This is a point GIS dataset representing Traffic Volumes (Annual Average Daily Traffic (AADT)) on the California Department of Transportation (Caltrans) state highway network.
This traffic volumes feature class containing Traffic Volumes (also known as Traffic Counts) on California state highway network created from AADT excel spreadsheet file maintained by Caltrans, Division of Traffic Operations. Annual average daily traffic is the total volume for the year divided by 365 days. The traffic count year is from October 1st through September 30th. Very few locations in California are actually counted continuously. Traffic Counting is generally performed by electronic counting instruments moved from location throughout the State in a program of continuous traffic count sampling. The resulting counts are adjusted to an estimate of annual average daily traffic by compensating for seasonal influence, weekly variation and other variables which may be present. Annual ADT is necessary for presenting a statewide picture of traffic flow, evaluating traffic trends, computing accident rates, planning and designing highways and other purposes. |
