Airborne Remote Sensing: Redefining a Paradigm of Traffic Flow Monitoring

D. Grejner-Brzezinska, C. Toth, E. Paska

Abstract:	The major focus of this paper is the feasibility of airborne multisensor remote sensing systems to support traffic flow parameter estimation. The traffic flow parameters that are presented are (1) intersection traffic volumes, (2) intersection movement as a function of the traffic light patterns, and (3) the intersection turning movements. The sensor suite that is considered here is an airborne 4K by 4K CCD digital camera supported by a GPS/INS integrated system providing direct georeferencing of the imaging sensor. The experimental test results based on a helicopter-based data set collected over a transportation corridor in Tucson, Arizona in May 2002 are presented. The feasibility of using airborne imagery for traffic flow estimation is demonstrated, and the expected future trends are discussed.
