ERP Singapore

ERP Singapore stands for the Electronic Road Pricing , in Singapore . It is a traffic management system that was  implemented in 1998 to address the road congestion faced by many road users in Singapore . It complements the COE (Certificate Of Entitlement)  which was implemented earlier in 1990 .

ERP Singapore | Electronic Toll System

The ERP Singapore  is actually an electronic toll collection system to manage traffic by road pricing . Singapore is the first city in the world to implement electronic road tolling system to address road congestion . The ERP Singapore system require gantries to be installed at major roads that face congestion problems , such as roads leading to the Central Business District , especially along the expressways and arterial roads with heavy traffic to discourage users during these peak periods .   These gantries comprise of systems of sensors and cameras to make electronic deduction and photographing vehicles license  plates  .

ERP  Singapore | How does it work

This is what is needed for ERP Singapore system to work .

1.All cars in Singapore will have a special gadget incorporated into the car , called the IU (In Vehicle unit) . This gadget is normally mounted on the right had side of the dashboard below the windscreen , directly in front of the driver . In the IU , there is a cashcard or a stored-value card . Each IU has a unique identity  to each vehicle . This is photograph of a IU (In Vehicle unit) with a cash card displaying the amount (SGD$65.21) available .

2. Electronic gantry .The gantry detects the vehicle and its associated unique IU . When a card with this IU goes through a gantry , the gantry detects the car and its associated IU  and make the necessary road usage deduction from the cashcard in the IU automatically .  The sensors installed on the gantry communicates with the IU via short-range communication system and the amount deducted is displayed to the driver on the small LCD screen od the IU .  As the gantry is managed and electronically controlled , it can adjust the toll fees according to the time of the day and different days and thus effectively adjusting and moderating traffic . The “toll fees”  will be most expensive during peak hours , so as to discourage road users during this peak period so that road users can look for alternative routes .

With the advancement in Global Positioning System  (GPS)  technology , in 2006 , the Land Authority of Singapore intent to eventually replace the current gantry ERP with a system base on GPS .  The new system will provide flexibility and speed due to the physical constraints of the gantry especially when it comes to putting up new gantries or even relocating existing ones .

The current ERP technology has  also been incorporated , adopted and used by car park operators in Singapore . It is a more effective and efficient systems as it do away with the auto pay tickets or parking coupons that has been used over many years in Singapore . The new  system can charge parking by minutes  and reduces overhead , especially on labour cost

 ERP Singapore | Similar ideas in major cities

Several major cities of the world has looked into the ERP Singapore system . Some the examples are as follows ;

  •  in Toronto , Ontario , Canada  , an electronic road pricing system is being used on highway 407 to collect tolls electronically  .
  •  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.
  •  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.
  •  In 2007, Dubai, at the United Arab Emirates, implemented a corridor congestion pricing scheme called Salik which works on similar principles.
  •  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.

ERP  Singapore| Conclusions

The ERP Singapore  system , although unpopular among motorists , it has served its purpose  . With a proper pricing models it has helped to change road usage patterns . Traffic has decreased by 25000 during peak hours with average road speed improves by 20% . Within the restricted zone itself , traffic is down by 13% during ERP operational hours . During peak vehicular traffic period , traffic has eased and spread to “off-peak” hours , which means better 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.
