【摘要】：随着城市发展进程的加快,交通拥堵问题日益严重,已经严重影响到了居民的出行,解决交通拥堵问题迫在眉睫。而解决交通拥堵问题的关键技术就是交通信息的采集。大数据和“互联网+”已成为了时代发展的前沿,手机移动端成为信息交互的重要手段。本文依托手机android软件app系统平台,针对用户出行信息,通过百度SDK定位包完成了手机定位数据读取,并对数据进行清洗、处理得到有效数据,再对有效数据进行可视化表达。主要研究内容如下:首先对手机定位技术原理实现进行了研究,在分析常用的手机定位技术的基础上,针对交通拥堵问题提出了采用A-GPS的交通移动数据的定位方法。其次通过对时空数据的研究,设计了时空数据的采集系统,进行了基于Android系统平台的数据采集app系统的开发。最后对采集到的数据进行清洗和预处理,并在可视化平台界面ArcGIS中进行了二维的数据表达。为了验证系统的可靠性和准确性,选择位于吉林省长春市的中心城区多个重点拥堵路段进行了系统测试。测试结果表明本文采用的定位技术及数据处理技术对处理交通拥堵问题是有效的,对解决交通拥堵问题具有现实的工程意义。
[Abstract]:With the acceleration of urban development, traffic congestion is becoming more and more serious, which has seriously affected the travel of residents, so it is urgent to solve the problem of traffic congestion. The key technology to solve the problem of traffic congestion is the collection of traffic information. Big data and Internet have become the forefront of the development of the times, mobile phone has become an important means of information interaction. Based on the mobile phone android software app system platform and the user travel information, this paper completes the reading of mobile phone location data through Baidu SDK positioning package, and then cleans the data, processes the effective data, and then visualizes the effective data. The main research contents are as follows: firstly, the realization of mobile phone positioning technology is studied. Based on the analysis of common mobile phone positioning technology, a traffic mobile data location method based on A-GPS is proposed to solve the traffic congestion problem. Secondly, through the research of spatiotemporal data, the acquisition system of spatio-temporal data is designed, and the data acquisition app system based on Android platform is developed. Finally, the collected data is cleaned and preprocessed, and the 2D data is expressed in the visual platform interface ArcGIS. In order to verify the reliability and accuracy of the system, a number of key congested sections in Changchun City, Jilin Province, were selected for systematic testing. The test results show that the location technology and data processing technology used in this paper are effective in dealing with traffic congestion problems and have practical engineering significance to solve traffic congestion problems.
