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.

Action Agenda for New Jersey’s Water Infrastructure

New Jersey's Water Infrastructure - Action Plan

JERSEY WATER WORKS (JWW) Executive Summary Water Infrastructure is invisible. People and businesses expect the ready availability of clean, affordable drinking water, safe removal of wastewater and efficient management of stormwater. But when water infrastructure fails — whether through a water or sewer main break, local flooding or pollution swept into a fishing stream — […]

Oroville Dam Spillway Incident: Independent Forensic Report

Monday, January 15th, 2018
Oroville Dam Spillway Incident - Thumb

The Oroville Dam spillway incident was caused by a long-term systemic failure of the California Department of Water Resources (DWR), regulatory, and general industry practices to recognize and address inherent spillway design and construction weaknesses, poor bedrock quality, and deteriorated service spillway chute conditions. The incident cannot reasonably be “blamed” mainly on any one individual, group, or organization.

Fresh Water Becoming Saltier Around the United States

The freshwater salinization syndrome can increase risks to the safety of drinking water and infrastructure. Elevated salt levels in drinking water can contribute to hypertension in people on sodium-restricted diets and is of concern to people requiring kidney dialysis (9). Salinization and alkalinization influence the corrosivity of water, and this can affect leaching of metals from pipes carrying drinking water (9, 68).

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.

Empty Seats, Full Streets: Fixing Manhattan’s Traffic Problem

Tuesday, December 26th, 2017

The rapid growth of app-based ride services such as Uber and Lyft has raised concerns in large U.S. cities such as New York. San Francisco, Chicago and Seattle about their impacts on traffic congestion and public transportation ridership. In New York City, the growth of app-based ride services (often called “Transportation Network Companies,” or TNCs) has raised questions about how anti-congestion plans being developed by Governor Andrew Cuomo and Mayor Bill de Blasio should address TNCs’ contributions to traffic congestion.

A Complete Streets Evaluation of New Orleans and Jefferson Parish

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.
