The report describes the data collection methods for a survey conducted in the St. Louis regional area. It involved only those vehicles having a gross vehicle weight rating greater than 10,000 pounds. Seventy vehicles were selected for observation. Sixty-five of these vehicles were trucks and five were buses. The chase vehicle method of collecting vehicle operational data utilizes a vehicle equipped to monitor and record its own speed and time while following ('chasing') a subject vehicle. The following information was recorded during each chase event: Day of the year, time of the day, truck I.D. number, area type (urban, non-urban), vehicle speed, manifold vacuum, road types, traffic conditions, weather type, driver-navigator I.D., catch-up mode indicator, and type of scheduled stop.
Interagency agreement no. IAG-D5-0731. Performed under contract DOT-FHWA-11-8563, with the Federal Highway Administration.
