The I-880 field Experiment : Analysis of the Incident Data

This paper reports on the I-880 field experiment in which field data on incidents were collected through observations of probe vehicle drivers before and after the implementation of freeway service patrols (FSP) over a freeway section.  The paper describes the incident patterns and identifies the major factors affecting incident frequency and duration. FSP significantly reduced the response times but did not have a significant effect on the durations of all incidents.
