Tolls and Payment Means


Shadow Toll

A Shadow Toll is a transport infrastructure financing model in which the toll is not paid by the users of the infrastructure themselves, but by the government or public administration.

The cost of this toll is calculated according to the number of users or vehicles using a road, bridge or tunnel, hence the need to implement a technological solution that detects and classifies vehicles in normal motion.

The infrastructure operators can use the data from the toll system to generate the corresponding invoices to the public bodies responsible for payment of the toll.

The Shadow Toll model seeks to encourage private investment in the construction and operation of roads, while ensuring their maintenance and quality. Shadow Tolling is also sometimes used to transfer the financial risk to private operators, and implementation varies according to project – and country – specific conditions.
