Axle and Length Classification Factor Analysis and Effects on Annual Average Daily Traffic (AADT)
Project objectives are as follows: (1) Assemble State Departments of Transportation (DOTs) and industry experts to conduct research and statistical analysis on millions of traffic data records in order to provide guidance and understanding on the variability of how axle and length classification data affect Annual Average Daily Traffic (AADT), specifically with regard to the creation of axle factors. (2) Gain a quantitative understanding on how length classification traffic data affects the calculation of AADT. Length classification sites are more cost effective than axle classification sites from installation to maintenance. This objective will allow DOTs to fully understand the statistical significance and soundness when using this cost-effective data collection option. (3) Gain a quantitative understanding of how axle and length classification traffic data interact and affect the calculation of AADT. State DOTs that have both these types of continuous classification traffic site installations or State DOTs who are considering including the lesser expensive length classification sites to their continuous program will understand advantages and distinctions of utilizing these combined data sources. Organizational Structure is as follows: TECHNICAL COMMITTEE - State Department of Transportation Agencies Lead State - Wisconsin DOT: (1) Agency proposing the pooled fund; (2) Act as the sponsoring agency; (3) Receive invoices from the selected vendor; and (4) Assist in soliciting new pooled fund partners. Participating States: (1) Review, comment on, and recommend for approval all project proposals generated through their participation on the Technical Committee; (2) Make final decisions of the approval of any project proposal; Participating states, including the lead state, will have one vote on the Technical Committee. Selected Vendor will: (1) Prepare invoices to be sent to Wisconsin DOT for research activities; (2) Plan, coordinate, and facilitate meetings of the Technical Committee using teleconferencing and other available technologies, as well as face-to-face meetings; (3) Prepare draft proposals that include work plans and budgets to be presented to the Technical Committee for review, comment, and approval; and (4) Prepare quarterly reports to be submitted to the Technical Committee and the Wisconsin DOT.
