EXAMPLE OF OD TRAFFIC VOLUME SURVEY BY A HELICOPTER AND VERIFICATION OF THE APPLICABILITY OF STATIC ESTIMATED OD TRAFFIC VOLUME WITH RESPECT TO THE DYNAMIC ANALYSIS

Abstract

It is necessary to understand the traffic demand (OD traffic volume) at the time of congestion in the urban area in order to do the congestion easing and the transportation demand management. So far, in order to grasp the traffic demand, the observation of license plate primarily has been used, but the observer's safety management was a problem. In this study, the OD traffic volume by the aerial video filming of the helicopter that did not need the investigators in the investigation site was observed, and the feature of this survey method was arranged.
Moreover, a lot of estimation methods of the OD traffic volume at the time of congestion have been researched so far. In this study, after the statical estimation of the OD traffic volume at the time of congestion by the existing OD traffic volume estimation technique, the applicability to dynamic analysis of a statical method of OD traffic volume estimation is verified with using the traffic micro simulation that is used in various dynamic analysis recently.
