Abstract:The results of the project to collect freeway traffic data for use in developing and verifying incident detection algorithms are presented in three volumes. This volume gives a description of the 80 data sets collected from the closely spaced detectors on a section of the San Diego Freeway. This freeway is part of the 42-mile freeway loop that had magnetic detectors with an average spacing of one-half mile. Included are a description of the freeway system used, classification of the data sets, description of 80 data sets, an overview of an analysis program that will process the data sets, weather conditions and a description of an incident. Other volumes in this report include: Vol. 1, RD-76-175, Traffic Data Sets from Widely Spaced Detectors; and, Vol. 3, RD-76-177, FORTRAN Program Documentation for Analyzing Individual Data Sets.
