新型居民交通出行调查辅助系统设计

A New Auxiliary System Design for the Travel Survey of Residents

利用移动设备、卫星地图等技术,采集居民的所在位置、出行时间、出行方式、出行目的等信息,关键在于面向普通居民的系统易于操作,反馈的数据信息分析合理,能够有效获取居民出行的各项指标。系统设计分为基于移动设备的软件开发和反馈的海量数据的分析两部分。移动设备的软件采用Java语言在Android系统开发,软件在手机上安装运行后不需要被调查者进行任何操作,有利于非交通专业的被调查者能够顺利开展调查。移动设备利用GPRS发送被调查者的位置信息到MYSQL基础数据库中,并算出距离间隔信息以及速度信息。结合GIS工具,将道路网、公交线网、建筑物属性、用地属性,将出行终点的经纬度对应的建筑物匹配到可能的出行目的,再结合用户停留时间得到精确的出行目的。出行起讫点则由出行距离,出行速度和是否经过城市道路网等条件判定。通过平均速度、瞬时速度以及出行的经纬度对应到GIS中的出行路径与公交线网比对,判断精确的出行方式,最后获得出行量分布。

To collect the travel information （i. e. , location, travel time, travel mode, and travel purpose） of residents using mobile device and satellite maps more efficiently, it is very important that the survey system is easily operated and the analysis on the feedback data is reasonable. The systematic design includes software development and the analysis of massive data. The software on mobile was developed using Java language in Android system. The software did not require any operation from the surveyed people after it was installed, which enabled the convenient implementation of the survey for the surveyed people without professional knowledge. Using GPRS, the mobile sent the location information of the surveyed people to the MYSQL database ; then the distance interval and velocity information can be calculated. Integrated with GIS, the road network, public transportation network, building properties and land use property were loaded into GIS. By matching the coordinates of the destination with the corresponding building and analyzing the time spent at the destination, the trip purpose can be obtained. The origin and destination of the trip were determined by the conditions of trip distance, velocity and whether they pass the urban road network. By analyzing the average velocity, instantaneous velocity, and the latitude and longitude with the trip route of GIS and the public transportation network, the trip mode can be determined and the distribution of trip volume can be obtained.
