Warmer, wetter weather may lead to an increase in traffic injuries and fatalities unless interventions are put in place to adapt to these changing conditions.

How much are people willing to pay for self-driving cars? RFF’s Benjamin Leard discusses his work on consumer demand for autonomous vehicles and the potential implications for society of wider adoption of these new technologies.

If carefully designed, state policies can complement federal measures to help achieve a cleaner vehicle fleet and more efficient transportation system.

Urban bike sharing is gaining popularity for its purported health, environmental, and traffic congestion benefits. Evidence from Washington, DC, one of the most congested US cities, suggests that the Capital Bikeshare program reduces traffic congestion.

To reduce road congestion, Republicans propose delegating the repair, expansion, and construction of roads to private firms, to be financed by private tolls. But motorists would be better off if congestion tolls were instead set by the government.

It is no secret that the state of infrastructure in US cities is less than stellar—but what are the economic costs of the small deteriorations that citizens incur each day?

Individual municipal water systems are responsible for providing clean water for hundreds of thousands of people, yet aging pipes lead to water main breaks that not only disrupt water service, but also affect traffic—but at what cost?

To reduce traffic congestion and air pollution, many cities in developing countries have considered restricting vehicle ownership. Contrary to past research, we find that adding a car has little impact on total distance traveled or time spent traveling.

Earlier this week, Mexico City issued an air pollution alert due to levels nearly 1.5 times the acceptable limits. Four days later, the alert was still in effect, resulting in an order to remove 1.1 million cars from the capital’s streets. This follows a decision last year to relax driving restrictions in the city, a move that “put an extra 1.4 million cars a day on the streets.”
