Electronic Road Pricing

File:ERP IU unit.JPG

The scheme consists of ERP gantries located at expressways where traffic was being built up during peak hours. The gantry system is actually a system of sensors on two gantries, one in front of the other. Cameras are also attached to the gantries to capture the rear license plate numbers of vehicles. No new gantries have been implemented since January 2016.

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 stored-value card, the NETS CashCard, is inserted for payment of the road usage charges. 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.

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.{{cite web |url=https://onemotoring.lta.gov.sg/content/onemotoring/home/driving/ERP/erp-2-0.html |title=ERP 2.0 – LTA |access-date=14 February 2024}} 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.

It is anticipated that there will no longer be any need for physical ERP gantries when the system is fully implemented and activated. 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.{{Cite news |last=Lee |first=Nian Tjoe |date=23 October 2023 |title=Next-gen ERP on-board units to be installed from Nov; motorists can opt out of touchscreen display |url=https://www.straitstimes.com/singapore/transport/next-gen-erp-on-board-units-to-be-installed-from-nov-motorists-can-opt-out-of-touchscreen-display |url-status=live |archive-url=https://web.archive.org/web/20231030042123/https://www.straitstimes.com/singapore/transport/next-gen-erp-on-board-units-to-be-installed-from-nov-motorists-can-opt-out-of-touchscreen-display |archive-date=30 October 2023 |access-date=9 November 2023 |work=The Straits Times |language=en |issn=0585-3923}}

Current IU systems will be replaced by onboard units (OBUs) with one-piece units for motorcycles and three-piece units for other vehicles, due to the fact that the current IU system is not operable with the SimplyGo card system that was being introduced in 2017.{{cite web |title=Installation of On-Board Units for Next-Generation ERP System to Commence in Second Half of 2021 |url=https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/9/news-releases/installation-of-on-board-units-for-next-generation-erp-system-to.html |website=LTA |access-date=1 July 2021 |date=8 September 2020 |archive-date=30 June 2021 |archive-url=https://web.archive.org/web/20210630143443/https://www.lta.gov.sg/content/ltagov/en/newsroom/2020/9/news-releases/installation-of-on-board-units-for-next-generation-erp-system-to.html |url-status=live}}{{cite web |last1=Tan |first1=Christopher |title=New ERP system to start in 2023 but no distance-based charging yet; replacement of IU from second half of 2021 |url=https://www.straitstimes.com/singapore/transport/new-erp-system-to-start-2023-but-no-distance-based-charging-just-yet |website=The Straits Times |access-date=1 July 2021 |date=8 September 2020 |archive-date=9 July 2021 |archive-url=https://web.archive.org/web/20210709184550/https://www.straitstimes.com/singapore/transport/new-erp-system-to-start-2023-but-no-distance-based-charging-just-yet |url-status=live}}{{cite web |title=New ERP units to be installed from second half of 2021; no change yet to congestion pricing framework |url=https://www.channelnewsasia.com/news/singapore/new-erp-units-vehicles-installation-satellite-system-13091832 |website=CNA |access-date=1 July 2021 |date=8 September 2020 |archive-date=9 July 2021 |archive-url=https://web.archive.org/web/20210709182541/https://www.channelnewsasia.com/news/singapore/new-erp-units-vehicles-installation-satellite-system-13091832 |url-status=live}}

Co-developed by NCS Group and MHI Engine System, the Onboard Unit (OBU) will be rolled out in phases and the installation is slated to be completed by 2025.{{cite web |url=https://www.straitstimes.com/singapore/transport/what-you-need-to-know-about-the-next-generation-erp-system-and-new-on-board-unit |title=What you need to know about the next-generation ERP system and new on-board unit |work=The Straits Times |date=26 October 2023 |access-date=14 February 2024}} The OBU consists of three components for all vehicles, except for motorcycles, which will remain a one-piece unit.

The three-piece units consists of an antenna, processing unit and a touchscreen display. The antenna and touchscreen display will be affixed on the lower right corner of the front windscreen within sight of the driver, while the processing unit is located on the right side of the passenger side footwell for the three-piece unit.

The OBU is expected to have various features, including being able to display real-time traffic information, and facilitate couponless parking and automatic payment.{{cite web |last1=Tan |first1=Christopher |date=25 February 2016 |title=LTA to roll out next-generation ERP from 2020, NCS-MHI to build system for $556m |url=https://www.straitstimes.com/singapore/transport/ncs-mhi-to-build-islandwide-satellite-based-erp-for-556m |url-status=live |archive-url=https://web.archive.org/web/20190711105144/https://www.straitstimes.com/singapore/transport/ncs-mhi-to-build-islandwide-satellite-based-erp-for-556m |archive-date=11 July 2019 |access-date=1 July 2021 |website=The Straits Times}}

Vehicle owners can choose to not install the touchscreen display, but will be unable to adjust the volume of the OBU. Other features such as a future payment system that will be introduced to the OBU, live traffic data and updates, can be accessed via smartphone applications developed with software development kits released by LTA.

Road users are able to use Contactless e-Purse Application Specification (CEPAS) cards, which can inserted into the processing unit.{{cite web |url=https://www.todayonline.com/singapore/new-erp-system-need-know-board-system-2288566 |title=What you need to know about the ERP 2.0 on-board unit |publisher=TODAY |date=23 October 2023 |access-date=14 February 2024}}

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.{{cite web |url=https://www.todayonline.com/singapore/explainer-why-distance-based-road-pricing-unlikely-anytime-soon-2289551 |title=Explainer: Why distance-based road pricing is unlikely anytime soon |publisher=TODAY |date=25 October 2023 |access-date=14 February 2024}} 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. The physical gantries will be removed in a 3-phase plan after the installation of OBUs is completed in all vehicles.

File:Electronic Road Pricing gantry in Singapore.jpg

The charge for passing through a gantry depends on the location and time. 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$1,000, or one month in jail, if not settled within 30 days.

A lightweight version of the ERP technology has been implemented for use on parking, and is known as the Electronic Parking System (EPS). It has been adopted by several carpark operators and has replaced the use of autopay tickets or parking coupons. These parking systems have also typically switched to charging by the minute.{{Citation needed|date=November 2023}}

In an effort to improve the pricing mechanism and to introduce real-time variable pricing,{{cite news |url=https://www.nytimes.com/2008/03/16/automobiles/16CONGEST.html?ex=1363320000&en=66db1c235736c7ea&ei=5088&partner=rssnyt&emc=rss |author=Ken Belson |title=Importing a Decongestant for Midtown Streets |work=The New York Times |date=16 March 2008 |access-date=6 April 2008 |archive-date=12 May 2008 |archive-url=https://web.archive.org/web/20080512092317/http://www.nytimes.com/2008/03/16/automobiles/16CONGEST.html?ex=1363320000&en=66db1c235736c7ea&ei=5088&partner=rssnyt&emc=rss |url-status=live}} 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.{{cite web |url=http://www.planetizen.com/node/26091 |publisher=PLANETIZEN |title=Predicting Where The Traffic Will Flow |access-date=6 April 2008 |archive-date=4 May 2008 |archive-url=https://web.archive.org/web/20080504003957/http://www.planetizen.com/node/26091 |url-status=live}}

During 2020, ERP was mostly suspended due to circuit breaker measures in response to the COVID-19 pandemic in Singapore.{{Cite news |last=Tan |first=Christopher |date=31 March 2020 |title=ERP at most locations to be suspended from April 6 in light of less commuting amid Covid-19 outbreak |language=en |work=The Straits Times |url=https://www.straitstimes.com/singapore/transport/erp-at-most-locations-to-be-suspended-from-april-6-in-light-of-less-commuting |access-date=9 November 2023 |issn=0585-3923 |archive-date=30 November 2022 |archive-url=https://web.archive.org/web/20221130015411/http://www.straitstimes.com/singapore/transport/erp-at-most-locations-to-be-suspended-from-april-6-in-light-of-less-commuting |url-status=live}}

In 2021, the LTA stated that the existing ERP system, which was about 22 years old at that time, was "reaching the end of its operational life".

During COVID-19, rate reviews were more frequent in February, April, May, August, September and November. After COVID-19, rate reviews were only reduced to February and August.

According to a paper presented in the World Roads Conference 2006, the LTA had been testing a system based on the Global Positioning System that may eventually replace the current Electronic Road Pricing system. The proposed system was said to be able to overcome the inflexibility of having physical gantries, which "are not so flexible when it comes to re-locating them".{{Citation needed|date=June 2024}}

In 2010, then-Transport Minister Raymond Lim announced that a new ERP system was being considered and a tender for the new system would be announced later.{{Cite news |date=30 June 2010 |title=Satellite navigation ERP and electric cars possible on future road system |publisher=Channel NewsAsia |url=http://www.channelnewsasia.com/stories/singaporelocalnews/view/1066660/1/.html |url-status=dead |access-date=2 January 2012 |archive-url=https://web.archive.org/web/20100701192138/http://www.channelnewsasia.com/stories/singaporelocalnews/view/1066660/1/.html |archive-date=1 July 2010}} Subsequently, a tender was called and in 2016, NCS and MHI Engine System were jointly awarded the contract to install the new ERP 2.0 system for S$556 million, which was less than ST Electronics's bid of S$1.2 billion. It was reported that the rollout of the new ERP system would begin in 2020. Then-Chief Executive of LTA stated at the time that the NCS-MHI bid "came within our budget" and was superior to ST Electronics', and he was confident that NCS-MHI would be able to "execute the project in a commercially-viable way" notwithstanding the large difference between the bids.

The ERP 2.0 system was said to replace the existing IU with a more sophisticated OBU the size of a smartphone with various features. The new OBU was intended to be able to provide real-time traffic information and alert drivers of toll roads and the associated charges well in advance.

In September 2020, the initial design of the OBU for vehicles other than motorcycles, such as cars, was criticised as being clunky, inelegant and bulky.{{Cite news |last=Tan |first=Christopher |date=9 September 2020 |title=Motorists laud new ERP features but want more streamlined units |language=en |work=The Straits Times |url=https://www.straitstimes.com/singapore/transport/motorists-laud-new-erp-features-but-want-more-streamlined-units |access-date=9 November 2023 |issn=0585-3923 |archive-date=27 November 2022 |archive-url=https://web.archive.org/web/20221127071844/http://www.straitstimes.com/singapore/transport/motorists-laud-new-erp-features-but-want-more-streamlined-units |url-status=live}}

It was also reported that as a result of the COVID-19 pandemic in Singapore in 2020, the fitting of the new OBUs would be delayed to the second half of 2021, with the new ERP system expected to become operational in mid 2023.{{Cite web |last=Choo |first=Daryl |date=8 September 2020 |title=ERP readers to be replaced with free satellite-based units from 2021: LTA |url=https://www.todayonline.com/singapore/erp-readers-be-replaced-free-satellite-based-units-2021-lta |access-date=19 June 2024 |website=TODAY |language=en}}

In November 2021, the deployment was delayed again to the second half of 2023 due to a global shortage of microchips for the OBUs.{{Cite web |last=Yu |first=Eileen |date=17 November 2021 |title=Singapore delays satellite road toll system due to global chip shortage |url=https://www.zdnet.com/article/singapore-delays-satellite-road-toll-system-due-to-global-chip-shortage/ |access-date=9 November 2023 |publisher=ZDNet |language=en |archive-date=28 May 2023 |archive-url=https://web.archive.org/web/20230528144743/https://www.zdnet.com/article/singapore-delays-satellite-road-toll-system-due-to-global-chip-shortage/ |url-status=live}} Then-Deputy Prime Minister Heng Swee Keat also stated that the technology required for distance-based charging "is still several years away".

Some commentators described the OBU design as "old-fashioned", stating that "the tech is too old" and observed that the new OBU would require more space and more wiring than the existing IU.

In October 2023, LTA announced that the new system would begin to replace the existing ERP system from November 2023 onwards.{{Cite news |last=Lee |first=Nian Tjo |date=23 October 2023 |title=What you need to know about the next-generation ERP system and new on-board unit |language=en |work=The Straits Times |url=https://www.straitstimes.com/singapore/transport/what-you-need-to-know-about-the-next-generation-erp-system-and-new-on-board-unit |access-date=9 November 2023 |issn=0585-3923 |archive-date=2 November 2023 |archive-url=https://web.archive.org/web/20231102052311/https://www.straitstimes.com/singapore/transport/what-you-need-to-know-about-the-next-generation-erp-system-and-new-on-board-unit |url-status=live}} All vehicles are expected to be fitted with the new on-board units by the end of 2025 but the system will not be turned on until further notice.

In March 2024, it was reported that various motorists using the ERP 2.0 system had complained about the location of the card reader component of the OBU. In cars, the card reader was generally installed in the passenger footwell, which made it difficult for drivers to insert or remove their CEPAS card from the driver's seat.{{Cite web |last=Yeoh |first=Grace |date=28 March 2024 |title=Haven't installed your ERP 2.0 unit yet?

The LTA also stated that it would allow drivers to decide where to install the card reader component, subject to space constraints in the relevant vehicle and technical feasibility. {{Cite web |last=Ng |first=Abigail |date=12 April 2024 |title='Too inconvenient': Motorists complain about ERP 2.0 card reader but welcome changes in installation process |url=https://www.channelnewsasia.com/singapore/erp-cars-drivers-card-reader-obu-motorcycles-installation-4250531 |access-date=19 June 2024 |website=CNA |language=en}}

As of April 2024, more than 13,000 vehicles had been fitted with the new OBUs, of which about 75% were company vehicles, such as buses and motorcycles.

In May 2024, the LTA refuted allegations that the new OBUs did not comply with international standards. According to the LTA, the OBU had been tested against the International Electrotechnical Commission's IEC-60068 and IEC-60529 and therefore "meets the relevant global benchmarks for electronic devices" and "when properly installed, it is safe and reliable to use in our operating environment".{{Cite web |last=Ng |first=Hong Siang |date=14 May 2024 |title=LTA refutes online claims of ERP 2.0 on-board unit not complying with international standards |url=https://www.channelnewsasia.com/singapore/lta-erp-board-unit-international-standards-4334141 |access-date=19 June 2024 |website=CNA |language=en}}

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.{{citation |title=Road Congestion Pricing in Singapore: 1975–2003 |author=Sock-Yong PHANG |date=March 2004 |journal=Transportation Journal |volume=43 |issue=2 |pages=16–25 |issn=0041-1612 |url=https://ink.library.smu.edu.sg/soe_research/117 |access-date=5 August 2019 |archive-date=5 July 2019 |archive-url=https://web.archive.org/web/20190705144201/https://ink.library.smu.edu.sg/soe_research/117/ |url-status=live}}

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.{{cite web |title=How ERP works as a speed booster |url=https://www.mot.gov.sg/what-we-do/motoring-road-network-and-infrastructure/Electronic-Road-Pricing/Details/how-erp-works-as-a-speed-booster |website=mot.gov.sg |access-date=16 September 2022 |language=en |date=21 March 2022 |archive-date=20 September 2022 |archive-url=https://web.archive.org/web/20220920163259/https://www.mot.gov.sg/what-we-do/motoring-road-network-and-infrastructure/Electronic-Road-Pricing/Details/how-erp-works-as-a-speed-booster |url-status=live}}

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.{{cite web |last1=A P Menon |first1=Gopinath |title=Getting Singaporeans to embrace a car-lite society |url=https://www.todayonline.com/singapore/getting-singaporeans-embrace-car-lite-society |website=TODAY |access-date=16 September 2022 |language=en |date=18 November 2017 |archive-date=20 September 2022 |archive-url=https://web.archive.org/web/20220920170854/https://www.todayonline.com/singapore/getting-singaporeans-embrace-car-lite-society |url-status=live}}{{cite web |title=Go Car-Lite |url=https://www.ura.gov.sg/Corporate/Get-Involved/Go-Car-Lite |website=ura.gov.sg |access-date=16 September 2022 |archive-date=20 September 2022 |archive-url=https://web.archive.org/web/20220920170517/https://www.ura.gov.sg/Corporate/Get-Involved/Go-Car-Lite |url-status=live}} 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.

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.{{cite web |url=https://www.407etr.com/ |title=407 Express Toll Route |access-date=25 February 2023 |archive-date=25 February 2023 |archive-url=https://web.archive.org/web/20230225070228/https://www.407etr.com/ |url-status=live}}

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.{{cite web |url=https://www.theguardian.com/theissues/article/0,,519534,00.html |title=Q&A: The congestion charge |author=Simon Jeffery |author2=Sarah Phillips |name-list-style=amp |work=The Guardian |date=7 August 2006 |access-date=26 May 2007}}

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.{{cite web |title=Congestion tax in Stockholm from 1 August |website=Swedish Road Administration |url=http://www.vv.se/templates/page3____17154.aspx |access-date=2 August 2007 |url-status=dead |archive-url=https://web.archive.org/web/20070302045327/http://www.vv.se/templates/page3____17154.aspx |archive-date=2 March 2007}} The congestion tax was implemented on a permanent basis on 1 August 2007,{{cite web |title=Trängselskatt i Stockholm |website=Swedish Road Administration |url=http://www.vv.se/templates/page3____10911.aspx |access-date=1 August 2007 |url-status=dead |archive-url=https://web.archive.org/web/20070709043015/http://www.vv.se/templates/page3____10911.aspx |archive-date=9 July 2007}}{{cite web |title=Odramatisk start för biltullarna |website=Dagens Nyheter |url=http://www.dn.se/DNet/jsp/polopoly.jsp?d=1298&a=676098 |date=1 August 2007 |access-date=1 August 2007 |url-status=dead |archive-url=https://web.archive.org/web/20070819051556/http://www.dn.se/DNet/jsp/polopoly.jsp?d=1298 |archive-date=19 August 2007}} after a seven-month trial period was held between 3 January 2006 and 31 July 2006.{{cite web |title=Stockholmsförsöket |website=Stockholmsförsöket |url=http://www.stockholmsforsoket.se/ |access-date=18 July 2007 |url-status=dead |archive-url=https://web.archive.org/web/20070715053128/http://www.stockholmsforsoket.se/ |archive-date=15 July 2007}}

In 2007, Dubai, in the United Arab Emirates, implemented a corridor congestion pricing scheme called 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.{{cite news |url=https://www.nytimes.com/2008/01/27/automobiles/27GREEN.html |title=Toll Discounts for Going Green |newspaper=The New York Times |first=Ken |last=Belson |date=27 January 2008 |access-date=25 February 2023 |url-access=subscription |archive-date=6 January 2018 |archive-url=https://web.archive.org/web/20180106044450/http://www.nytimes.com/2008/01/27/automobiles/27GREEN.html |url-status=live}}{{cite news |url=http://news.bbc.co.uk/2/hi/europe/7167992.stm |title=Milan introduces traffic charge |website=BBC News |date=2 January 2008 |access-date=25 February 2012 |archive-date=28 April 2019 |archive-url=https://web.archive.org/web/20190428051356/http://news.bbc.co.uk/2/hi/europe/7167992.stm |url-status=live}}{{cite news |url=http://www.nysun.com/article/68854 |title=Milan Introduces Congestion Charge To Cut Pollution |website=The Sun |location=New York |date=3 January 2008 |access-date=12 June 2012 |archive-url=https://web.archive.org/web/20200831015107/https://www.nysun.com/foreign/milan-introduces-congestion-charge-to-cut/68854/ |archive-date=31 August 2020 |url-status=dead |url-access=subscription}} 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.{{cite news |url=http://www.thejakartapost.com/news/2018/03/25/jakarta-aims-to-introduce-electronic-road-pricing-in-2019.html |title=Jakarta aims to introduce electronic road pricing in 2019 |newspaper=The Jakarta Post |access-date=25 March 2018 |archive-date=25 March 2018 |archive-url=https://web.archive.org/web/20180325143631/http://www.thejakartapost.com/news/2018/03/25/jakarta-aims-to-introduce-electronic-road-pricing-in-2019.html |url-status=live}}{{Cite news |url=http://www.thejakartapost.com/news/2016/12/15/jakarta-police-request-evaluation-of-odd-even-policy.html |title=Jakarta Police request evaluation of odd-even policy |work=The Jakarta Post |access-date=13 November 2018 |archive-date=2 September 2018 |archive-url=https://web.archive.org/web/20180902012304/http://www.thejakartapost.com/news/2016/12/15/jakarta-police-request-evaluation-of-odd-even-policy.html |url-status=live}}{{cite news |url=http://www.thejakartapost.com/news/2018/02/08/erp-will-be-implemented-in-jakarta-next-year-sandiaga.html |title=ERP will be implemented in Jakarta next year: Sandiaga |newspaper=The Jakarta Post |access-date=13 November 2018 |archive-date=13 March 2018 |archive-url=https://web.archive.org/web/20180313195611/http://www.thejakartapost.com/news/2018/02/08/erp-will-be-implemented-in-jakarta-next-year-sandiaga.html |url-status=live}}
