• Abstract:
  For highway maintenance and planning purposes, each road segment is characterized by its traffic flow such as the annual average daily traffic (AADT) and the AADT for each vehicle class, by the weight distribution of vehicles that travel on its roads such as the annual average daily equivalent single axle loadings (ESAL) and the annual average daily weight per vehicle for each vehicle class. In practice, a few road segments are monitored continuously every day of the year to produce annual characteristics of traffic flow. A sample of the remaining road segments are monitored for one or two days each year. These road segments are called the short-term monitored sites. Data collected from the short-term monitored sites are then "adjusted" (using factors based on data collected from the continuously monitored road segments) to produce estimates of annual average daily characteristics. With this general approach, each state strives to provide (or help provide) estimates of annual characteristics for each road segment within its boundaries. This report provides highlights of research reported in five working papers. Results from this project are based on a few continuously monitored sites from two states Florida and Washington, whereas data is sought from additional states.
