How Data Helps Get You There Faster

How Data Helps Get You There Faster

Traditionally, pavement inductive loop sensors are used to collect real time traffic data for passenger-freight movement in roadways. This method, however, is expensive to install and maintain. In the last decade, significant improvements have been achieved in MEMS sensors domain with respect to size, cost and accuracy. Motivated by these novel advances, we proposed a wireless MEMS sensor based passenger-freight interactions detection framework for Intelligent Transportation Systems (ITS). Our proposed solution will be significantly cost effective in comparison to traditional induction loop approach and it is scalable to cover millions miles of roadways all over the US.

Report Card for Alabama

AMERICAN SOCIETY OF CIVIL ENGINEERS (ASCE)
ALABAMA SECTION
The bad news is that Alabama’s infrastructure has some challenges that you should know about before it’s too late to keep these systems from breaking down. Infrastructure deteriorates every single day as it ages, just as our bodies do, and many of these critical systems are reaching the end of their useful life…The good news is there are solutions to all these challenges , and we can raise Alabama’s infrastructure grades. By learning more today about the conditions of the infrastructure you use every day, you too can help raise the grade.

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

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.
