IMPROVED DATA SCREENING TECHNIQUES FOR FREEWAY TRAFFIC MANAGEMENT SYSTEMS

摘要: Proper functioning of computer-based freeway traffic control algorithms depends on good data being received from roadway detectors. At present, only elementary screening procedures for these are in use most management systems. There has recently been some work to improve such procedures. That extended, and several new approaches proposed. The first approach develops a theoretical upper bound part the flow-occupancy is useful single-detector other have developed paired-loop systems involve comparisons loop as well development boundaries defining acceptable combinations speed, flow, occupancy data.
