Residential neighborhoods throughout the United States seek to maintain a quality of life where residents can live free of traffic factors adversely affecting their safety. Many communities have adopted a Neighborhood Traffic Management Program (NTMP) to address concerns over cut-through traffic, speeding, and safety. The City of Centennial, Colorado, incorporated in 2001, is a young city and has its own NTMP. Four traffic mitigation projects have been implemented. The objective of this research is to conduct a before and after comparison study of each Centennial NTMP project, to review the NTMP policies of American cities with similar suburban characteristics to Centennial, and to identify and recommend efficiency improvements to the Centennial NTMP policy. The study was conducted by organizing all of the original NTMP data beginning with the first project implemented in Centennial. This was the before-data. The after-data were collected by replicating the data collection process, which included vehicle speeds, average daily traffic counts, and crash history. Speed and traffic volume data were collected with tube counters. Crash data are supplied by the Arapahoe County Sheriff’s Office and are stored in Centennial’s crash database. The data were analyzed using the Intersection Magic software. The NTMP policies from the other cities were obtained through their respective public works departments and city websites. This report presents the results of the effectiveness of the Centennial NTMP program goals, objectives, policies, and tools. The findings indicate that the Centennial NTMP needs a refocus to educate its citizens on the results of projects that have been implemented and are showing positive results. Additionally, some modifications to the existing policy, based on reviews of similar NTMPs, would improve the efficiency.
