Скачать или смотреть China-made "zipper truck" runs to ease urban traffic jam in east China

Jinan, capital of east China's Shandong Province, has started using a "zipper truck" this week which can redesignate traffic lanes during rush hours to ease congestion.
Lyuyou Road is generally configured with three westbound lanes and three eastbound ones. In half an hour, according to the time of day the road is converted to a 4-2 formation. The lanes will be realigned between 5 p.m. and 7 p.m. on weekdays.
The median barriers, essentially a chain of linked barriers, were specially made for the truck. Each weighs more than 50 kilograms. Every 20 or 30 are linked together.
In many cities like Beijing, Nanjing and Changsha, the idea of relocating traffic lanes during commute periods is not new. But traditionally, the traffic lanes were usually relocated manually, which was laborious and time-consuming.
