Tokyo's Metropolitan Expressway will adjust tolls for private vehicles during next year's Olympics and Paralympics, charging more when events are held and less in the early hours, the metropolitan government and games organizers said Monday.

Under the road pricing system, ¥1,000 ($9.50) will be added to regular tolls in Tokyo from 6 a.m. to 10 p.m. during the events. Buses, taxis, trucks and pre-registered assistive vehicles for people with disabilities will be exempt from the surcharge, they said.

In a bid to encourage logistics companies to use roads late at night and early in the morning, tolls on the expressway across downtown Tokyo will be halved from midnight to 4 a.m. for vehicles equipped with an electronic toll collection device, or ETC, they added.
