Since the passage of the National Maximum Speed Limit (NMSL) of 55 miles per hour (mph) in 1974 through its repeal in 1995, the federal government has mandated speed monitoring programs. The speed monitoring program was primarily intended to provide reliable data for inclusion in states’ annual certification for Federal Aid Highway Projects. The repeal of the NMSL in 1995 not only authorised states to set their own speed limits but also allowed them to develop their own speed monitoring programs. This paper develops a seven-step framework for a speed monitoring program tailored to meet the needs of individual agencies using speed monitoring data at the state level. The proposed speed monitoring plan distributes speed monitoring stations to highway classes according to three primary criteria: spatial distribution, crash distribution, and daily vehicle-miles travelled (DVMT) distribution. The proposed plan is also compared with the existing speed monitoring program. (Author/publisher)
