Abstract:The objective of this project was to review the Montana Department of Transportation’s (MDT’s) permanent Weigh-inMotion (WIM) and Automated Traffic Recorder (ATR) data collection programs to ensure they are efficiently providing the best possible traffic information to meet data user needs. Primary project tasks included a) review of the state-of-thepractice, from the hardware being used to the operating procedures being employed, b) compilation of a comprehensive description of MDT’s current traffic data collection program with a focus on WIM/ATR data, from field data collection to data dissemination, c) survey of traffic data users to determine if their needs are being met, d) review of current traffic factor groups, including alternatives to these groups, and e) development of a methodology to prioritize new WIM/ATR deployments. MDT currently has 106 permanent count sites statewide (42 WIM and 64 ATR sites), and 5,800 short-term count locations. The data collected are processed to generate multiple reports and maps that are available on the internet. Overall, MDT’s WIM/ATR program was determined to be efficiently and effectively meeting traffic data needs. MDT’s traffic data collection and analysis effort was found to be consistent in size/extent with that of similar states, and traffic data users were found to be very satisfied with the data being provided. As MDT’s data collection efforts continue to move forward, recommendations were made to further increase their efficacy.
