The […]

2017 was, by many accounts, a turbulent year. Infrastructure was no exception.
Whether due to new political paradigms, unprecedented natural disasters or new funding opportunities, American infrastructure faced a wide range of challenges throughout the year. Here, we recount some of the key infra topics that shaped discussion–and action–in 2017.

NATIONAL LEAGUE OF CITIES In order to examine factors at the nexus of equity, mobility and technology, we analyzed long range transportation plans from the 50 largest U.S. cities. In 19 of these cities, there were up-to-date (adopted after 2010) municipal transportation plans available. The remaining plans in the analysis are regional long-range transportation plans. Mobility […]

It is widely understood that roadway infrastructure is expensive, both in acquiring land for rights-of-way and in construction of improvements, and thus, decisions regarding alignment, crossing, and access made over a period of decades may have long-lasting consequences that are observable in traffic data today. Consequently, urban areas exhibit different unintentional traffic characteristics, including delays under normal and random stress conditions. Investments motivated exclusively by expected efficiencies under normal operating conditions are unreliable safeguards against loss of efficiency under stress conditions. Therefore, new analytic tools are required that allow designers to assess the adaptive capacity of roadway infrastructure and assess the potential of new investments to provide enhanced resilience.

Complete Streets is a fundamentally different approach to transportation planning, design, and engineering than the status quo of the last half century. It requires that all aspects of decision-making and implementation consider the needs of all people who use a road, regardless of age, ability, or mode of transportation. Streets are viewed as more than ways to move as many vehicles as possible. They are public spaces that connect and contribute to everything that surrounds them.

Subway reliability is way down, and the bus system is shedding riders at an alarming rate. And because transit is so unreliable, today New York is accommodating growth in cars, in the form of the tens of thousands of Uber and Lyft vehicles we now find on our streets each day.

We looked at 100 cities on a global basis and not one US city made it into the top 20. The highest ranking city was New York City, and they came in at number 23. Probably the biggest challenge that all of the US cities face is the continued dependency on passenger-car travel. We don’t have nearly as well developed metro systems or transit systems for sharing or using alternative means–whether it’s walking or bicycles or other methods of getting around. That’s the big challenge for the US cities, is to look at how they go about diversifying their transportation options.

PennDOT operates one of the most ambitious and comprehensive public-private partnership (P3) programs in the nation. The featured projects bring value to Pennsylvania by significantly reducing structurally deficient bridges, supporting motorist safety, enhancing mass transit and rail service, and in some cases, generating new revenue to support future investment. –Pennsylvania Department of Transportation on YouTube
