Abstract:
Trajectory analysis is an important research area. It focuses on the analysis of trajectories of various kinds. The current project focuses on the development of traffic analysis system which can be used to find micro and macro insights about vehicle mobility. A dataset downloaded' from "kolntrace.project.citi-Iab.tr" was used for the development of the system. This project helps to make calculated decision about vehicle mobility throughout the city. This project is a prototype and we use the dataset of Germany city Cologne. The project has two major parts; part one is related to data processing by using Hortonworks Sandbox, In this phase we have used Hadoop tools PIG, HIVE and HDFS file system. Mainly all the processing is done in PIG script. The extraction of this process is to find out presence of vehicles in a specific area and find number of vehicles in hourly manner in whole city. Along this similarity-based queries are applied between velocities of two vehicles. In addition to this velocity can be calculated for one vehicle. For the storage purpose of the output we use Hive tables. The other part is data visualization for this purpose; we made as ASP.NET MVC application. We used C# as a blackened language and use AngularJS, JavaScript for frontend languages. We visualized the vehicle x-y coordinates on google map API and draw the full path covered by the vehicle. For the presentation of data insights on graphs we used chart.js JavaScript library.
