The State of Public & Private Electric Vehicle Charging Infrastructure

Thursday, January 18th, 2018
Survey: Are you looking to buy a plug-in vehicle in the next 12 months?

This report looks at the current state of the plug-in vehicle charging landscape within the context of the broader transition from internal combustion vehicles to plug-in vehicles. EVSE deployments and sales largely track with the sales of plug-in vehicles, so we will briefly touch on the broader transition to plug-in battery electric vehicles and how the transition is progressing around the world to set the stage for the EVSE discussion.

2017: The Year in Infrastructure

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.

The Future of Equity in Cities: Infrastructure

Tuesday, January 2nd, 2018
The Future of Equity in Cities - Mobility and Infrastructure

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 […]

Resilience and efficiency in transportation networks

Friday, December 29th, 2017
Fig. 1. Definition of urban areas and assignment of nodes’ population.

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.

A Complete Streets Evaluation of New Orleans and Jefferson Parish

Friday, December 22nd, 2017
Complete streets in New Orleans: Recommended measures

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.

New York City – Unsustainable: Traffic 2018

Friday, December 22nd, 2017

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.

Guest on The Infra Blog: Robert Bolton, Senior Vice President, Arcadis

Robert Bolton, Senior Vice President, Arcadis

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.

City Parks: America’s New Infrastructure

Tuesday, December 12th, 2017

City Parks Alliance releases the latest video in the five-part series, “City Parks: America’s New Infrastructure,” focused on the role of linear parks in providing transportation options to city residents. Featuring Fairmount Park System in Philadelphia, PA, The 606 in Chicago, IL, and The Lafitte Greenway in New Orleans, LA, this video share information on how the parks are providing commuter access to jobs and retail, as well as recreational walking and cycling needs.

Washington, DC: What The Barnes Dance Looks Like

Thursday, December 7th, 2017

A Barnes Dance Intersection (also known as a “pedestrian scramble”) operates differently from a standard traffic signal-controlled intersection and allows pedestrians to cross diagonally while vehicles on all sides of the intersection are stopped at a red signal. In June 2017, DDOT put in place a Barnes Dance at 14th and Irving Street NW, which […]
