Gao De, the leading provider of digital maps, navigation and location services solutions in China, officially released the “Analysis Report on Major Cities in China in the Third Quarter of 2014†in Beijing on December 3. The report shows that in the third quarter, the national key cities were ranked first in Beijing, followed by Hangzhou, Shanghai, Fuzhou, Dalian, Jinan, Shenyang, Wenzhou, Guangzhou and Zhengzhou. At the same time, in response to the single-double problem of wide attention, Gaode also released data that the single- and double-number limit during the APEC period was 38% lower, and the congestion situation was greatly eased.

Congested in Beijing, Dalian's new list of Gaode traffic reports: In the third quarter, Beijing's congestion ranked first in the country, the all-day congestion delay index was 1.74, and the peak congestion delay index reached 2.12, meaning Beijing used private cars. Office workers need to spend 2.12 times in non-congested state to reach their destination. The cost of congestion is the highest in the country. The impact of the September school season plus smog and rainy weather may be the reason why Beijing became the first city this quarter.
At the same time, Shanghai's congestion rankings in the last quarter were slightly lower due to the congestion delay index in this quarter, and the congestion ranking fell to third place. The TOP10 ranking of the congested cities this season is newly listed in Dalian, Wenzhou and Zhengzhou. Among them, the congestion rankings of Dalian and Wenzhou surpassed the mega city Guangzhou, and Dalian entered the top 5, which was seriously congested during the peak period of commuting. The traffic congestion in second-tier cities cannot be underestimated, and there is a tendency to catch up with first-tier cities.
Whether the big data to explore the feasibility of single or double limit is particularly relevant to the impact of Beijing's implementation of single and double number restrictions on urban road conditions during APEC. The report shows that during the APEC period, Beijing implemented the single and double limit policy to reduce the peak congestion index of the city during peak periods. 38%, the speed increased from the original 22.00 km / h to 35.05 km / h, the congestion situation has been greatly eased, the entire road network is basically smooth, the average speed of the city peak period increased by 60%. In addition to the sky "APEC Blue", the urban road network also features "APEC Green".
After APEC, Beijing's brewing of single and double numbers was normalized. According to the online voting initiated by People's Daily, 54.9% of netizens voted in favor, and 44.1% of netizens voted against it. The Gaode Traffic Report provides a timely and objective data reference for the feasibility of demonstrating whether the single or double limit policy is feasible through big data. It is understood that the Gaode Traffic Report collects data based on Internet crowdsourcing ideas, and uses 300 million high-definition map navigation users as data blueprints, supported by floating car data, focusing on the study of urban congestion assessment, congestion causes and solutions for the public. Provide advice to avoid congestion and help the government to block decision-making. Referring to the traffic report, the parties can be more rational when it comes to the feasibility of the single and double limit policy.
New breakthroughs in the report: The first set of treatment plans released the indicators of the Gaode traffic report to help improve the transparency of road traffic information, but only presenting problems to mitigate traffic congestion has little effect, the public needs to be able to guide them to avoid The method of congestion. In the traffic report of the third quarter, Gaode and Tsinghua University-Daimler Sustainable Transportation Research Center selected the quarterly traffic congestion sections of key cities to carry out in-depth analysis of the causes and mechanisms of congestion, and provided ideas for the improvement of governance policies. in accordance with. As found in the study, more than 90% of the normal congestion mainly occurs in the rapid road entrance where a large number of vehicles flow in, and it is preferred to set a longer buffer zone during urban construction to avoid conflicts between the incoming traffic and the main traffic. Congestion; set traffic flow at key entrances and exits; road sections that cause congestion in illegal parking (such as primary school intersections), increase manpower for traffic guidance, and narrow access roads; increase parking spaces in the vicinity of business districts, improve traffic from the source of urban road network construction pressure.
(Note: The Cube map is used to show the time-space distribution of the average speed of the vehicle over a long period of time. Each unit cube represents the average speed of the vehicle at a certain position on the road within 5 minutes of the day)
Dong Zhen, vice president of Gaode, said: At present, the real-time traffic information service of Gaode map has covered 114 cities across the country. Users can view the road condition information in real time by opening the map of Gaode, and can realize intelligent avoidance by selecting the function of “avoiding congestionâ€. Route planning to improve travel efficiency. It is understood that the penetration rate of real-time traffic information in China is only 5%, while the penetration rate of real-time traffic information in many developed cities abroad has reached 70%-80%. The real-time traffic information service of Gaode map and the release of Gaode traffic report are all The construction of urban intelligent transportation provides new ideas.
