The impacts of telecommuting often come up in SSTI’s work around travel demand management and climate action plans, so our team makes a point of staying on top of the latest relevant research. Although the pandemic showed us that remote work helped cut traffic considerably, especially in major job centers, the verdict is still out on whether widespread telecommuting could really help lower travel demand. A growing number of studies suggest it could have the opposite effect.
As the federal government significantly invests in vehicle charging infrastructure, states voice their concerns on effectively implementing a consistent and reliable nationwide network while addressing their local needs. Many states are committed to supporting the transition to electric vehicles, but some are looking for more flexibility with funding requirements to coincide with their existing capacity for an effective system.
More and more people are recognizing the costs associated with driving, and that driving less opens space for alternatives and makes us healthier. Now new research adds one more tick to the human health costs column: particulates from transportation cause cancer.
More studies over the years have shown us that the price and availability of parking has a strong influence on people’s travel choices. A ten-year-old study from New York, for instance, called attention to the influence of parking availability on people’s decision to drive to work. Several years later, I led a study connecting long-term parking growth to citywide increases in car commuting. Now a new study by a cohort of researchers across North America, including myself, makes that connection even clearer by drawing a direct line from residential parking ratios to household VMT.
The Infrastructure Investment and Jobs Act is a more than $850 billion historic investment in support of state and local government work to increase access and safety while redressing inequities across the country. However, a recent article by Brookings contributors Ellory Monks and Shalini Vajjhala points out that the existing structure of federal and state grant application processes may inhibit the fair allocation of the funds.
The goal of investing substantially in public transportation infrastructure and complementary transit oriented development (TOD) is to create positive outcomes for communities, including reducing carbon emissions, increasing access to jobs, and reducing reliance on personal vehicles. Two new studies highlight additional impacts of these investments; transit infrastructure leading to increased levels of physical activity and TOD residents forgoing driving for non-commute trips.
A landscape that was once dominated by taxis and then gave way to mobile ride-hailing companies like Uber and Lyft (aka transportation network companies, or TNCs), appears to be taking on a new hybrid form as some taxi companies take cues from their modern competitors and even figure out how to partner with them.
The adoption of electric vehicles is growing in the United States, with all-electric vehicle sales increasing by 85% from 2020 to 2021 and plug-in hybrid sales rising 138%. This is a welcome trend for many, but the increased popularity of EVs combined with better fuel efficiency, and a gas tax that hasn’t been raised in thirty years, is posing a major challenge to policy makers; how to make up for lost gas tax revenue, which currently pays for 29% of state highway funds and 84% at the federal level.
Since early in the highway era, road designers have tended to favor wide, rounded corners, and dedicated slip lanes that let drivers turn through an intersection without having to slow down quite as much. As many engineers and transportation advocates know, however, those wide turning radii can create issues for people trying to cross on foot. They create longer crossing distances, exposing people to traffic longer, and they increase the chance of a pedestrian crash by 50 percent or more, according to one new study.
A small but growing number of state DOTs are putting planned highway expansion projects on hold as they work to stretch their available funds and assess how to meet ambitious environmental goals. Certain environmental organizations, cities, and equity-focused advocates interested in rebuilding communities damaged by urban freeways are among those pressuring DOTs to change their long-standing practices.
