Based On The Use Of MapReduce Fisher Optimum Split Method On Bus Scheduling

In urban development, increasingly fast pace of modern life, car ownership increased year by year, and more and more crowded roads, so traffic is not more convenient, resulting in a serious decline in the socio-economic benefits, impede people's lives, rise in car ownership increased automobile exhaust emissions, which in turn causes the greenhouse effect and pollute our environment, these are not conducive to the development of the city. Public transport, energy-saving and environmental protection, reduce carbon dioxide emissions and can effectively reduce traffic congestion status, it is one of the important means to improve the atmospheric environment. Public Vehicle Scheduling plays a decisive role in the bus companies. For the majority of passengers to travel cheaper and convenient, reduce carbon dioxide emissions from energy savings, increase passenger satisfaction, efficient public vehicle scheduling is very important, and for buses with some reasonable time segment is one of the major research direction. With the explosive growth of data and cumulative so that we enter the era of big data, an urgent need for powerful data mining tools to gain valuable information. Can be implemented in the Apache Hadoop platform, cluster analysis, classification analysis of many data mining algorithms classical analysis, to a certain extent for the large-scale data mining provides a convenient analysis [5]. Bus management information system every day to produce large amounts of on-board GPS data, which need to be processed and analyzed on hadoop internet. In the bus segment with a reasonable time, not disrupt the temporal order, and most clustering methods in classification sample is mixed together in chronological order will disrupt, Fisher optimum partition method can not disrupt the chronological classification, but this huge amount calculated using the method in Hadoop MapReduce tasks on multiple machines break down operations for the data collection, drawn bus with reasonable lap time segment.
