Ready To Roll: Southeastern Pennsylvania's Regional Electric Vehicle Action Plan
On-road internal combustion engine (ICE) vehicles are responsible for nearly one-third of energy use and one-quarter of greenhouse gas (GHG) emissions in southeastern Pennsylvania.1 Electric vehicles (EVs), including plug-in hybrid electric vehicles (PHEVs) and all-electric vehicles (AEVs), present an opportunity to serve a significant portion of the region's mobility needs while simultaneously reducing energy use, petroleum dependence, fueling costs, and GHG emissions. As a national leader in EV readiness, the region can serve as an example for other efforts around the country."Ready to Roll! Southeastern Pennsylvania's Regional EV Action Plan (Ready to Roll!)" is a comprehensive, regionally coordinated approach to introducing EVs and electric vehicle supply equipment (EVSE) into the five counties of southeastern Pennsylvania (Bucks, Chester, Delaware, Montgomery, and Philadelphia). This plan is the product of a partnership between the Delaware Valley Regional Planning Commission (DVRPC), the City of Philadelphia, PECO Energy Company (PECO; the region's electricity provider), and Greater Philadelphia Clean Cities (GPCC). Additionally, ICF International provided assistance to DVRPC with the preparation of this plan. The plan incorporates feedback from key regional stakeholders, national best practices, and research to assess the southeastern Pennsylvania EV market, identify current market barriers, and develop strategies to facilitate vehicle and infrastructure deployment

Transportation connects Bostonās workers, residents and tourists to their livelihoods, health care, education,
recreation, culture, and other aspects of life quality. In cities, transit access is a critical factor determining
upward mobility. Yet many urban transportation systems, including Bostonās, underserve some populations
along one or more of those dimensions. Boston has the opportunity and means to expand mobility access to
all residents, and at the same time reduce GHG emissions from transportation. This requires the
transformation of the automobile-centric system that is fueled predominantly by gasoline and diesel fuel.
The near elimination of fossil fuelsācombined with more transit, walking, and bikingāwill curtail air
pollution and crashes, and dramatically reduce the public health impact of transportation. The City embarks
on this transition from a position of strength. Boston is consistently ranked as one of the most walkable and
bikeable cities in the nation, and one in three commuters already take public transportation.
There are three general strategies to reaching a carbon-neutral transportation system:
ā¢ Shift trips out of automobiles to transit, biking, and walking;1
ā¢ Reduce automobile trips via land use planning that encourages denser development and affordable
housing in transit-rich neighborhoods;
ā¢ Shift most automobiles, trucks, buses, and trains to zero-GHG electricity.
Even with Bostonās strong transit foundation, a carbon-neutral transportation system requires a wholesale
change in Bostonās transportation culture. Success depends on the intelligent adoption of new technologies,
influencing behavior with strong, equitable, and clearly articulated planning and investment, and effective
collaboration with state and regional partners.Published versio
Investing in America\u27s Surface Transportation Infrastructure: The Need for a Multi-Year Reauthorization Bill: Hearing Before the S. Comm. on Env\u27t & Pub. Works, 116th Cong., July 10, 2019
The Fourth National Climate Assessment, released in November 2018, described the serious impacts of climate change already being felt throughout the U.S., and made clear that the risks to communities all across the country are growing rapidly.
These findings, along with those in the 2018 Intergovernmental Panel on Climate Change (IPCC) report should serve as an immediate call to action. Even if we manage to limit planetary warming to just 2 degrees Celsius, the world will still face increased chances of economic and social upheaval from more severe flooding, droughts, heatwaves, and other climate impacts as well as devastating environmental consequences, the IPCC report warns.
The consensus from leading scientific research academies within the United States and internationally is clear: multiple lines of evidence indicate, and have indicated for years, that our atmosphere is warming, sea levels are rising, the magnitude and frequency of certain extreme weather events is increasing, and that human activity is the primary driver of climate change. As described in the IPCC Special Report, the consensus is that countries around the world must rapidly decarbonize their economies, cutting greenhouse gas emissions in half by 2030 and to near zero by 2050. The U.S. Department of Defense, and leaders within the defense and national security communities, have also recognized climate change as a ānational security issueā that requires adapting military operations and planning to ensure readiness.
Despite our understanding of the consequences we will face and the urgency to act, U.S. GHG emissions from fossil fuel combustion increased by 2.7 percent in 2018, according the Rhodium Group. Clearly more action is needed.
While we all recognize the importance of transportation in our daily lives and for our economy, it is also important to recognize that the transportation sector is the largest contributor of GHG emissions in the United States, and is already facing significant impacts from climate change.
There is an urgent need, therefore, to transition to a low-carbon and more resilient transportation system. Such a transition would not only reduce emissions and fight climate change, it also would bring additional important benefits, including protecting public health by reducing conventional air pollution, providing more mobility options, and driving innovation and economic growth through policy action and through public and private investment
Electric Power Allocation in a Network of Fast Charging Stations
In order to increase the penetration of electric vehicles, a network of fast
charging stations that can provide drivers with a certain level of quality of
service (QoS) is needed. However, given the strain that such a network can
exert on the power grid, and the mobility of loads represented by electric
vehicles, operating it efficiently is a challenging problem. In this paper, we
examine a network of charging stations equipped with an energy storage device
and propose a scheme that allocates power to them from the grid, as well as
routes customers. We examine three scenarios, gradually increasing their
complexity. In the first one, all stations have identical charging capabilities
and energy storage devices, draw constant power from the grid and no routing
decisions of customers are considered. It represents the current state of
affairs and serves as a baseline for evaluating the performance of the proposed
scheme. In the second scenario, power to the stations is allocated in an
optimal manner from the grid and in addition a certain percentage of customers
can be routed to nearby stations. In the final scenario, optimal allocation of
both power from the grid and customers to stations is considered. The three
scenarios are evaluated using real traffic traces corresponding to weekday rush
hour from a large metropolitan area in the US. The results indicate that the
proposed scheme offers substantial improvements of performance compared to the
current mode of operation; namely, more customers can be served with the same
amount of power, thus enabling the station operators to increase their
profitability. Further, the scheme provides guarantees to customers in terms of
the probability of being blocked by the closest charging station. Overall, the
paper addresses key issues related to the efficient operation of a network of
charging stations.Comment: Published in IEEE Journal on Selected Areas in Communications July

A review of electric vehicle charge point map websites in the NSR: Interim report
This interim report is a review of the EV charge point (station) map websites in the North Sea Region (NSR) with the aim to identify if there are any patterns, or any noticeable gaps on the information presented by the interactive EV charge point tools. For each example of the charge point (station) map website, a review has been undertaken by visiting the charge point (station) map website and recording if the site contains the information, which is of key importance from an EV user perspective, for example an interactive map; any information on the charger power of the charge points (stations); the type of connection of the charge points (stations); the addresses of the charge points (stations) and further helpful details
