Abstract
Keywords: RADAR, GPS, data processing, statistics, road traffic
RADAR devices are commonly used for on-board or fixed point speed measurements. GPS devices, now more affordable and precise, can be also successfully used for the vehicle behaviour study. Algorithms and computer programs were designed for GPS data real-time- and post processing. This paper shows some possibilities to collect and process road traffic data using that type of devices. The presented results – as velocities, accelerations, road congestion or other traffic characteristics – are obtained by original methods, using CAD programming. The CAD software helps to easily store, process and graphically present all the input and output information. The methods described in this paper can be used to analyse and manage the traffic flows.
