ACEC’s ENGINEERING INC. — Smart Roads Ahead: A New Era in Transportation Connectivity

Monday, December 21st, 2015
Engineering Inc. - November/ December 2015

AMERICAN COUNCIL OF ENGINEERING COMPANIES
The automobile is undergoing a radical transformation. Advancements in technology, along with growing pressure to reduce congestion, trim carbon emissions and improve safety, are fueling the concept of connected cars and smart transportation systems.
How these technological advances will impact America’s roadways is a new challenge facing engineering firms. There’s growing demand to develop smart infrastructure systems that do things such as alter traffic flow dynamically. Motorists are using apps, such as Google Maps and Apple Maps, to bypass congestion and incidents, but far more advanced vehicle-to-vehicle (V2V) communication and vehicle-to-infrastructure (V2X) systems lie ahead.

Tunnel Trouble: Crumbling Infrastructure Is Putting the NYC Metro Region at Risk

Tunnel Trouble: Crumbling Infrastructure Is Putting the NYC Metro Region at Risk

The tri-state area is loaded with bridges, rail systems and roadways that are suffering from years of under-investment. But perhaps the biggest risk we face is with the rail tunnel linking New Jersey and New York. Built more than a century ago, the fraying tubes that carry NJ Transit and Amtrak trains are the biggest chokepoint in the Northeast, and the source of frequent delays for commuters. For years, the tunnels have needed extended repairs that are impossible to do while keeping trains running. The situation deteriorated when the tunnels flooded with salt water during Hurricane Sandy. Amtrak officials say the tubes might not last 20 years.

PortMiami Tunnel: The New Standard in Transportation Infrastructure

Wednesday, October 28th, 2015
Port of Miami Tunnel Project Overview

LILLY & ASSOCIATES
INTERNATIONAL TRANSPORTATION LOGISTICS
Just a few years ago, PortMiami suffered from traffic problems that rivaled downtown Manhattan. More than 16,000 cars and trucks traverse the streets surrounding the port every day, and traffic from cargo trucks makes up more than a quarter of that figure. Prior to the tunnel project, the existing bus and vehicle routes were struggling to support the massive weight of this congestion and inhibiting further growth in the region.

U.S. DOT: Using GPS For Transportation Research

These days GPS makes a transportation planner’s research effort much easier. Until now access to the data created wasn’t so easy. Watch the video to see how FHWA’s Office of Planning, Environment and Realty’s Research Program teamed with U.S. Department of Energy’s National Renewable Energy Laboratory to access secure travel data on the web.

Washington, DC: Bicycle Infrastructure and Traffic Congestion

Monday, September 14th, 2015
Figure 1: Bikeshare Trips (departures and arrivals)

RESOURCES FOR THE FUTURE
A new mechanism to reduce urban traffic congestion that is currently gaining traction for its purported cost-effectiveness, environmental-friendliness, and positive health impacts is the adoption of citywide bicycle-sharing systems. This infrastructure provides an alternative to driving for short trips and extends the existing network of public transit within a metropolitan area. Further, bicycling infrastructure augments the environmental bona fides of densely populated urban areas (Kahn, 2010). If bikeshares reduce traffic congestion, they may provide a low-cost policy lever to reduce automobile externalities in urban areas.

2015 Urban Mobility Scorecard

Tuesday, September 8th, 2015
Exhibit 1. Major Findings of the 2015 Urban Mobility Scorecard (471 U.S. Urban Areas)

TEXAS A&M TRANSPORTATION INSTITUTE
The national congestion recession is over. Urban areas of all sizes are experiencing the challenges seen in the early 2000s – population, jobs and therefore congestion are increasing. The U.S. economy has regained nearly all of the 9 million jobs lost during the recession and the total congestion problem is larger than the pre-recession levels.

Tolling in the United States

Wednesday, July 1st, 2015
HIGHWAY TRUST FUND RECEIPTS: 1970 - 2009

INTERNATIONAL BRIDGE, TUNNEL AND TURNPIKE ASSOCIATION (IBTTA)
Q: Why do we need tolls to pay for roads and crossings?
A: No matter how you slice it, federal and state fuel taxes are insufficient to support America’s highway infrastructure. Tolls provide a valuable source of revenue both to build new roads and maintain existing roads.
