Acquisition, filtering and toll data processing system for obtaining origin-destination matrix and travel times on highways

摘要

This paper presents an acquisition, filtering and real-time toll data processing system that provides a base for resolution and generation of studies and models of behavior on highways. Crossing points estimation, speed calculation, study traffic flow, travel time estimation and stopping points can also be provided. The complexity of processing with supplied data volume makes indispensable a less relevant information filtering. This filtering can be done through indicators such as speed or nullity of fields and a performance improvement job in database level using views, materializations, partitioning and parallelism. A web application called MODA has been developed. This application make easier and faster forecasting and Spanish highway maintenance tasks, improving the quality of roads and help to know the reasons for which incidents happens in order to put them a viable solution thanks to studying data and graphics provided. The data model, data extraction and filtering process, the application architecture, the software design and implementation model are described in detail.
