Traffic index calculation caltrans
The R-Value test measures the response of a compacted sample of soil or aggregate to a vertically applied pressure under specific conditions. This test is used by Caltrans for pavement design, replacing the California the R-value of the layer below and the expected level of traffic loading, expressed as a Traffic Index. 14 Dec 2018 610-2. 613.

availability of load data. Common to both analysis techniques is the Traffic Index, which is a direct input into the thickness design equation. The Traffic Index for both methods is based on the anticipated traffic loading for a 20-year design period and determined as follows. 510.02.01 On-System Route Traffic Index. Traffic count information for city and county streets may be found at the city Traffic Engineering or Public Works Department, or the Community Development Office in the area where the street is located. Explanation of Traffic Counts (Back & Ahead Leg Diagrams) (PDF) Caltrans Traffic Counts are summarized annually into four categories:
