The term "big data" was first written into the government work report at the 2015 National People's Congress. In the field of transportation, big data has been regarded as a technological tool to ease traffic pressure. The application of big data helps to understand the patterns and causes of people's travel in urban traffic congestion problems, realize the harmony between transportation and life, improve the livability of the city, and provide comprehensive decision-making based on data evidence for the government's precise management.
With the development of cell phone networks, global positioning system (GPS)/BeiDou vehicle navigation, vehicle networking, and transportation Internet of Things (IoT), the information of transportation elements such as people, vehicles, and roads can be collected in real time, and the sources of big data on urban transportation are getting richer and richer. With the technical support of the increasingly mature Internet of Things and cloud computing platform, through the collection, transmission, storage, mining and analysis of urban transportation big data, it is expected to realize the integration of urban transportation, i.e., to realize the integration and optimization of the administrative supervision of transportation, the operation of transportation enterprises, and the service of the transportation citizens on a single platform.
1, live, make good use of big data is to improve the road to transportation
In recent years, the domestic large and medium-sized cities have begun or brewing and transportation big data related projects, such as public transport metropolis, urban transportation data center, intelligent transportation, traffic operation coordination command center, a large number of projects on the big data technology demand is also increasing. The demand for big data technology is also increasing.
The popularization and promotion of big data technology in the industry started in 2011, and after two years of development, big data technology has become popular in the field of intelligent transportation. Based on the application of big data technology and related business, the wide application of revitalized data will be the hotspot for the development of domestic transportation big data in the next few years.
2, intelligent transportation big data management platform application is the core
While big data technology is currently in the field of intelligent transportation development prospects all the way to the good, but the big data technology is still faced with a number of problems in the actual use. One of the main problems is: in the face of diverse, closed operating environment, how to collect and manage traffic data? How to ensure the quality of data? How to apply it quickly? This is the governments, transportation companies, transportation system integrators **** with the problems faced.
The application of intelligent transportation big data management platform will effectively solve these problems. Intelligent transportation big data platform mainly includes five aspects: urban transportation information data system, urban transportation integrated monitoring and early warning system, urban transportation carbon emission real-time monitoring system, public transport urban management system, public travel information service system.
Urban traffic information data system is based on big data application technology of the transportation industry information **** enjoyment exchange center, after the establishment of the data center, will become the hub of urban traffic information.
City traffic comprehensive monitoring and early warning system can realize real-time monitoring of the whole city traffic condition. The traffic management department can make effective prediction of possible large-scale traffic paralysis in urban traffic. At the same time, the system can also guide the public travel, provide comprehensive and timely travel information for the public, and truly achieve the travel requirements of green transportation.
Intelligent travel, also known as intelligent transportation, refers to the use of mobile Internet, cloud computing, big data, the Internet of Things and other advanced technologies and concepts, the traditional transportation industry and the Internet for effective penetration and integration, the formation of a "reasonable distribution of online resources, offline efficient and high-quality operation" of the new industry and a new model, and the use of satellite positioning, mobile communications, high-performance computing, and the use of the Internet. Satellite positioning, mobile communications, high-performance computing, geographic information systems and other technologies to achieve real-time perception of the state of urban and intercity road traffic system, accurate and comprehensive traffic conditions, through mobile navigation, roadside electronic bulletin boards, traffic radio and other ways to provide people. Among them, Dimension Intelligent Transportation is a high-end intelligent transportation solution relying on Dimension Technology's rich development experience and strong technical accumulation in the fields of cloud computing, Internet of Things, big data, artificial intelligence, financial technology, and other innovative business models in the field of intelligent travel. On this basis, it integrates real-time sensing and analysis technology of driving behavior, realizes multi-mode and multi-standard dynamic navigation for public travel, and improves travel efficiency; and assists the traffic management department in formulating traffic management solutions, promoting urban energy conservation and emission reduction, and enhancing urban operational efficiency.
Baidu Maps uses cloud computing and big data analysis technology to provide users with information on congested sections of national highways during the Spring Festival, traffic flow at important nodes, as well as accident-prone road inquiries through data visualization in the form of the "Safe Broadcasting" website, which provides users with a reference for their travels.
At the same time, Baidu Maps launched a mobile version of the page suitable for cell phone viewing, so that users can view authoritative national highway traffic information in real time through their cell phones even when they are on the road. Gaode Maps, on the other hand, released a Spring Festival travel forecast report on Spring Festival travel, which analyzes the calculation of net migration in/out of cities in previous years, and anticipates high congestion highways and tourist attractions with more tourists this year for the public's travel reference. Both sides rely on big data analysis as a cure for congestion, "Internet +" transportation is imperative.
"Internet +" the core of the traffic is still in the data, which map data and big data analysis capabilities of the strongest, who will achieve the greatest market advantage. Data service economic and social era, how to make big data to release the maximum value has become imperative, and the analysis of big data has become a prerequisite to enable it to fully realize the value, which puts forward a higher demand for IT system computing power and challenges. In this context, the market demand for 4-way and more than 4-way server has grown significantly, and more and more industry users are beginning to use high-end servers to meet critical business needs.
