The long-term efficiency and effectiveness of the U.S. freight transportation system is threatened by bottlenecks, inefficient use of some parts of the infrastructure components, vulnerability to disruptions, and crucial environmental and energy concerns.
Policymakers need to address equity concerns early when implementing congestion pricing to improve traffic flow, as each situation is unique. Because these policies impose a cost on something that previously was not priced, it can harm lower-income drivers who will be forced to pay additional costs or be "priced off" the roads.
President Obama's infrastructure plan doesn't yet carry a price tag. We only know that it will be big.... The trick is how it will be done. It will not be enough to simply rebuild and repair critical infrastructure systems. We need to reinvent the systems themselves, writes Martin Wachs.
The economic slowdown threatens to put a crimp in ambitious efforts to balance preservation, transportation improvements and development in western Riverside County. It doesn't have to. Actually, it presents an opportunity, writes Lloyd Dixon.
Western Riverside County's Multiple Species Habitat Conservation Plan -- a sweeping effort to protect endangered and threatened species while accelerating the approval of transportation improvements -- has made significant progress, but needs modifying to reach its goals in Southern California's changing economy.
A comprehensive look at Los Angeles traffic debunks common myths about the metropolitan region's traffic patterns and details the reasons why congestion is so bad -- and why it will get worse in the coming years without significant policy changes.
This research brief identifies key factors determining L.A. transportation policy needs and makes 13 recommendations that together could reduce congestion -- arguably the worst in the country -- substantially within five years.
Building on analyses that RAND conducted between 2002 and 2004, this presentation explores the options for strengthening the physical infrastructure of a potential future independent Palestinian state.
A comprehensive look at Los Angeles traffic debunks common myths about the metropolitan region's traffic patterns and details the reasons why congestion is so bad — and why it will get worse in the coming years without significant policy changes.
The volume of freight transported in the United States is expected to double over the next 30 years. Greater use of rail freight could allow the supply chain to accommodate this increase while minimizing highway congestion and reducing fuel consumption.
