Development of a Speed Monitoring Program for Indiana

摘要

From the passage of the National Maximum Speed Limit (NMSL) of 55 mph in 1974through its repeal in 1995 speed monitoring programs have been mandated by the federal government. The speed-monitoring program was primarily intended to provide reliable data to be included as a part of the State's annual certification in order to be approved for Federal Aid highway projects. The repeal of the NMSL in 1995 not only authorized states to set their own speed limits, it also allowed states to develop their own speed monitoring programs. The goal of this research is to provide the framework for a speed-monitoring program to meet the needs of agencies and organizations that use speed-monitoring data in the State of Indiana. A proposed speed monitoring plan is developed and distribution of speed monitoring stations to highway classes according to three primary criteria: spatial distribution, crash distribution, and distribution of daily vehicle miles traveled. The proposed speed-monitoring program will utilize 38 existing speed, weigh-in-motion, and automated traffic recording stations. The stations will be monitored four times a year for a 24-hour period.
