Annual average daily traffic (AADT) is a measure used primarily in transportation planning, transportation engineering and retail location selection. Traditionally, it is the total volume of vehicle traffic of a highway or road for a year divided by 365 days.
In transportation engineering, the K factor is defined as the proportion of annual average daily traffic occurring in an hour. [1] This factor is used for designing and analyzing the flow of traffic on highways. K factors must be calculated at a continuous count station, usually an "automatic traffic recorder", for a year before being determined.
Interstate 64, east of Interstate 170 in St. Louis County saw 163,000 average daily traffic, while Interstate 670 through downtown Kansas City had 104,000 average daily traffic.
Traffic counts provide the source data used to calculate the Annual Average Daily Traffic (AADT), which is the common indicator used to represent traffic volume. Traffic counts are useful for comparing two or more roads, and can also be used alongside other methods to find out where the central business district ( CBD ) of a settlement is located.
The segment had an annual average daily traffic (AADT) of 61,500. The AADT is the total volume of traffic on a road in a year, divided by 365 days. Motorists drive on I-75 above the University ...
SR 522 is maintained by the Washington State Department of Transportation (WSDOT), which conducts an annual survey on the state's highways to measure traffic volume in terms of annual average daily traffic. In 2016, WSDOT calculated that 96,000 vehicles used SR 522 at its interchange with I-405 and 12,000 vehicles used it at its eastern ...
The bridge opened to traffic on January 15, 1963, the same day that the Cross-Bronx Expressway was completed. For 2011, the New York City Department of Transportation , which operates and maintains the bridge, reported an average daily traffic (ADT) volume in both directions of 182,174, having reached a peak ADT of 192,848 in 1990.
Taking annual data for average daily traffic (ADT) and design-hour-traffic-to-capacity (DTC) ratios during the 21 years 1976–1996, they found the growth rates between the two types of segments to be “statistically and practically indistinguishable, suggesting that the capacity expansions, in and of themselves, had a negligible effect on ...
