Abstract:

One objective of statewide traffic monitoring ; programs is to accurately estimate the Annual ; Average Daily Traffic (AADT) for many roadway ; segments within the state. The majority of the ; departments of transportation (DOT) in the United ; States implement a traditional method developed by ; Drusch in 1966. According to this method, traffic ; volumes are collected continuously from automatic ; traffic recorders (ATRs) and supplemented with ; shorter duration 24, 48 or 72-hour coverage counts ; in areas where there are limited or no available ; ATRs. Once the short-term counts are recorded, ; adjustment factors including daily, weekly, monthly ; or seasonally are then used in concert with the ; short-term counts to estimate AADT. One ; criticism of this approach is the number of steps ; required which increase the overall error within the ; final AADT estimate.
