Title: SOME ELECTRONIC MEASUREMENTS OF MACROSCOPIC TRAFFIC CHARACTERISTICS ON A MULTILANE FREEWAY
Accession Number: 00227929
Record Type: Component
Abstract: THE MEASUREMENT IS REPORTED OF THE COMMONLY SOUGHT CHARACTERISTICS OF MACROSCOPIC TRAFFIC FLOW BY MEANS OF AUTOMATIC SENSING EQUIPMENT USING A HIGH-SPEED DIGITAL COMPUTER FOR DATA COLLECTION AND ANALYSIS. INDEPENDENT MEASUREMENTS OF SPEED, DENSITY, FLOW, AND KINETIC ENERGY ARE OBTAINED FROM ULTRASONIC PRESENCE DETECTORS AND FROM AN OPTICAL SPEED TRAP. THE RESULTS ARE COMBINED TO PRODUCE COMPOSITE MEASUREMENTS WHERE POSSIBLE. THE ABILITY OF EACH MEASUREMENT TECHNIQUE TO PRODUCE REASONABLE VALUES IS ANALYZED BY LINEAR REGRESSION, AND THE CONFORMANCE OF THE DATA TO ACCEPTED TRAFFIC FLOW THEORIES IS DISCUSSED. FINALLY, SOME THOUGHTS ON THE APPLICATION OF THESE RESULTS ARE EXPLORED. /AUTHOR/
