SAFETY BENEFITS OF SIGNAL COORDINATION

This study has attempted to cut through all of the potential pitfalls of a safety benefits study. The first step was to identify corridors that had signal coordination systems implemented within the last 5 years. Usually, agencies keep accident records for at least 5 - 7 years, so this was taken as a maximum limit for the data request. Next, questionnaires were sent to the traffic departments of numerous transportation agencies in the northeast, asking them to identify their corridors with new coordination systems, and to supply data on the system such as length, limits, number of signals, data implemented, type of coordination system used, and controller types. These agencies included State DOT's, plus County DOT's and City Transportation Departments in major metropolitan areas in New York, Pennsylvania, Ohio, Maryland, Massachusetts and Connecticut. These locations allowed the study to have a qualified traffic engineer observe corridor operations.
