Self-driving cars are quickly moving from prototype to everyday reality. During this transition, the question that is first and foremost on the mind of the public and policy makers is whether or not self-driving cars are more prone to crashes. This would seem to be an easy question to answer: simply compare current published crash rates with the data on self-driving cars. A deeper look at the available data and collection methodologies, however, reveals that such a simple comparison is problematic.

Wednesday, December 30th, 2015Traditionally, 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.

Monday, December 21st, 2015AMERICAN 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.
Transportation: The Path to Florida’s Future

Monday, December 14th, 2015TRANSPORTATION RESEARCH BOARD
Information and communication technologies, combined with smartphone applications and location data from global positioning systems, are making feasible transportation services that have long been imagined but never realized on a large scale. These innovations include carsharing; bikesharing; microtransit services; and, most notably, transportation network companies (TNCs) such as Uber and Lyft.
Broadband Adoption Rates and Gaps in U.S. Metropolitan Areas
Thursday, December 10th, 2015BROOKINGS INSTITUTION
METROPOLITAN POLICY PROGRAM
There is no question that the Internet is a huge boon to the economy and society, but maximizing its potential is only possible if all individuals are online. As a result, it is critical that policymakers closely track broadband adoption rates: the share of households with a DSL, cable, fiber optic, mobile broadband, satellite, or fixed wireless subscription.
Polisdigitocracy: Digital Technology, Citizen Engagement and Climate Action
Friday, November 20th, 2015Information Technology And Physical Mobility
Tuesday, November 17th, 2015INSTITUTE FOR MOBILITY RESEARCH
This study was designed to investigate the impacts on personal mobility that are attributable to people incorporating ICT into their lifestyles. We recognised the need for a holistic approach, drawing on the respective strengths of both qualitative and quantitative methods. We also recognised the need to take into account various contextual factors, such as the affluence of societies, the availability and quality of transport and ICT infrastructures, and attitudinal and cultural factors, which can all play an important part in shaping ICT/ physical mobility relationships.
Minnesota DOT: Testing the Robot Road-Painter
Thursday, November 12th, 2015University of Minnesota-Duluth Associate Professor Ryan Rosandich tests a prototype of a robotic arm he developed to paint messages and markings on roadways. He calls the machine the MnDOT Robot.

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.
We require your support in order to rise to this occasion, to make the most of this opportunity. Please consider making a tax-deductible donation to InfrastructureUSA.org.
