We know that employer-provided free parking tends to increase auto-commute trips and that employer-provided transit passes tend to reduce auto-commute trips. Research is less clear about the effect on vehicle-miles traveled, however, in part because we don’t know whether or how such employment practices might affect non-work travel. A new paper using travel survey data from the Seattle area, sheds new light on the VMT question.

Researchers look at the transportation future as the country reopens
As the economy recovers from COVID-19, how can we emerge with a better, stronger, and more resilient transportation system? Three recent reports analyzing the impact of the pandemic on transportation and personal attitudes toward transportation may offer some clues.
Teleworking’s hidden environmental costs
Because of the COVID-19 pandemic and subsequent shelter-in-place orders, more Americans are teleworking. This has drastically reduced VMT and air emissions. Policymakers may be tempted to try to encourage teleworking post-COVID-19 in order to keep the traffic down and the air clean. But as we’ve reported before, telework is probably not a great strategy for emissions reduction, due to several rebound effects. Teleworkers tend to live farther from job centers, in lower-density environments, leading to longer, more auto-dependent commutes when they do go into the office, as well as higher levels of non-work VMT.
California highway projects face review for induced travel
The implications of California’s SB 743 (2013), which is widely if somewhat imprecisely known as the “move away from level-of-service to vehicle-miles-traveled bill,” became clearer last week, as Caltrans issued guidance on which transportation projects will require evaluation for VMT effects.
Commuters won’t drive far to access park-and-ride
People using park-and-ride stations don’t seem to mind a longer overall commute, according to new research, as long as the station is close to home. In other words, it’s probably better to think of park-and-ride lots more like local feeders than as regional access points.
Sweden and Virginia: Messaging and variable tolls can influence mode choice
Two recent studies demonstrate two approaches to reducing driving. A Swedish study looked at what types of messages influence the choice to drive, while a report from Virginia shows that tolls on the I-66 corridor outside Washington have made a difference in both mode choice and when drivers travel.
Webinar recap: Parking reform for 21st century communities
Parking reform is a growing priority for cities and towns across the U.S. This has important implications for transportation professionals, outlined in a recent webinar from SSTI, the Form-Based Code Institute, and Smart Growth America.
Does Uber impact bike-share usage? Evidence from a natural experiment in Budapest
Significant research has gone into understanding the relationships between different urban transportation options and whether they support or compete with each other. It seems reasonable to think ride-hailing services like Uber might compete with bike sharing in urban areas, but findings from a recent study in Budapest suggest the opposite.
Impact of “new age” shopping behavior on VMT and the environment
There have been a number of studies studying the relationship between in-store and online shopping behavior and its impact on retail-related travel. A broadly accepted idea is that online shopping, in more ways than one, is substituting for in-store shopping and can thereby reduce shopping related travel. However, major demographic and economic factors affect shopping behavior, and expedited delivery options may reduce the potential of e-commerce to reduce VMT and greenhouse gas emissions.
Short commutes and multimodal access motivate housing choices
In choosing where to live, people strive for a combination of short driving commutes and good transit access, according to a new study spanning three large regions: Atlanta, Seattle, and Detroit. Walkable neighborhoods are also a plus, depending on the region.
