ERP in Sing

Electronic Road Pricing (ERP) is an electronic system of road pricing based on a pay-as-you-use principle. It is designed to charge use of the road during peak hours. In peak hours it costs S$ 1 to pass each ERP sign (that's how taxi driver explained to me).

Singapore was the first city in the world to implement such an electronic road toll collection system for purposes of traffic jam pricing. It was introduced in 1998. Wonder whether it would be ever introduced in Kiev.
