Commute Time

How long is it taking us to travel to work?

Commute Time

Definition: 
Commute time refers to the average number of minutes a commuter spends traveling to work on a typical day.

Except for individuals who work at home, over 3.7 million Bay Area workers must find a way to travel to their jobs each workday. Their choice of transportation mode, departure time, trip origin and destination all play key roles in determining door-to-door travel time. The collective result of these daily decisions is reflected in the average commute time for the region – a figure which has crept up from 24 minutes in 1980 to around 31 minutes today. While this is in the same ballpark as many other U.S. metropolitan areas, the Bay Area actually has slightly shorter commute times than many of its peers – a fact that may surprise traffic-weary residents.

Regional Performance
Commute times continued to tick upwards in 2015, hitting a record high of over 31 minutes.

Across all modes, the average Bay Area commute takes longer than ever before and now lasts over 31 minutes door-to-door. Increasing congestion and longer-distance commutes to job centers in San Francisco and Silicon Valley have contributed to this trend. Importantly, modal choice affects commute duration. Commuters choosing to drive alone spend 28 minutes getting to work, while those choosing public transit log an average commute time nearly twice as long at 51 minutes.

The longer transit commute times are not surprising considering nearly two-thirds of transit commuters work in San Francisco. Given congestion in San Francisco and its related impacts on Muni, plus long-distance commutes on BART, Caltrain and express buses from other counties, it is difficult for these commuters to get to work in 30 minutes or less. This results in above-average travel times for public transit users.

Historical Trend for Commute Time - Bay Area

Local Focus
Commute times are growing fastest for drivers living in Contra Costa County and for transit riders in San Francisco and Alameda counties.

In 2015, commute times for solo drivers in Contra Costa County increased more than anywhere else in the Bay Area. In particular, workers living in Antioch, Pittsburg and Hercules spent the most time driving alone to work. These cities in eastern Contra Costa are impacted by a regional jobs-housing imbalance where they act as bedroom communities for distant job centers. Transit riders have not been immune to rising commute times either; residents of San Francisco and Alameda counties saw the greatest increase in transit commute times in 2015.

With commute times averaging less than 25 minutes, residents of Napa and Sonoma County have the fastest commutes in the Bay Area; cities and towns such as Calistoga, Yountville, Napa and Santa Rosa have especially speedy commutes. These cities are joined by a number of jobs-rich communities in Silicon Valley such as Menlo Park and Mountain View, where residents spend under 23 minutes getting to work each morning. Notably, while Silicon Valley residents have relatively quick commutes, workers at Silicon Valley companies have relatively longer commutes as many must drive long distances on increasingly congested corridors to reach job centers.

National Context
The Bay Area has fallen in rank for quickest commutes, but the region’s residents still have average commute times compared to other major metro areas.

The nation’s major metros all have similar commute times, ranging from 28 to 36 minutes. In 2010, the Bay Area ranked 2nd for fastest commutes, but since then the region has seen the largest increase in commute time among major metros. Still, commute times in all peer metros have worsened and the Bay Area now falls in the middle of the pack. As of 2015, the region had the fifth-quickest travel times for commuters taking public transit, with times similar to Los Angeles and Chicago. For auto commutes, the Bay Area ranked fourth-quickest, with times similar to Miami and Philadelphia. This relatively good performance may be unexpected considering those metros have less traffic congestion compared to the Bay Area. This reflects the short distance between home and work for many Bay Area commuters who drive, particularly residents of the Peninsula and around Santa Rosa.

Dallas and Miami have the quickest commute times, while commuters in New York and Washington spend the most time getting to work. In New York, the relatively long commute time is due to the large share of transit users who travel on average over 52 minutes to work each day. In Washington, on the other hand, transit commutes are relatively quick while drivers have longer commutes.

Methodology Notes: 

For the decennial Census datasets, breakdown of commute times was unavailable by mode; only overall data could be provided on a historical basis. For the American Community Survey datasets, 1-year rolling average data was used for all metros, region, and county geographic levels, while 5-year rolling average data was used for cities and tracts. This is due to the fact that more localized data is not included in the 1-year dataset across all Bay Area cities. Similarly, modal data is not available for every Bay Area city or census tract, even when the 5-year data is used for those localized geographies. Regional commute times were calculated by summing aggregate county travel times and dividing by the relevant population; similarly, modal commute times were calculated using aggregate times and dividing by the number of communities choosing that mode for the given geography. Census tract data is not available for tracts with insufficient numbers of residents. The metropolitan area comparison was performed for the nine-county San Francisco Bay Area in addition to the primary MSAs for the nine other major metropolitan areas.
