viaRODOS: Monitoring and Visualisation of Current Traffic Situation on Highways

Abstract

Part 5: Industrial Management and Other ApplicationsInternational audienceThis paper describes methods of traffic monitoring based on on-line retrieval of big data both from cars equipped with GPS devices and stationary sensor systems. Various visualization methods and styles of presentation are discussed with focus on linear structure of gathered traffic data along observed routes. Visualized data is available via interactive web interface which uses modern vector graphic standard and enables presentation of as much information as possible with common, well-known traffic symbolism

Time-Dependent Route Planning for the Highways in the Czech Republic

“…2. The speed profiles used in our experiments were computed from data, which was obtained due to online traffic monitoring by viaRODOS system [8]. The experimental set of data was extracted from two months (October and November 2014) with traffic work on the highway D1.…”

AutoTuning and Adaptivity appRoach for Energy Efficient eXascale HPC Systems: The ANTAREX Approach

“…The approach will help to overcome the major shortcomings of the currently available navigation systems exploiting synergies between server-side and client-side computation capabilities. The efficient operation of such a system depends strongly on balancing data collection, big data analysis and extreme computational power [30,31].…”

Portable Telematic System as an Effective Traffic Flow Management in Workzones

“…Input values of the model were obtained from measurements performed on highway closures and also using the values for estimating the capacity of highway closures in [1] and [2]. Traffic flow model was calibrated and validated in comparison with the source data from floating vehicles [8]. Control scenarios, which were verified on the models, were created in the other stage.…”

“…After completion of the testing it was attempted to determine the total economic losses incurred due to delays in the work zone near Vyškov and show the importance of measures that lead to elimination of delays and traffic accidents. For these calculations, we used data from the system RODOS (from the system of floating car data) [8], where we compared the five-minute aggregated outputs from ASIM detectors located at road mileage 207 and 226 (traffic volume, classification) with the values of delay in individual segments of the affected site. As input values for idle time of cars, trucks and buses we used the HDM-4 methodology [7].…”
