Freeway incident and non-incident data have been collected from the San Diego, Santa Monica, and Harbor Freeways in Los Angeles, California and stored on magnetic computer tapes. The data was collected from vehicle presence sensors imbedded in the freeways which are polled by a computer 15 times per second. So that the data may be used in a variety of different applications, the time actuations of the individual wheels crossing the sensors are recorded on the tapes. Specific information on how the data is stored on nine magnetic tapes, identifying 33 specific data sets and a Fortran Analysis Program may be found in FHWA Report FHWA-RD-78-130.
