A recent study from the Netherlands found that while active travel might not affect body weight, it does have a significant positive impact on a traveler’s mental health. The results from this study suggest that while active travel does not predict BMI, the decrease in BMI levels as a result of healthy eating habits and physical exercise does result in the uptake of active travel. Conversely, an increase in BMI was associated with decreased affinity toward active travel. On the other hand, the researchers observed a strong relationship between active travel and the traveler experiencing positive emotions.

With traffic down, Oregon DOT can move more vehicles at twice the speed
With overall traffic down due to the COVID-19 pandemic, one highway in Oregon is now moving higher traffic volumes at twice the typical speed, according to an analysis by Joe Cortright at City Observatory. This might seem counterintuitive, but it perfectly illustrates the benefits of managing traffic demand, based on simple traffic engineering principles.
Oregon moves toward a safer speed-limit approach
The Oregon Transportation Commission last month approved a revised speed-limit guidance that abandons the long-standing-but-arbitrary 85th percentile rule in many cases. Instead of relying on drivers to set speeds by their behavior, the new guidance provides context-based safe speed ranges for urban and suburban roadways, ranging from 20-25 mph in urban cores to 25-35 mph in more suburban areas. The rule gives leeway for setting limits outside of those ranges. Rationales for exceptions do include observed motorist speeds, but they are based on the slower 50th percentile rather than the 85th.
The risk of premature death from transportation noise
The health risks of exposure to transportation noise may not command the same attention as those of exposure to particulate matter or motor vehicle crashes. But it turns out that prolonged exposure to noise is a serious matter, with numerous deleterious health effects—from sleep disruption and behavioral changes, to hearing loss, hypertension, and heart disease. New research focusing on Houston, Texas, attributes nearly as many premature deaths to transportation noise as to motor vehicle crashes, and shows that low-income households are at heightened risk of death from transportation noise exposure.
Effective prioritization of curbside usage: data gaps and infrastructure limitations
Owing to the rising popularity of ecommerce, expedited deliveries, ride-hailing services, and micromobility options, curb space is in demand now more than ever. Because curbside is a public property, the burden of efficiently allocating this commodity comes down to city officials. However, despite being valuable real estate, a recent study demonstrates how city staff presently do not have the data or tools to efficiently prioritize the distribution of curb space, let alone profit from it.
Canadian non-driving seniors less likely to engage in activities outside the home
A study of out-of-home participation in social and civic activities among Canadian senior drivers and non-drivers sheds light on the problems faced by both individuals and communities to keep older adults engaged and healthy. Of particular concern was the finding that non-driving seniors in rural areas and small towns had a significantly higher decline in out-of-home activities when they no longer had a driver’s license.
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.
Destination access bills introduced in U.S. House
A trio of U.S. House members along with 10 co-sponsors have introduced a pair of bills that would set destination access as a national performance measure. Both bills describe destination access, aka “accessibility,” in terms of travel times by auto, transit, walking, and biking, with consideration for traffic-stress levels on the active modes. One of the bills focuses on access to employment, while the other focuses on access to non-work destinations such as shopping and schools.
How best to get our economy and jobs back: Lessons from ARRA
The current COVID-19 pandemic has created unique transportation challenges for cities and states. This includes everything from maintaining transit with plummeting ridership to facing a needed economic recovery with major decreases in the taxes that pay for transportation maintenance and improvements. With the CARES Act passed and more stimulus and recovery funding being considered, the national experience with the ARRA funding from the last recession might hold lessons for how to jump-start the economy and job creation.
Planning for an uncertain future
Traffic forecasts and other projections are often presented as a single line on a graph or number in a chart. But we know—now more than ever—that these predictions are full of uncertainties. The Sacramento Council of Governments (SACOG), for a new study in JAPA, puts hard numbers to some of those uncertainties in order to plan better for them.
