A Service Oriented Geoprocessing System for Real-Time Road Traffic Monitoring

Abstract

The emergence of the Sensor Web has paved the way for a new set of innovative software applications that exploit the enhanced availability of real-time information. This article describes one such application built from Sensor Web components that aggregates GPS track data from a fleet of vehicles to provide an overview of road traffic congestion at the city scale. The application embodies a Service Oriented Architecture; web service components are used to archive and pre-process incoming sensor observations, to encapsulate a horizontally partitioned spatial database that performs geoprocessing, and to disseminate results to client applications. Our results confirm that floating car data can ..
