Critical Issues in Transportation

Tuesday, February 11th, 2014
The freight transportation system must adapt to a projected 80 percent growth in gross domestic product in the next 25 years.

TRANSPORTATION RESEARCH BOARD
The United States depends on transportation to compete globally and to help revive a sluggish domestic economy. Individuals depend on transportation not only to get to work but to shop, socialize, and access health care, among other goals (1). For all of its benefits to the nation and individuals, however, transportation imposes large costs—lost time in traffic congestion, deaths and injuries from crashes, demand for imported petroleum, and the release of greenhouse gas emissions and other forms of pollution.

TRANSPORTATION RESEARCH BOARD
Over the years, surface transportation in the United States has seen numerous major improvements and policy innovations informed by research: safer and more fuel-efficient automobiles; more durable and economical pavement designs; real-time tracking of cargo shipments; and a resurgence of freight rail following deregulation of the railroad industry, to cite but a few examples. Leaders within the transportation community have questioned, however, whether the current U.S. approach to surface transportation research will lead to the innovations in transportation services and policies needed to support national goals for economic development, safety, mobility, competitiveness, and sustainability in the 21st century.

Dear Friends,

 

It is encouraging to finally see clear signs of federal action to support a comprehensive US infrastructure investment plan.

 

Now more than ever, our advocacy is needed to keep stakeholders informed and connected, and to hold politicians to their promises to finally fix our nation’s ailing infrastructure.

 

We have already engaged nearly 280,000 users, and hoping to add many more as interest continues to grow.
