天气影响的城市交通实验平台设计与实现

Development and implementation of urban traffic trajectory processing effected by weather

设计并完成了一个B/S结构的天气影响的城市交通实验平台。首先对出租车定位数据进行预处理,包括统计上下客坐标、上下客时间等。然后将数据映射到公开地图Open Street Map中进行可视化展示,确定了机场区域和地铁口区域,设计了机场车流量分析和地铁口车流量分析模块,筛选指定区域内的出租车出行数据。在此实验平台上,利用ASP.NET、Java Script等技术实现分析与统计结果以图表展示。

A B/S structure of urban traffic weather impact experimental platform was designed and completed.First of all,processing of the taxi global positioning system data includes the upper and lower passenger coordinates,passenger time of getting up and getting off.Then,the data are mapped to OpenStreetMap for visual displaying according to different data processing methods.Our experiments include two models:airport traffic flow analysis and metro traffic flow analysis.We screen the specified area of the taxi travel data.In this experiment platform,the use of ASP'NET,JavaScript and other technologies to achieve the analysis and statistical results of the chart to meet the needs of a specific re?gion,a specific period of time to display the data.
