Real-time bus application "Here comes the car" precise tillage data accuracy

The car's coming. is a real-time bus app, based on the common "public transport electronic Bus stop" function, designed to allow users no longer confined to the bus station, but at any time can know to wait for the bus and a few stops, so as to decide when to wait for the platform, to solve people in all kinds of bad weather waiting for a long time, the difficulties of hardship.

The car came to be divided into line inquiries, site inquiries, peripheral lines, line collection of several major functional modules to cover users of a variety of bus information query needs. This means: In addition to the basis of the line, site, transfer inquiries, the car is also able to inquire about each line on every bus on the real-time location and all the vehicles through the waiting station vehicle arrival information, more through the surrounding site function quickly locate the current location and the surrounding site information.

In fact, the real-time bus application is not a new thing. Before the car came, Baidu, Gould and other large map of the large have been added to the real-time Bus information query module. However, the car has come to the rapid growth in this, from 2013 since the establishment of the company has accumulated about 6 million users. At present, in this product homogeneity degree is higher than the field, the car comes the core competitiveness is what? Its founder, Shaoling, told 36 Krypton that it is the technology that is the algorithm for data processing and operation.

It's coming. With the bus company and the relevant government departments, in the bus installation of GPS equipment, access to the bus location information. However, the public transport system itself is relatively weak in information: On the one hand, its traditional system of the station is very low precision; On the other hand, even if the GPS installed, its return data can not reflect the transit process of various unconventional operating conditions. Therefore, to provide users with real-time public transport information, we must overcome the data error, the specific error includes the following aspects:

Data return frequency problem. If you want to do real-time, the data return frequency should be guaranteed in 10-15 seconds, but many buses often do not, and therefore can not meet the requirements of this type of application information processing requirements.

The drift of geographic information. Sometimes, GPS return the location information maximum drift range can reach 200 meters, which need to rely on algorithms to identify and solve.

Data loss problem. When the bus passes through bridges, tunnels and other signals that cannot be covered, data loss will occur. At this time, also need to pass the corresponding technology to identify, and the data to fill up.

Transit into unconventional operating conditions. Unconventional operating conditions include vehicle failure, vehicle refueling, vehicle return field, vehicle line changes, and many other conditions. In these cases, the vehicle is still running, the location of information back, but not according to the original time to enter the station, so also need to identify in time.

At present, the car came to the algorithm analysis team of about 10 people, the daily need to deal with the amount of data reached 100 million. But Shaoling very confidently told 36 Krypton, according to their investigation, the car came to the accuracy of data in Hangzhou than Baidu 30% higher.

At present, the car has been covered to more than 10 cities, including Tianjin, Qingdao, Wuhan, Zhengzhou, Suzhou, Hangzhou, Dongguan, Shenzhen, Chengdu, Chongqing, Urumqi. I was wondering why the car would first choose to expand from the second-tier cities. Shaoling said that in the electronic aspect of public service, second-tier cities are better than first-tier cities and more suitable for further mobile internet. For this point, from the second-tier city of my mid-Autumn Festival home has fully felt the home of the public transit site electronic information is indeed better than Beijing to improve a lot. Moreover, the Government of the first-tier cities has performed more cautiously in municipal construction, and the barriers to cooperation have been relatively higher.

Before, there are rumors that the car came to be Tencent to buy 30 million of dollars, Shaoling again denied this claim. And he told 36 Krypton that the car had just got a 5 million dollar a round of financing, but did not disclose the investor's information. Before this, Lei and Xiaoping participated in the Angel Round investment, investment amount of about millions of yuan.

After getting the financing, the car will continue to improve the technology, and in the server and bandwidth to do the corresponding input. In addition, it is for the nationwide expansion of the market. How will the business model expand in the future? How will the business model be built? Shaoling said that these are still in the discussion stage, and there is no very shaped ideas. A more likely direction is the use of NFC to achieve mobile payment for public transport, I do not know whether it will be with the Alipay wallet "mobile phone card" service cooperation? Now Apple has released its Apple Pay, which will undoubtedly give the car more room for mobile payments. In the future, cars are coming. It is likely to expand to the O2O domain based on the locking of the city's users because their users have very specific location characteristics.
