Recently, Gaode Map, together with the Big Data Development Department of the National Information Center, Daimler Joint Research Center for Sustainable Transportation in Tsinghua University and other authoritative organizations, released the Traffic Analysis Report of Major Cities in China in the Third Quarter of 2121 (hereinafter referred to as the Report). The data shows that among the 361 cities monitored by Gaode Traffic Big Data, 7.48% of the urban commuting peaks are congested, 58.17% of the urban commuting peaks are slow, and the remaining 34.35% of the urban commuting peaks are unblocked. The Pearl River Delta region has the highest degree of congestion in the major economic regions in China, while the peak congestion delay index in the Yangtze River Delta region is 1.49, which is lower than the national level of 1.56, and the traffic situation is relatively good.

In the third quarter, the year-on-year congestion in Urumqi dropped the most

Among the 361 cities monitored by Gaode Traffic Big Data, 7.48% of the urban commuting peaks were in a state of congestion, 58.17% were in a state of slow travel, and the remaining 34.35% were in a state of smooth traffic. The Pearl River Delta region has the highest degree of congestion in the major economic regions in China, while the Yangtze River Delta region has the best traffic condition with a peak congestion delay index of 1.49, which is lower than the national 1.56.

in the third quarter, among the 51 major cities monitored by traffic big data of gaode map, the congestion delay index of 6% cities decreased year-on-year, 28% cities were basically flat, and 66% cities were congested. Affected by the epidemic, the city with the largest year-on-year decrease in congestion was Urumqi, followed by Hohhot and Luoyang. The congestion degree of Hohhot in 2119Q3 was higher due to abnormal weather, and the congestion decreased by 6.63% this season. The city with the largest increase in congestion is Qingdao.

In the third quarter, the happiness index of ground bus travel in Ningbo was the highest

Ground bus is an important part of urban traffic, which can evaluate the traffic level of a city more comprehensively and objectively. Originated by Gao De? "Happiness Index of Ground Bus Travel"? It can comprehensively evaluate the operation status of urban ground bus.

in the third quarter of p>2121, the happiness index of ten cities, including Ningbo, Shijiazhuang and Tianjin, was relatively high, indicating that the comprehensive performance of bus operation efficiency, reliability and relative urban traffic level was better. Among them, the happiness index of ground bus travel in Ningbo is the highest, which is the closest to the positive ideal value, reaching 79.19%; Tianjin and Nanjing rank first in the "happiness index" among megacities and megacities respectively. At the same time, Ningbo has the smallest "all-day line operation speed fluctuation rate" and the most stable bus operation efficiency.

The bus efficiency in Xiamen is the closest to that of cars, and that in Ningbo is the most stable

Comparing the bus operating speed with the speed of social vehicles in the same period and line can directly and objectively reflect the relative level of bus operating efficiency and urban traffic efficiency, and the smaller the value, the smaller the speed gap between them. During the third quarter, the "social vehicle-bus speed ratio" in the core area of Xiamen city is the smallest, that is, the bus efficiency in Xiamen is the closest to that of cars, and the speed of cars is 1.847 times that of buses; Except Xiamen, the speed ratio of Shijiazhuang, Zhongshan and Changsha is less than 2.

The average waiting time in Lanzhou is the best

The overall waiting time in megacities, megacities and large and medium-sized cities is almost the same. Among them, the part of megacities and large and medium-sized cities affected by departure frequency showed a downward trend, while the part affected by traffic disturbance generally increased slightly, and the bus frequency gradually resumed, and the urban traffic operation returned to normal; The waiting time in the two parts of megacities has not changed much from the previous month, and the traffic operation of public transportation is relatively stable.

within the scope of the cities studied, the waiting time in Lanzhou is 5.3 minutes, which is the best among all cities. Chongqing and Chengdu are the first megacities and megacities respectively, and the impact of departure frequency and traffic disturbance is the lowest among similar cities. In addition, the waiting time in Shenyang decreased the most, and the level of public transportation services improved.

Xi' an has the lowest traffic health index of 42.81% in the third quarter, while Nantong has the highest traffic health index

Will the "traffic health index" of 51 major cities in China be? As the critical value of health and sub-health, that is, the health horizontal line, the average value is obtained, and the list of traffic health and sub-health is obtained. The data shows that the traffic health index in Xi 'an is the lowest, and the urban traffic is relatively in a sub-health state, and its traffic health index is 42.81%. Nantong has the highest traffic health degree, and its traffic health index is 74.96%. Compared with the third quarter of 2119, Harbin's traffic health became better in the top ten of the traffic sub-health list, up by 12.64% year-on-year; The traffic health index of Luoyang City in the TOP11 traffic health list has improved significantly, up by 7.98% year-on-year. These data analysis can assist the formulation of relevant transportation policies and travel solutions.

at the same time? Hohhot ranked first in the city where the traffic health index improved year-on-year, and its six indicators all improved year-on-year; Xi 'an ranked first in the city where the traffic health index decreased year-on-year, and its six indicators all deteriorated year-on-year.

cities with more than 4 million cars: Suzhou has the highest traffic health index

To measure and compare the traffic operation in different cities, we should fully consider the differences of traffic development scale between cities. ? According to the national car ownership data released by the Traffic Management Bureau of GA as of September 2121, the report divides cities into four grades: "over 4 million", "over 3 million", "over 2 million" and "under 2 million" to comprehensively consider the inter-city traffic situation. The data shows that Suzhou has the highest traffic health index and Chongqing has the lowest. Among the cities with more than 3 million vehicles, Tianjin scored the highest and Xi' an scored the lowest; Among the cities with over 2 million vehicles, Tangshan scored the highest and Guangzhou scored the lowest; Among the cities below 2 million, Nantong scored the highest and Changchun scored the lowest.

The list of parking delays at traffic light intersections is released: Dongguan? Foshan? Shenzhen ranks in the top three

According to the monitoring of the traffic evaluation system of "Spiegel" on the map of Gaode, half of the cities in the Yangtze River Delta and Pearl River Delta regions have delayed parking in the morning and evening peak hours at important intersections of major cities in China, and the southern cities are the main ones in the TOP21 of the queue length at traffic lights, and most of the indicators in large and medium-sized cities are on the rise. In the third quarter, the top three cities for parking delay were Dongguan, Foshan and Shenzhen, which were consistent with the second quarter. It was found that the parking delay in Shenzhen was significantly reduced, while that in Dongguan and Foshan increased slightly. The top three cities in the queue length of intersections are Xi 'an, Guiyang and Guangzhou, which are consistent with the second quarter; It was found that the queue length in Xi 'an was basically the same, while that in Guangzhou and Guiyang increased slightly.

expanding the ranking of traffic light intersections monitoring for parking delays, we can find that the top 111 traffic light intersections are distributed in 31 cities, among which Shenzhen has the largest number of intersections, but none of them are ranked in the TOP21.

The top ten cities with low service level at traffic light intersections: Dongguan, Shenzhen and Changchun rank in the top three

What is the comprehensive calculation by mining traffic big data of Gaode map? The "intersection delay index" evaluates the intersection service level of 51 cities in China based on the number of stops with equal light duration, and divides the intersection service level into six grades A-F (A is the best and F is the worst) according to the delay index. When there are many intersections with E and F grades in cities, it shows that the overall intersection service level is low.

the data shows that the cities with relatively low service level in the morning and evening rush hours in the third quarter are mainly distributed in the Pearl River Delta, and the top three cities are Dongguan, Shenzhen and Changchun, accounting for 11.11%, 7.99% and 7.13% respectively, including 143 grade E and F intersections in Dongguan, 196 in Shenzhen and 67 in Changchun.
