Drive Alone Commute Mode Share

Drive Alone Commute Mode Share for Arlington Residents and Arlington Workers

Description

Drive alone commute mode share is the proportion of commuters who are driving alone to commute to work. Arlington tracks the drive alone commute share both for Arlington residents and individuals who work in Arlington and compares these mode shares with those of all regional commuters.1

Why is This Measure Important?

Arlington County anticipates a 22 percent increase in population and a 38 percent increase in jobs between the years 2010 and 2040. As Arlington’s existing roadway infrastructure is already built-out, accommodating this economic growth will require a sustained shift to commute modes other than drive alone.

Current Status

The share of commuters driving alone to work has fallen since 2001 for Arlington residents, Arlington workers, and regional residents.

The proportion of Arlington residents driving alone to work has fallen faster than for Arlington workers or regional residents.

In Arlington County, 90% of residents live within ½ mile of a bus stop, and 28 percent live within a ½ mile of a train station, compared to 53% of regional residents who live within ½ mile of a bus stop and 6 percent who live within a ½ mile of a train station.

While access to commute options is greater in Arlington than the region as a whole, many factors have contributed to the decline in drive alone share for both Arlington residents and workers, including Arlington County's extensive Transportation Demand Management resources through Arlington County Commuter Services.

Endnotes

1The commute mode share for workers, residents, and regional residents includes all individuals these groups, and it is important to note that these populations overlap. Regional residents includes both Arlington residents and those who work in Arlington, as well as individuals who live and work throughout the Washington, DC region. Just 22 percent of individuals who work in Arlington also live in Arlington.
