Recently, a well-known navigation company released the “Report on the Analysis of Major Cities in China in the First Quarter of 2015”. Among the 45 key cities in China, Beijing ranks first, followed by Shanghai, Jinan and Hangzhou, and Nanjing ranks 26th. . A year ago, the company released the first quarter of 2014 urban traffic analysis report, Nanjing ranked sixth. In one year, the ranking of Nanjing dropped from the sixth to the 26th. For this situation, a person in charge of the company called it “Nanjing phenomenon”. Why is the road traffic situation in Nanjing so great? Recently, the reporter of Modern Express interviewed the Nanjing Traffic Management Bureau.
Data Nanjing congestion ranking dropped from 6 to 26
Last year, a well-known navigation company launched China's “Top Ten Blocks” for the first time. It used 300 million navigation users as the data blueprint. Based on this, it calculated the national congestion city ranking based on big data. Specifically, it is to compare the actual time spent in normal cities to compare the actual time spent in major cities in China, and to obtain a ratio. The higher the ratio, the more serious the traffic jam in the city. For example, the average road length of 10 minutes, in a city takes 30 minutes to complete, then the ratio, that is, the congestion delay index is 3.0.
In the first quarter of 2014, the first congestion ranking released by the navigation company showed that the congestion delay index in Nanjing was 2.29, the usual delay time was 21.74 minutes, and the usual speed was 24.18 km/h. In the second quarter of the same year, the data showed that Nanjing had withdrawn from the “Top Ten”. In the third quarter, in the cities participating in the rankings, it has already retreated to the 21st place, which means that the congestion situation in Nanjing has been greatly improved. In the first quarter of 2015, Nanjing’s congestion rankings dropped further, ranking 26, with an all-day average congestion delay index of 1.48.
There are more and more suspected cars, why is the road getting better and better?
It is worth mentioning that in the whole year of 2014, the number of cars in Nanjing increased from 1.46 million at the beginning of the year to 1.72 million, and this data is still increasing. In March of this year, this number has risen to 1.8 million. “On average, 1,000 new cars are on the cards every day.” A staff member of the Nanjing Vehicle Management Office told reporters. While the car ownership is increasing, why is the traffic congestion in Nanjing still getting better? In response, a traffic control person said in an interview that this is inseparable from road construction. “Since 2014, the three rapid loops that have been transformed have created new changes in the traffic pattern.”
The three fast loops have obviously made the speed faster. With the official completion of the Chengbei Expressway in 2014, the last node of the Jiangnan Ring has been opened. At present, Nanjing has formed three fast loops, namely, the Inner Ring, the Ring Road and the Jiangnan Ring. The more citizens choose the road that suits them best. It is understood that at the end of 2013, the average daily traffic volume of the ring road was only 50,000. Today, this number has reached 117,000, and the traffic volume in Jiangnan Ring is gradually rising. This means that a new traffic pattern is gradually taking shape, and the traffic pressure on each road is also becoming more balanced.
Ms. Wang, who lives in Jiangning, because the work unit is in the Olympics, she has to go to work on the street every day, and the peak of Yingtian Street is blocked. On March 16, 2014, the Shuanglong Street toll station was removed. The Nanjing Ring Road officially became a real urban road, diverting many vehicles that were originally used from the congested sections of Yingtian Street. Today, Ms. Wang works from the ring road, although the journey is a few kilometers more than the original, but it takes only 40 to 50 minutes to reach the unit.
Taking advantage of the "Qingao" opportunity to vigorously develop road construction interviews Modern Express reporter learned that last year the government departments seized the opportunity of the "Young Olympics" development, vigorously carried out urban road construction, and built a channel network structure to enhance road capacity. Around the city's main traffic nodes, the Nanjing Traffic Management Department has organized special forces to carry out analysis and analysis of easy-blocking nodes and implement “one point one policy” governance. Up to now, a total of 260 traffic jams have been adjusted, and 10 nodes such as Children's Hospital and Zhongshan Gate have been effectively treated, and the traffic efficiency has been significantly improved.
At the same time, accelerate the construction of the bus network. Last year, 12 new bus lanes were added in the city, and the bus lines of the main axis of the main city were all connected. The main roads of the Hexi area were covered by the bus network. The traffic control department also made full use of the traffic signal networking and ground bus priority control system, and took the lead in realizing the priority of three trams and 600 buses in Jianye District. When the bus arrives at the intersection, the traffic lights will be extended according to the traffic conditions at the intersection. The green time or the red light time is shortened to facilitate bus traffic.
In addition, in order to effectively alleviate the impact of “parking difficulties and parking chaos” on urban traffic, the Nanjing Traffic Management Department has focused on parking management problems and has strengthened its management from both sides and barriers. On the one hand, in-depth exploration of road parking resources, a total of 22065 new berths in the six districts of Jiangnan (8978 main and secondary roads), 2025 free berths for the main and secondary roads, and 490 limited parking berths in front of the school. Set 8 micro-cycle zones, 15 single-row lines, and excavate 493 berths in the road. On the other hand, the implementation of localized assessment, socialized cleaning, linkage law enforcement and leveraged fees, the implementation of the "100 yuan 3 points" ceiling penalty for the main and secondary roads, all comprehensively promoted the city's parking environment optimization and upgrading.
At present, the traffic control hall of the Traffic Management Bureau has also launched a two-level inspection mechanism for video surveillance. Based on 24 high-altitude monitoring, the overall inspection is carried out. In the case of the police, the ground monitoring with 1323 is used to confirm the situation, and the nearby police and rapid disposal ensure the urban road traffic. Safe and smooth.
