On-demand ridesourcing services from transportation network companies (TNCs), such as Uber and Lyft, have reshaped urban travel and changed externality costs from vehicle emissions, congestion, crashes, and noise. To quantify these changes, we simulate replacing private vehicle travel with TNCs in six U.S. cities.
Many cities are rolling out bike share programs. However, few studies have evaluated how bike share systems (BSS) are used to quantify their sustainability impacts. This study proposes a Bike Share Emission Reduction Estimation Model (BS-EREM) to quantify the environmental benefits from bike share trips and compare the greenhouse gas (GHG) emission reductions from BSS in eight cities in the United States, including New York, Chicago, Boston, Philadelphia, Washington D.C., Los Angeles, San Francisco, and Seattle. The BS-EREM model stochastically estimates the transportation modes substituted by bike share trips, considering factors such as trip distance, trip purpose, trip start time, the accessibility of public transits, and historical distributions of transportation mode choices.
This paper synthesizes and reviews all literature regarding autonomous vehicles and their impact on GHG emissions. The paper aims to eliminate bias and provide insight by incorporating statistical analysis.
"In this paper we put together a list of the basic instincts that drive and contain travelers' behavior, showing how they mesh with technological progress and economic constraints."
Increasing automation of vehicles presents may unknowns and concerns, the most important being safety, both in terms of road safety and cyber security. This report examines how these safety concerns will need to be addressed with emerging autonomous technologies by applying the principles of the "Safe System."
Rural Americans are less likely to own home broadband or a smartphone than suburban or urban Americans. This low percentage of adoption may be partly due to a lack of sufficient infrastructure to support high-speed internet.
This paper provides a review of recent studies of rail transit's impact on property values and discusses the types of impacts rail transit can have on properties. It also outlines the reasons for contradictions between results of different studies.
As parking demand declines, some developers and designers are thinking about the long term uses of parking garages and designing them to be able to adapt to changing future land use needs.
With the rise of e-commerce, Americans are demanding more deliveries. However, with declining warehouse availability, congested streets and limited curb access, the U.S.’s infrastructure may not be able to handle the increasing demand.
Despite national averages of shrinking transit ridership, seven United States cities have seen increased ridership. These cities have seen growth because of their efforts to improve or expand their bus services.
The relationship between transit success and density is one that should be considered when planning transportation. Transit lines need to consider cost per passenger-mile in order to ensure financial feasibility. Some scholars suggest minimum density thresholds for successful transit of different types, but these rules do not always represent accurate ridership numbers. However, higher density in cities generally makes transit more feasible.
Robin Chase, co-founder and former CEO of Zipcar and cofounder of NUMO, discusses the misconceptions around Mobility as a Service and its potentials for public benefit.
This article is a literature review of the definition and effects of urban sprawl for the purpose of implementing planning policies that discourage sprawl.
The report is intended to provide guidance to Australia and New Zealand in planning road changes for the introduction of automated vehicles. Key issues that are discussed in this report include physical infrastructure, digital infrastructure, and road operations. The analysis of each issue includes different possible use cases of automated vehicles and includes discussion of optimal conditions required to support the introduction of automated vehicles.
Metro data enables deep analysis of cyclist and pedestrian activity including popular or avoided routes, peak commute times, intersection wait times, and origin/destination zones. Metro processes this data for compatibility with geographic information system (GIS) environments.
This policy paper focuses on the primary concept of the street as space that can be repurposed – real estate that can be allocated in similar or different ways than done currently. Cities generally refer to this publicly owned and regulated space from one side of the street to the other as the right of way (ROW). Our focus is on the centrality of the ROW in dictating many other community functions and values – transportation and otherwise. And our particular bias is to focus on the opportunities that AV technology is likely to create to rethink how the ROW is allocated, so that our communities can meet their substantial and unique environmental, social, and economic challenges.
The Mobility Hub Reader’s Guide is meant to provide guidance and inspiration for city staff, property owners, developers, designers, transit agencies, and community members for enhancing project developments and public right-of-way improvements in proximity to existing or new transit stations with amenities, activities, and programs to support multi-modal connectivity and access.
Williams Goldhagen draws from recent research in cognitive neuroscience and psychology to demonstrate how people’s experiences of the places they build are central to their well-being, their physical health, their communal and social lives, and even their very sense of themselves. From this foundation, Goldhagen presents a powerful case that societies must use this knowledge to rethink what and how they build: the world needs better-designed, healthier environments that address the complex range of human individual and social needs.
"Connected and automated vehicle (CAV) technologies have the potential to change transportation on a global scale. These technologies could improve safety, significantly alter transportation costs, and change traffic patterns and congestion." This time is now to begin having these conversations about how CAVs may integrate into our cities and the impact they could have on land use.
This blog talks about how the autonomous vehicles will change the built environment such as street design, parking infrastructure, public space, etc. It also mentions how different modes can be integrated with the change of built environment.
The storm clouds of sprawl addiction had been gathering for years, but it took the Meltdown and the ensuing Great Recession to make it clear just how damaging that addiction had been to the health of cities across the US and abroad. Sprawl has two really big things going for it, but three even bigger things now going against it which are poised to turn the tide against the pattern of sprawl.
Automated vehicle (AV) policy development and assessment is a difficult and complicated process. Today’s road and vehicle policies are the product of a hundred years of lessons learned. They generally address five areas: safety, efficiency, mobility, convenience, and impact on the environment. Now the prospect-turned-reality of automated vehicles entering public roadways has opened up a number of new policy-related questions. Is it enough to simply modify current road and vehicle policies or will new policies need to be developed addressing much broader aspects of the transportation system? How can these policies be developed to accommodate technologies that either do not yet exist or are only now being tested on the road in constrained environments? Perhaps most importantly, how can policy influence technological design to safely operate with other road users and can we look ahead to have a better view of potential unintended consequences?
"This paper explores the relationships between transportation, land use and taxation. It investigates how current land tax and regulatory practices affect the amount of land devoted to roads and parking facilities, and how this affects transport patterns. It discusses ways to measure the amount of land devoted to transport facilities, examine how this varies under different circumstances, estimate the value of this resource, evaluate how tax policies and regulations policies treat this land, and analyze whether current practices are optimal in terms of various economic and social objectives."
The main objective of this research project is to provide FDOT with information and guidance on how best to begin to prepare for a future in which AV technology first takes root and then takes over the market. The FSU Research Team is investigating the potential impacts of widespread adoption of AV technology on the transportation network and urban form for four key land use and transportation nodes that are vital to the welfare of the State of Florida: Downtown, Office/Medical/University Center, Urban Arterial, and Transit Neighborhood. To accomplish this, the FSU Research Team engaged one-hundred planners, engineers, industry professionals, and public officials in a facilitated visioning session at the 2015 Florida Automated Vehicle Summit (FAV Summit). During this session the research team gathered input on how AVs will impact our communities and how the built environment will need to adapt to accommodate AVs in the coming decades.
"In response to the Trump administration’s withdrawal of support for the international Paris Climate Agreement last year, the City Council adopted Resolution 31757, affirming Seattle's commitment to the goals established in the Paris Agreement, and directing the Office of Sustainability & Environment (OSE) to identify the actions necessary to do our part to limit warming to 1.5 degrees Celsius. The resulting actions, developed under the leadership of Mayor Durkan, reflect a tipping point in the transition to Seattle’s zero emissions future. They are designed to move beyond incremental change and fundamentally reshape our building and transportation systems for a fossil fuel-free future."
"Our City of the Future: Technology and Mobility report is meant to help city leaders understand, imagine and plan for the coming changes in the urban environment that will affect how we all move from one place to another."
"This paper provides a review of scenarios on these issues to date. Although some scenario studies provide useful insights about urban growth and change, very few consider detailed impacts of AVs on urban form, such as the density and mix of functions, the layout of urban development and the accessibility of locations, including the distance to transit."
This white paper will discuss the non-technological trends logistics managers much know and then will hone in on the technologies that will impact the logistics in 2018.
This paper introduces Metrolinx’s recently released Mobility Hub Guidelines and highlights two key aspects of the document: the importance of classifying the current and planned urban context and transportation function at a mobility hub, and methods to overcome challenges in achieving both transport and placemaking roles.
The Atlanta Regional Commission (ARC) has, through scenario planning, already begun to consider the effects that emerging technologies such as AVs and accelerated broadband might have on travel patterns. This report moves another step forward. It identifies and explores transportation technology trends, their potential impacts, and their policy implications, both generally and those specific to the Atlanta region. The result is intended to help support the Atlanta region in developing a regional transportation technology program to prepare for and take advantage of technology innovations in support of the region’s goals.
The continued use of minimum parking requirements is likely to encourage automobile use at a time when metropolitan areas are actively seeking to manage congestion and increase transit use, biking, and walking. Widely discussed ways to reform parking policies may be less than effective if planners do not consider the remaining incentives to auto use created by the existing parking infrastructure. Planners should encourage the conversion of existing parking facilities to alternative uses.
It is no secret that transit systems are chronically short in funding and increases to their budgets are tough to nail down. This article describes the common way that this funding is being sourced and why it may not be the best way.
This report includes information on the first of many research tasks planned for the partnership between SDOT and the Urban Freight Lab. This is the first assessment in any American city of the privately-owned and operated elements of the Final 50 Feet of goods delivery supply chains. These include private truck freight bays and loading docks, delivery policies and operations within buildings located in Center City.
This article is a review of Adonia Lugo's book: "Bicycle / Race: Transportation, Culture, & Resistance". The book talks about issues of race and class in bicycle culture. It is a call to refocus bicycle-planning beyond physical infrastructure to include human-infrastructure that centers on the stories and identities that shape how, where, when, and why we travel.
Cycling advocates have proposed a network of bicycle paths connecting the suburbs and city center, comparing their plan to the region’s rapid transit system.
This article describes the potential need for an increase in taxes for City municipalities to maintain their budgets as a decrease in speeding and red-light tickets had the potential to become nonexistent due to autonomous vehicles.
"In the United States, road infrastructure funding is declining due to an increase in fuel efficiency and the non-adjustment of fuel taxes to inflation. Legislation to tax plug-in vehicles has been proposed or implemented in several states. This paper assesses (1) the magnitude of the decline in federal fuel tax revenue caused by plug-in vehicles and (2) quantifies the revenue that could be generated from a federal plug in vehicle registration fee.
Autonomous vehicles will have a major impact on parking facility designs in the future. Compared to regular car-parks that have only two rows of vehicles in each island, future car-parks (for autonomous vehicles) can have multiple rows of vehicles stacked behind each other. Although this multi-row layout reduces parking space, it can cause blockage if a certain vehicle is barricaded by other vehicles and cannot leave the facility. To release barricaded vehicles, the car-park operator has to relocate some of the vehicles to create a clear pathway for the blocked vehicle to exit. The extent of vehicle relocation depends on the layout design of the car-park. To find the optimal car-park layout with minimum relocations, we present a mixed-integer non-linear program that treats each island in the car-park as a queuing system. We solve the problem using Benders decomposition for an exact answer and we present a heuristic algorithm to find a reasonable upper-bound of the mathematical model. We show that autonomous vehicle car-parks can decrease the need for parking space by an average of 62% and a maximum of 87%. This revitalization of space that was previously used for parking can be socially beneficial if car-parks are converted into commercial and residential land-uses.
"This paper presents a comprehensive discussion of the value capture mechanisms that cities can and do use to help finance their public transport systems. It highlights the most important findings from the literature and adds to it with new insights gained through case studies of public transit finance in six European and American cities. The objective is to inform a lively and productive dialogue on non-fare sources of public transport finance, and ultimately to find the best ways to finance the maintenance and extension of transit service in cities around the world."
This edition of the Blueprint is organized into three parts, taking the reader through the principles and political structures that underscore and shape our vision of the future, key policy choices around transit, pricing, freight, and data that can reshape our cities, and finally, exploring the sweeping vision for city streets of the future: Shaping the Autonomous Future Today, Policies to Shape the Autonomous Age, and Design for the Autonomous Age
"The purpose of this research is to help cities mitigate these issues and answer any questions related to scooter implementation with a thorough understanding of scooter regulations. This research is designed to provide cities a range of practices for scooter regulations without elevating any regulatory practice as best. Ultimately, this research can be used as a guide for cities when signing an agreement with a scooter company."
Urban Mobility in a Digital Age is a transportation technology strategy designed to build on the success and innovation of the City of Los Angeles and its Department of Transportation (LADOT) as regulator and transportation service provider in a complex and evolving ecosystem of public and private services.
Warren Logan, a Bay Area transportation planner, has new ideas about how to truly engage diverse communities in city planning. Hint: It starts with listening.
Lawyers of a luxury condo in New York City have been brought into the debate surrounding the construction of a new bike lane that over took city parking in front of the condos.
As public transit stagnates in most U.S. cities, central Seattle continued its rapid growth by adding roughly 10,000 morning transit commuters last year, new local data show.
Connected and fully automated or autonomous vehicles (CAVs) are becoming increasingly viable 23 as a technology and may soon dominate the automotive industry. Once CAVs are sufficiently 24 reliable and affordable, they will gain greater market penetration, generating significant economic 25 ripple effects throughout many industries. This paper synthesizes and expands upon analysis from 26 multiple reports on the economic effects of CAVs across 13 different industries and the overall 27 economy.
This report is an analysis of 153 "state of the city" speeches by mayors between January and April of 2019. They have been analyzed to identify the 10 major issues cities are talking about and other major issues that are being prioritized across the country.
This Strategic Plan is designed to help the East-West Gateway Council of Governments (EWG) to better position itself to prepare for emerging transportation technologies in its planning and investment decision making processes.
This paper examines the suburbanization of warehousing and trucking activity within US metropolitan areas between the 1980s and the present using Gini indices as a measure of concentration. While historical work exists on the relocation of transportation and warehousing activity to suburban locations, there has been little to document the most recent shifts in warehousing and logistics. This research does so via spatial analysis of Economic Census data, finding that while most US metropolitan areas have experienced decentralization in the spatial distribution of freight-related activity, there is also some growth in core counties, indicating that a more complex process is going on than simple suburbanization.
This paper discusses the current and future state of AVs, and the implications for policy at the federal, state, and local levels. It does not intend to summarize all the research nor provide new analysis of the potential implications of AVs. The goal is to provide concrete and substantive recommendations for policymakers in order to responsibly deploy AVs on public roads.
Upon the roll-out of AVs into our streets, the importance of public and private sector partnerships are emphasized. With increased mobility, the demand for private rides could be increased and therefore increase congestion in our streets.
With its 1950s aesthetic intact, Knightley’s Garage is more than a kitschy throwback to the past. Wichita’s repurposed parking facility may actually be an indication of things to come. As personal auto ownership declines in urban downtowns, car-related urban infrastructure is increasingly underused. Some garages, like Knightley’s, are ripe for adaptive reuse. Others are being constructed from scratch in ways that will allow them to be repurposed down the road.
Summary of America's Transportation Infrastructure Act.
This article looks at how "retailers are honing their distribution center strategy to meet current e-commerce demands.
This whitepaper helps to stimulate debate over the proper way to introduce autonomous vehicles into society, with a hope that it leads to greater collaboration among all stakeholders about how to tackle the issue of congestion in autonomous future.
This University of Washington (UW) study focuses on a strategy to manage TNC driver stops when picking up and dropping off passengers with the aim of improving traffic flow in the South Lake Union (SLU) area. SLU is the site of the main campus for Amazon, the online retail company. The site is known to generate a large number of TNC trips, and Amazon reports high rates of ride-hailing use for employee commutes. This study also found that vehicle picking-up/dropping-off passengers make up a significant share of total vehicle activity in SLU. The center city neighborhood is characterized by multiple construction sites, slow speed limits (25 mph) and heavy vehicle and pedestrian traffic.
Spin is placing docking stations for its scooters at locations across the District and Northern Virginia where users can pick up and return the rented equipment. Spin said the charging stations, on private property, will not only keep the scooters powered up but will also bring some order to sidewalks where the devices are often left lying around.
Occasionally, change occurs so rapidly it seems the world is spinning faster than ever. Technology changes occurring in roadways and bridges today are amazing, to say the least. Motorists will soon experience roadway technology never imagined in the past. The transportation sector is definitely a change leader in the U.S.
In many countries the revenue from gasoline taxes is used to fund highways and other transportation infrastructure. As the number of electric vehicles on the road increases, this raises questions about the effectiveness and equity of this financing mechanism. In this paper, we ask whether electric vehicle drivers should pay a mileage tax.
As more states and cities consider taxes on TNC services, policymakers should be cautious and thoughtful about how their decisions affect transportation behavior. As services like TNCs proliferate around the globe, it is important to understand what these fees are, what purpose they intend to serve, and how they fit into broader metropolitan transportation policies.
"The Future of Equity in Cities seeks to take these core issues and forecast the opportunities and challenges to come in cities not just today, but in the decades to come through an analysis of long-range planning, an examination of on-the-ground programming of inclusive economic growth, and by seeking to better understand the public safety challenges that cities will face far into the future."
Depending on how you look view transportation, bikes and scooters are the key to future, clean urban mobility or a sideshow that distracts from maintaining mobility across large metropolis. But the basic problem – the reason we’re having a hyper-emotional discussion about these transportation modes on both sides – is that we’re not framing the issue right.
As more people make the shift to sustainable mobility options like e-scooters, cities are evolving their transportation infrastructure to combat car dominance and to allow human-scaled modes to thrive. In addition to creating dedicated spaces for people to ride shared micro-mobility devices, this transition also includes creating space for them to park when not in use. To explore how cities should think about parking and micro-mobility, Bird sat down for a conversation with parking expert Donald Shoup.
According to case studies, transit systems not in a state of good repair are particularly vulnerable when unanticipated events occur. This can cost a local or regional economy millions of dollars in repairs and lost revenue. Along with the net gains or losses at stake to the U.S. economy, the condition of public transit infrastructure has regional and local implications. As cities throughout America compete to retain key occupations and businesses, the condition and quality of public transit infrastructure play a growing role in what makes a thriving regional economy. The total SGR (State of Good Repair) backlog was estimated to be at $89.9 billion in 2015, and is continuing to grow. Six case studies provide detailed examples of how different agencies are dealing with SGR issues.
