U.S. Transportation Construction Market Forecast 2013 - This report forecasts the U.S.
transportation construction infrastructure market will show modest growth in 2013, increasing three
percent from $126.5 billion to $130.3 billion. Growth is expected in highway and street pavements,
private work for driveways and parking lots, airport terminal and runway work, railroads, and port
and waterway construction.
- Understanding Road
Usage Patterns in Urban Areas - This report tracks travel using anonymous cellphone data rather
than survey data or information obtained from U.S. Census Bureau travel diaries. It demonstrates that
canceling or delaying the trips of 1 percent of all drivers across a road network would reduce delays
caused by congestion by only about 3 percent, but canceling the trips of 1 percent of drivers from
carefully selected neighborhoods would reduce the extra travel time for all other drivers in a
metropolitan area by as much as 18 percent.
- Passenger Rail Security:
Consistent Incident Reporting and Analysis Needed to Achieve Program Objectives - This report

passenger rail agencies to report all potential threats and significant security concerns to TSA
and (2) TSA has analyzed passenger rail security incident information to identify security trends.
