THE POTENTIAL OF 16 MM AND 35 MM TIME LAPSE PHOTOGRAPHY TAKEN FROM A HELICOPTER FOR TRAFFIC STUDIES AT COMPLEX INTERSECTIONS

Many attempts have been made to use various types of photography for traffic studies. The problems most frequently encountered are the expense involved in obtaining the photography and the time consuming and, hence, expensive operation of collecting the required data from the photography. This paper discusses the problems associated with various types of photography and describes a study which has been carried out to evaluate the potential of 16 mm and 35 mm time lapse photography taken from a helicopter. The accuracy of two dimensional co-ordinate transformation systems for collecting the required data from the photography is also described. Finally, recommendations are made regarding the most suitable type of photography and the most convenient and accurate transformation system to use when it is required to analyse the traffic flow data at complex urban and suburban intersections. /Author/TRRL/
