERP system.[25] All vehicles are expected to be fitted with the new on-board units by end of 2025 but the system will not be turned on till further notice.[25] For OBU, vehicle owners can opt out of the touchscreen display component and the information needed can be retrieved by other existing mobile applications.[26] After all the vehicles are installed with the new OBU, existing ERP gantries will be removed with new visual markers or signs to indicate ERP charging locations.[27]

Impact

A study on the long-term effects of congestion pricing in Singapore claimed that "traffic congestion had not been eliminated—it had merely been shifted in time and location" and that the average travel time has increased.[28]

In contrast, another report stated that road traffic decreased by nearly 25,000 vehicles during peak hours, with average road speeds increasing by about 20%. Within the restricted zone itself, traffic has gone down by about 13% during ERP operational hours, with vehicle numbers dropping from 270,000 to 235,000. It has been observed that car-pooling and public transport has increased, while the hours of peak vehicular traffic has also gradually eased and spread into off-peak hours, suggesting a more productive use of road space. In addition, it has been noted that average road speeds for expressways and major roads remained the same, despite rising traffic volumes over the years.[29]

In some cases, the implementation of an ERP gantry along a road may move the traffic to outer roads or shift would-be car users towards public transport. One instance of this is that the ERP gantries have been said to have caused traffic to increase substantially in the arterial roads. In response, congestion on the East Coast Parkway was relieved with the opening of Marina Coastal Expressway on 29 December 2013. The rising traffic has prompted the LTA to encourage more Singaporeans to switch to public transport as part of the country's general "car-lite society" plan, by building more MRT train lines and introducing more bus services.[30][31] The full completion of the Downtown MRT line on 21 October 2017 complements the Pan Island Expressway. The Thomson–East Coast MRT line also runs largely parallel to the Seletar Expressway and East Coast Parkway.

Adoption by other metropolitan areas

In Ontario, Canada, an electronic road pricing system is used on Highway 407 to collect tolls electronically and billed to the owner of the car by taking a picture of its license plate.[32]

The ERP system attracted the attention of transport planners and managers in other metropolitan areas, particularly those in Europe and the United States. For example, the London congestion charge was introduced on 17 February 2003, after London officials visited Singapore to study the ERP system, and used it as a reference for the London system. London's charge area was expanded in 2007.[7]

The Stockholm congestion tax is also a congestion pricing system implemented as a tax which is levied on most vehicles entering and exiting central Stockholm, Sweden.[33] The congestion tax was implemented on a permanent basis on 1 August 2007,[34][35] after a seven-month trial period was held between 3 January 2006 and 31 July 2006.[36]

In 2007,

Salik which works on similar principles. In January 2008, Milan introduced a traffic charge scheme as a one-year trial, called Ecopass, and exempts high emission standard vehicles and some alternate fuel vehicles.[37][38][39] This tax was substituted in 2012 by the Area C
system, which places a charge on nearly all vehicles entering the city centre during weekdays.

A similar system is expected to be operational on selected roads in Jakarta, the capital of Indonesia by early 2019.[40][41][42]
