The results of the project to collect freeway traffic data for use in developing and verifying incident detection algorithms are presented in five 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 has magnetic detectors with an average spacing of one-half mile.
