THE city's congestion-severity ranking among Chinese cities has dropped to 28th, according to a recent congestion index released by www.amap.com.
Shenzhen is the least congested of the first-tier cities, following Beijing, Guangzhou and Shanghai, thanks to the opening of more Metro lines and a package of measures enacted by traffic police to improve traffic.
Acting on the big data of the platform of Didi - the country's leading app-based taxi service provider - which had identified the most congested road sections in the city, Shenzhen traffic police set up taskforces to enhance 478 congested areas and road sections through traffic improvement methods. The severity of congestion in Luohu, Futian, Yantian, Longhua, Nanshan and Dapeng has been reduced.
In the second half of last year, Shenzhen police unveiled 10 traffic organization methods to relieve congestion, including setting up a continuous flow intersection, also known as the displaced left turn, at the intersection of Caitian Road and Fuhua Road in Futian District, all left-turning lanes at the intersection of Jichang South Road and Bao'an Boulevard and a green light coordinating system on Guangqiao Road.
The opening of Metro lines 7 and 9 in October 2016 also helped relieve traffic congestion in the city in 2017.
The two lines now handle about 730,000 riders a day.
Currently, eight Metro lines - 1, 2, 3, 4, 5, 7, 9 and 11 - are operating in the city, transporting an average of 5.3 million riders a day.
Meanwhile, more bus lanes have been designated across the city by the traffic police authority, which encourage more residents to give up private cars for commuting as it is faster to take a bus.
