This report describes the outline and the results of a traffic survey on a 800 meter section of the Hanshin Expressway making use of areial photographs from a helicopter hovering at an altitude of about 800 meter. The objectives of the study are to record the traffic flow conditions at the time of congestion and to find out the cause of the congestion. The traffic in the study section was photographed by two 35mm still camera evry five second for one hour. All the vehicles recorded in the south bound traffic flow were numbered and traced in order to depict the trajectories in the time and space diagram. The speed and density contour diagrams are depicted making use of the theory of three dimensional representation of traffic flow. The cause and conditions of the traffic congestion are investigated with these diagrams.
