摘要
Big data of urban public transportation contains rich spatial and temporal information, which is the data basis for passenger travel characteristics analysis and evaluation of urban transportation service capacity. In this paper, we take the big data of Beijing bus swipe card and taxi track as the research object, store and calculate these two types of big data based on Hadoop distributed system, build the calculation model of passenger flow extraction, extract the hot ride areas and establish the visualization system based on WebGIS for the visual expression of data analysis results.
