Sustainability Goals

Workers are able to conveniently reach their jobs via a variety of low-carbon transportation choices, including public transit, walking, biking, and ride-sharing.

Indicator Overview

San Mateo County’s central location between two major employment hubs in San Francisco and Santa Clara Counties and a lack of affordable housing on the peninsula means that the county has high levels of cross-county commuting. On a given work day, over 500,000 workers commute into, out of, and within San Mateo County, placing tremendous stress on our aging transportation infrastructure. The resulting traffic congestion lengthens commute times, reduces worker productivity, and increases air pollution.

Vehicle Miles Traveled

Vehicle Miles Traveled (VMT) is the total number of miles driven by all vehicles in a given time period and geographical area. Factors influencing VMT include population, the state of the economy, personal income, number of registered vehicles per person, and fuel costs. Vehicle Fuel Consumption (VFC) is the total gasoline and diesel fuel usage on all public roads in a given time period, and it is influenced by VMT and fuel efficiency of vehicles.
