Congestion Charging Zone

In order to control traffic and prevent air and noise pollution in special areas of a city, municipalities may require drivers to have permission to enter or pass through designated “congestion zones”.

The creation of a congestion charge zone serves to control the passage of motorists in a city’s high-congestion areas, and can become a source of income for the municipality as motorists are charged for legal use of the zones, and additionally enforced by ticketing. The method of charging for passage in these zones can be set either statically or dynamically. A static payment strategy means that the motorist will be charged a constant rate where the price is independent of traffic flow. Oppositely, in a dynamic payment strategy the municipality can calculate price of use based on traffic flow, and charge motorists based on the demand in the congestion zone. Because drivers will be required to pay more as demand on the congestion zone increases, a dynamic pricing strategy can be used as a tool by the traffic manager to ease traffic at peak periods or diffuse it in several hours, resulting in a more even traffic flow. Creating a charge-for-use congestion zone in a city's most congested area is a proven efficient strategy to reduce traffic.


  • Intelligent traffic analysis and Formation of big data
  • Ability to charge motorists, Vehicle whitelist and blacklists for use of the congestion zone
  • Compiled, accessible history of each user
  • Modularity in design and Absolute accuracy after rechecking
  • Plate numbers can be distinguished and Automatic number plate recognition (ANPR)
  • Ability to integrate with a payment channel with several pre-paid or post-paid methods
  • Monitoring, Control of passage through each crossing and control center


  • Smart control of traffic flow
  • Reduction of traffic jams, air and noise pollution
  • Efficient and easy management of transportation

This system consists of two main parts: the central platform and a traffic control center. The central system consists of a platform for traffic management, which monitors real-time activities in the congestion zone with a list of permitted vehicles. The central management platform is regulated at the traffic control center, which monitors real-time activities within the congestion zone, defines policies, receives and manages payments, tickets system violators and maintains vehicle white and black lists. The municipality may choose a static or dynamic payment strategy for entrance to the controlled zone. Multi-lane Automatic Number Plate Recognition (ANPR) cameras placed strategically on roads entering and exiting the congestion zone can either be equipped with optical road-side processing units or with centralized processing at the control center.

Success Story

Tehran Congestion Charging Zone: Context Implementation of FANAP’s software allowed for completely automated control and management of Tehran’s congestion zones. Approaches: • Multi-lane ANPR cameras for processing plate numbers of all entering vehicles • Traffic control center • Database to update policies and status of vehicles • Automatic billing systems
