The coronavirus outbreak is giving city authorities an opportunity to implement congestion pricing to curb traffic and pollution, urban experts said, even as the pandemic has forced Singapore to put its new satellite-based fee system on hold.
Congestion pricing, which charges private vehicles entering the city's busiest areas, was first introduced in Singapore in 1975.
London, Milan, Oslo and Stockholm are among the cities that also have a charge, with New York City planning to introduce one from 2021. Dozens of other cities have signaled interest.
