What’s in news?

Parking projects linked to the radio-frequency identification (RFID) system set up at 13 toll booths may soon be undertaken on a pilot basis.


Supreme Court directed in order to curb the entry of vehicles over 10 years old and to reduce congestion at the toll booths.

Key data’s:

  • The Nodal Agency for this project: South Delhi Municipal Corporation (SDMC)
  • The SDMC initiated the parking projects linked to the radio-frequency identification (RFID) system set up at 13 toll booths may soon be undertaken at Lajpat Nagar, Kamla Nagar and Krishna Nagar on a pilot basis.
  • This will be implemented by the Environment Pollution Prevention & Control Authority (EPCA)and it will soon develop a pilot project to tie up the RFID systems with parking.
  • For the first time this decision has recognized a pedestrian’s right to walk and identified that free parking is not a right.
  • It facilitates a cashless transaction of toll tax and environmental congestion charge (ECC) from commercial vehicles through automatic systems.
  • Currently it has been deployed, through the South Delhi Municipal Corporation (SDMC) at 13 border points from where, officials said 80% of the traffic entering Delhi passes. 
  • Features: Identifying the amount of money a particular vehicle owes in parking charges, whether it has been paid or not. 
  • Vehicles parked in these areas are primarily residential, the EPCA would also explore installing similar tags on private vehicles or developing an alternative system.
  • Based on the outcomes from these areas, expanding it to other areas will also be explored.
  • A pre-registration website ( was launched to encourage vehicle owners to recharge easily.
  • After the completion of the pilot projects, EPCA will submit a report in the apex court on the learnings, benefits, shortcomings and how it can be taken forward.


  • The new system allows automatic collection of MCD tax and environment compensation charge from commercial vehicles. 
  • Reducing pollution by easing traffic congestions.
  • Plug revenue leakage by ensuring transparency.

RFID toll collection mechanism:

  • 3,06,812 vehicles had been pre-registered for the RFID tags, however, very few people had recharged their accounts.
  • The mechanism introduced to reduce the toll congestion and environmental pollution. This mechanism also promotes the Cashless payment of toll charges.
  • But many vehicles with the tags were still paying in cash. Such vehicles will now be stopped at the toll plazas.

Radio-frequency Identification (RFID) technology:

  • RFID technology uses electromagnetic fields to automatically identify and track tags which are containing electronically-stored information.
  • A two-way radio transmitter-receivers called interrogators or readers send a signal to the tag and read its response.


  • It is mandatory for cars and trucks sold after December 1, 2017, to be fitted with a FASTag
  • A FASTag is a reloadable tag that automatically deducts toll charges and allows a vehicle to pass through a toll gate without stopping for the payment
  • It uses radio frequency identification (RFID) technology to make cashless payments through a prepaid account linked to it.
  • The tag, which is valid for five years, comes in seven different colours. They are violet, orange, yellow, green, pink, blue, black. Each colour is assigned to a particular category of vehicles
  • The NHAI also has a mobile application for FASTag that allows users to buy and recharge these tags as well as seek information on toll rates on different routes.
