The Transportation Agency’s regional traffic counts program monitors the level of service on regional roadways. Our agency’s primary goal for collecting new regional traffic counts is to provide fresh data for the Association of Monterey Bay Area Government’s regional travel demand model. Count locations are on the county’s regional road and highway network, in addition to locations requested annually by Caltrans as part of its Highway Performance Monitoring System.
Traffic data is collected twice a year, once in March or April (off-peak) and again in August or September (peak). Traffic counts are conducted over a two-day 24-hour vehicle count period, either on a Tuesday/Wednesday or Wednesday/Thursday. The Average Daily Traffic (ADT) is the measure we use. The 24-hour counts for the two-day period are averaged together to arrive at the ADT.
