Local governments often rely on traffic impact analyses to review and approve projects, charge impact fees, and ask developers to go above and beyond the basic requirements. These traffic studies, however, are often based on “junk science,” and may not hold up in courts much longer, according to a new Viewpoint article published in the Journal of the American Planning Association.

A new playbook is emerging for managing local travel demand
Over time, transportation demand management has shifted from mainly reducing single occupancy commute trips to something more encompassing, a larger shift toward active and shared transportation for all types of trips made by all types of people.
“Dear diary, I took the bus today!” – Cost-efficient travel behavior influencers
“Soft” transportation policy measures can influence a significant reduction in personal car use, according to a new research. Six psychological variables that can affect travel behavior: attitudes; emotions; habits; social, cultural, and moral norms; knowledge and awareness ; and capability and self-efficacy. The results show that interventions that focus on social, cultural, and moral norms have the most significant effect on travel behavior.
Post-COVID travel patterns—a survey by the MassINC Polling Group
In a recent public opinion survey conducted by the MassINC Polling Group, Massachusetts residents expected to travel less in the future due to COVID-19’s impact. However, many residents expect to increase their trips by car and decrease trips by transit. A majority of residents polled are open to the idea of drastic changes to the transportation system.
“Spillover” effects reinforce VMT effects from transit and parking subsidies
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.
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.
Exploring the relationship between transit supply and parking demand
In a recent study, researchers from Australia look closely at the relationship between parking demand and proximity and quality of service supply of public transit. When other socioeconomic factors were considered, the quality of transit service became much more important than proximity alone in determining parking demand. This will be helpful in the ongoing discussion about where and how to reduce or eliminate required parking as part of development.
TDM best practice: Shout out to Greater Richmond Transit Company
In an era of falling transit ridership and utopian sustainability goals, Richmond, Virginia, seems to have hit the nail on the head. With the introduction of a bus rapid transit line and an overall bus system redesign, the Greater Richmond Transit Company has increased transit ridership in the region by 17 percent. GRTC’s distinctive carpooling and vanpooling system has grown extensively in the past decade. A recent article by Mobility Lab explains in detail the reasons and strengths behind GRTC’s continued success.
