Lately, news about electric vehicles hasn’t been so rosy. The federal government has dramatically changed its transportation priorities, and the private sector has pulled back from or delayed significant EV investments. With electrification of the transportation system looking like it may proceed more slowly, states can still take other avenues toward a more sustainable system.
Planning
Advanced models can’t replace sound judgment
The investments made by transportation agencies are often guided by increasingly sophisticated models and forecasts, which strive to account for more factors and become more accurate in predicting travel patterns. These improvements, while promising for the future, also highlight the many ways that most agencies’ existing models miss the mark. Values-based decision-making can help agencies achieve the outcomes they have set out in their long-range plans more effectively than relying on models alone.
Mobility hubs can increase access for disadvantaged groups
For DOTs looking to create a more connected and multimodal transportation network, mobility hubs are an emerging piece of infrastructure that can make changing modes and traveling across a region more convenient and environmentally friendly. But not everyone has the same ability to access and use these hubs. State DOTs looking to build mobility hubs can incorporate the needs, ideas, and feedback of disadvantaged groups to better plan, design, and build these spaces for everyone who might use them.
Moving from LOS to VMT is more complicated than it might seem
Traffic engineers across the U.S. are accustomed to measuring road performance in terms of “level of service,” or LOS. Recognizing its unintended consequences, many transportation professionals and advocates have urged the industry to replace it with something better. However, LOS has become so ingrained in many processes that there is probably no single alternative to its use.
Climate change, equity factor into recent litigation against state DOT projects
Pursuing statewide or agency climate and equity goals isn’t just preferable for state DOTs, it can also be a matter of risk management. Several lawsuits targeting major transportation infrastructure projects, most recently in Wisconsin and Oregon, have taken aim at alleged failures to consider alternatives to capacity expansion that would reduce harm to the environment or inequitable project outcomes.
Severe weather is pushing up the costs of car ownership
Ford’s Model T was a groundbreaking feat of mass production—cutting car costs by more than half over the course of a decade and spurring the massive rise in automobile use across the U.S. Those days seem far behind us, according to the latest reports. Transportation costs have risen by nearly 20% since 2022, as reported in the Wall Street Journal, and car insurance in some states could rise 50% by the end of the year.
Climate change presents an opportunity for bolder transportation policies
Individuals concerned about climate change often support sustainable transportation policies, such as reducing car use or adopting new mobility solutions. Studies from Norway highlight how varying attitudes toward these types of policies can influence their effectiveness. While some groups back most transportation initiatives—whether they involve incentives or regulations—others resist any policies they perceive as restrictive. Gaining insight into these diverse attitudes, especially among those neutral toward different strategies, can help shape effective policy.
Telecommuting most likely increases travel
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.
