We’ve written before about the impact of telecommuting on travel demand. Contrary to some common assumptions, it often results in longer non-work trips or broader changes in travel behavior. As transportation agencies consider telecommuting as a viable strategy to cut travel—especially since the pandemic—a new comprehensive review presents mixed results.

A transportation paradigm shift that we need is moving too slowly
Our transportation system in the U.S. is built and maintained largely on basic principles that are now a century in the making. The first principle: cities and metropolitan areas will continue growing outward. Second, almost everybody will drive. And third, by adding road capacity, we can prevent the system from breaking down. As a result, commute times have risen by more than 20% over the last 50 years and only the pandemic has offered any relief from traffic congestion. A new study now offers a fresh perspective on the current state of practice and some critical challenges to moving toward accessibility as an industry.
There isn’t a one-size-fits-all strategy to reduce car usage
Reducing the amount we drive is critical for cutting emissions while also improving health, safety, and transportation system performance. This effort requires both changes in the built environment and individual travel behaviors. The strategies for doing so typically fall into two categories: soft strategies, which focus on incentives and changing attitudes, and hard strategies, which involve infrastructure improvements and new regulations.
Black households pay more per vehicle regardless of income
People of color already face disproportionate health risks, pedestrian deaths, and discrimination directly related to our car-dependent infrastructure. A new study finds the cost of owning and maintaining a vehicle is also grossly inequitable.
More connected street networks are more resilient
As we have seen recently with the bridge and interstate collapses in Baltimore and Pennsylvania, disruptions to our street network severely impact travel. Natural disasters, like earthquakes and floods and targeted disasters, terrorist attacks, disrupt travel patterns, raising questions about why some cities are more vulnerable to these disasters than others. Especially in urban areas, when a central street is removed from the equation, people and goods still need to move to and from destinations. A new study looks at urban areas worldwide to determine what street network characteristics make them more resilient and vulnerable before and after disasters. Areas with disconnected street design like North America and Oceania are among the most vulnerable.
Pedestrian deaths spike right after sunset
As pedestrian deaths continue to rise, it has become clear that most of these deaths happen at night. But a new study finds that the half hour after sunset is the most dangerous in the United States. This worrisome trend is exacerbated by the high-speed, multilane roads that predominate in the U.S. The solutions, in addition to improved visibility, are the same at night as they are during the day: policy, design, and behavior changes that encourage safer, slower driving.
Focusing on EV charging along corridors exacerbates equity issues
Federal initiatives to fund electric vehicle infrastructure, like the NEVI program, encourage EV chargers along highway corridors, and also promote equitable distribution of the infrastructure. According to a new study, however, these two goals may be at odds. Evidence suggests the corridor-based approach is not leading to particularly equitable outcomes.
Speed cameras lower speeds and prevent crashes, new research confirms
The Safe System approach to preventing traffic deaths and serious injuries requires us to rethink every aspect of our transportation system, from road and vehicle design to our pervasive car culture. Many communities have found that automated traffic enforcement is one valuable step along the way. As more of these systems are deployed, researchers continue building knowledge about how they work and where they are most effective.
People walking are often blamed for crashes when roads are designed for driving
A pedestrian’s location at the time of a crash often determines who (whether driver and pedestrian) is found at fault, says a new study. Even with a lack of pedestrian infrastructure nearby, pedestrians who cross high-speed arterial roads with bus stops are more likely to be blamed.
Workers offset their commute travel when working from home
The massive shift to remote work during the pandemic altered the way many offices operate and increased interest in the potential for widespread telecommuting to help reduce traffic, transportation emissions, and other harmful impacts. We have reported several studies, however, that suggest remote work simply lets people drive at different times of day and for purposes other than commuting. A new study backs that finding.
