Map Visualization Of City Traffic Big Data

For the development of intelligent transportation and the vast collection of data around,there is a huge potential and value in urgent need of processing and mining.Accurately grasp the characteristics of the era of big data,in-depth analysis of the impact and the role of intelligent transportation,to improve traffic conditions in the country to new heights and has a very important starting point.However,how to analyze and use these massive and complex data becomes a challenge.Visual analysis technology provides us with a direct and effective way.It complicated traffic data and analyze results visually intuitive to show up,and support for the results of the screening and interactive browsing.In addition,when people from the visual image generated found some of the expected or unexpected features too,you can also start the analysis algorithm to automatically dig targeted traffic information.This article focuses on the processing of traffic data and large geospatial data visualization theory,usinng map visualization analysis method to analyze traffic data visualization.The main contents of this article are:(1)A review of the extensive literature on big data and map visualization applications in urban transport will be understood that the proposed use of big data processing and data mining visualization technology method data traffic map visual analysis;(2)Based on the principle of boids algorithm uses js to achieve its animation technology,and applied to simulate the effect of traffic.(3)Based on Hadoop big data processing and storage technologies Hbase efficient processing and storage buses,taxis,subway data,build a data warehouse.(4)Based on SOA service-oriented programming,the use of open source frameworks MyBatis,Spring,Struts2 write traffic data publishing interface.(5)Designed and implemented based on open-source mapping framework Leaflet,and open source graph framework d3.js: Based visualization road speed taxi GPS point;based on site traffic visualization bus card data;based on traffic data and bus lines speed visualization;based on the number of site traffic metro card data visualization;OD traffic flow based on regional traffic and travel time visualization.Through the large data storage and processing technology,the taxi data,bus data,metro data efficiently processing and storage,and data warehousing,and the use of data mining visualization technology visualization of traffic data,design and implementation of traffic data visualization for traffic analysis method of map visualization of large data provided by reference.
