As sea levels rise and extreme weather events become more common, evacuation routes in coastal areas will become more important. Transportation engineers need to be more proactive as they try to anticipate damage to pavement, bridges, and culverts.
As China strives to sustain its upward economic trajectory, it must also address its domestic problems—such as air pollution and the challenges presented by its aging population—if its people are to share fully in the rewards of economic development and expansion.
Using vehicle miles traveled as a means of distributing the cost of maintaining America's roads and bridges may not be the only answer. But it represents the kind of innovative thinking that is necessary when this sector of the American transportation infrastructure is desperately in need of a fix.
Oregon is rolling out the nation's first large-scale pilot to examine switching to a mileage fee instead of the gas tax. The trial is a welcome next step toward understanding how mileage fees can be deployed.
In what ways will the mandate, role, funding, and operations of state departments of transportation be affected by changes in energy supply and demand in the next 30 to 50 years? Different supply-and-demand scenarios will require robust decision-making techniques.
Although countries with high levels of economic development generally have more personal automobile travel than less-affluent nations, income is not the only factor that determines a nation's demand for cars.
The level of automobility, or travel in personal vehicles, varies among countries. By determining the factors besides economic development that have affected automobility in developed countries, researchers can predict how automobility might evolve in developing countries.
Automobility -- travel in personal vehicles -- varies between countries. This brief summarizes a study of the factors besides economic development that affect automobility and how automobility might evolve in developing countries.
In this June 2014 Congressional Briefing, Liisa Ecola discusses growing shortfalls in federal and state funding for surface transportation programs, and the potential of mileage fees (rather than fuel taxes) to reduce those shortfalls while also reducing traffic congestion, harmful emissions, and excessive road wear.
The first HOT lanes in L.A. have improved traffic flow and travel time reliability, are fair to users of the facilities, have improved transit service and have generated revenue needed to fund those improvements from voluntary toll payments.
The promise of autonomous vehicles is finally near to being realized and the substantial benefits to society in terms of safety, mobility, and fuel economy cannot be ignored. It is not too early for policy makers to begin to think about the challenges that lie ahead.
