TOWN TRAFFIC ANALYSIS BASED ON AIR PHOTOGRAPHS

ANALIZA GRADSKOG PROMETA IZ PODATAKA AEROSNIMAKA

The article describes the process of obtaining data from air photographs for town traffic analysis. Some technical information on photogrammetry, used in traffic analysis, is given. The processing of air photographs is adapted to the photogrammetric equipment used in Yugoslavia. Restitution on stereo instruments and co-ordinatograph when using photomap is described. Photogrammetry must be done in such a way that automatic data processing is possible. The final results depend on the degree of software development. Highly sophisticated software makes it possible to present the position of every vehicle or any traffic user, linked by time and space coordinates, in numerical or graphic terms. The air photographs taken in a series and on the same day yield better results than traffic counts either for the whole town area or for only a part of it. Comparing the photogrammetric results obtained on different occasions, over a longer period of time, gives the opportunity for wider analysis of traffic development. /TRRL/
