Electric Kick Scooters On Sidewalks In Virginia But Not In California? A Review Of How States Regulate Personal Transportation Devices, Kevin Fang, Asha Weinstein Agrawal, Ashley Hooper

Mineta Transportation Institute Publications

Every weekday morning in San Francisco’s SoMa district, a stream of workers disembark from the city’s commuter rail station carrying an assortment of small, wheeled devices—kick scooters, electric skateboards, hoverboards, and more—which they then use to roll on to their offices. These “personal transportation devices” (PTDs)—also called micromobility or microtransit—encompass a growing set of devices that provide low-speed, flexible mobility for individual travelers. In recent years, the number of PTD types and their use has exploded with the introduction of new devices. This Perspective reports findings from a research project reviewing how these PTDs ...

The Use Of Mt. Mazama Volcanic Ash As Natural Pozzolans For Sustainable Soil And Unpaved Road Improvement, Matthew D. Sleep, Morgan B. Masley

TREC Final Reports

Natural pozzolans can be a replacement for portland cement in many applications. Some natural pozzolans are byproducts of industrial processes. Other natural pozzolans, such as volcanic ash, occur naturally. This study determined the suitability of Mt. Mazama volcanic ash as a natural pozzolan and explored innovative uses of the material for roadway improvement. Requirements of natural pozzolans are specified in ASTM C618 – coal fly ash and raw or calcined natural pozzolan for use in concrete. This study concluded that volcanic ash from Mt. Mazama meets chemical requirements of a natural pozzolan. In its unprocessed, natural form, Mt. Mazama volcanic ash ...


Bounded Rank Optimization For Effective And Efficient Emergency Response, Pallavi Madhusudan MANOHAR, Pradeep VARAKANTHAM, Hoong Chuin LAU 2018 Singapore Management University

Bounded Rank Optimization For Effective And Efficient Emergency Response, Pallavi Madhusudan Manohar, Pradeep Varakantham, Hoong Chuin Lau

Research Collection School Of Information Systems

Effective placement of emergency response vehicles (such as ambulances, fire trucks, police cars) to deal with medical, fire or criminal activities can reduce the incident response time by few seconds, which in turn can potentially save a human life. Owing to its adoption in Emergency Medical Services (EMSs) worldwide, existing research on improving emergency response has focused on optimizing the objective of bounded time (i.e. number of incidents served in a fixed time). Due to the dependence of this objective on temporal uncertainty, optimizing the bounded time objective is challenging. In this paper, we propose a new objective referred ...


Optimization Of A Cyclic Express Subway Service, Hai WANG, Jiangang JIN, Jingfeng YANG 2018 Singapore Management University

Optimization Of A Cyclic Express Subway Service, Hai Wang, Jiangang Jin, Jingfeng Yang

Research Collection School Of Information Systems

With rapid population growth and increasing demand for urban mobility, metropolitan areas such as Singapore, Tokyo, and Shanghai are increasingly dependent on public transport systems. Various strategies are proposed to improve the service quality and capacity of bus and subway systems. Express trains-i.e., trains that skip certain stations-are commonly used, because they can travel at higher speeds, potentially reduce travel time, and serve more passengers. In this paper, we study cyclic express subway service (CESS), in which express trains provide routine transport service with cyclic (periodic) station-skip patterns that can be used in daily service. We propose an exact ...


The Policy Trajectories Of Autonomous Vehicles, John Paul MacDuffie 2018 University of Pennsylvania

The Policy Trajectories Of Autonomous Vehicles, John Paul Macduffie

Penn Wharton Public Policy Initiative

Autonomous Vehicle (AV) technology promises to dramatically reduce deaths and economic losses from crashes caused by human error, increase mobility for those with disabilities, and revolutionize the auto industry. Yet legislation to facilitate oversight of the development and deployment of AVs is stalling in Congress. Professor John Paul MacDuffie offers a primer on AV technology policy, and discusses strategies for addressing safety and other public concerns while still facilitating AV innovation in the private sector.


A Survey Of Ride-Hailing Passengers, Steven Gehrke 2018 Boston Metropolitan Area Planning Council

A Survey Of Ride-Hailing Passengers, Steven Gehrke

TREC Friday Seminar Series

In less than a decade, the ride-hailing industry, led by Uber and Lyft, has dramatically transformed the way we travel in our metro regions. Rider adoption of these on-demand mobility services has proceeded much quicker than our understanding of their impacts to our urban transportation systems. Planning for this transformation in personal mobility, which will have unintended consequences, has been made more difficult by the scarcity in meaningful data made available by these ride-hailing companies. Public agencies responsible for managing congestion and transit services are hindered in their ability to successfully plan for the integration of this emergent travel mode ...

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. McAllister 2018 University of Montana, Missoula

Science, Advocacy, Policy, Planning: Tools For Advancing Transportation Equity, Garrett S. Mcallister

Graduate Student Portfolios

The theme of this portfolio is how different tools and approaches can be used for advancing transportation equity. Broadly defined, transportation equity is about fairness in transportation. There are a number of ways this fairness can be assessed. The most common way to assess transportation equity is by looking at the fairness of outcomes, distributed geographically, socially, or even by mode of transportation. Equity can also be defined by the fairness of processes. The first half of the portfolio illustrates some of the problems with the current transportation system and how it is unhealthy (Piece 1) and unjust (Piece 2 ...


Analysis Of The Contribution Of Transportation And Land Use To Citizen Perceptions Of Livability, Rebecca Lewis 2018 University of Oregon

Analysis Of The Contribution Of Transportation And Land Use To Citizen Perceptions Of Livability, Rebecca Lewis

TREC Friday Seminar Series

What is livability? How does the built environment influence resident perceptions of livability? Although livability is a broadly used term and a key goal in land use and transportation plans at the state level, it is unclear whether residents think their neighborhoods are livable and what contributes to their perception of livability. The purpose of the project was to understand how Oregonians, in neighborhoods of varying densities and within Metropolitan Planning Organizations (MPOs), perceive livability at the nexus of transportation and land use. We sought to understand how residents define and perceive livability in three different MPOs in the state ...


Improving Demand Modeling In California's Rail Transit System, Rui Liu 2018 San Jose State University

Improving Demand Modeling In California's Rail Transit System, Rui Liu

Mineta Transportation Institute Publications

This paper analyzes urban rail-fare elasticity and compares the results across four California transit systems. A method of Internet search is adopted to collect monthly transit-fare records from 2002 to 2013. This paper contributes towards improving demand modeling for public transit using more precise and monthly data and applies econometric techniques involving autoregressive integrated moving average (ARIMA) and panel data models. Results show that demand for public transit in California is very inelastic. Any ridership promotion policy may have a heterogeneous impact across transit systems.

In addition, where available, CATPAD contains aggregated information, such as station boardings and service and fare schedules, to provide key context for the disaggregate person-level ...


An Analysis Of Vehicle Ramming As A Terrorist Threat, Brian Michael Jenkins, Bruce R. Butterworth 2018 Mineta Transportation Institute

An Analysis Of Vehicle Ramming As A Terrorist Threat, Brian Michael Jenkins, Bruce R. Butterworth

Mineta Transportation Institute Publications

Ramming attacks in which drivers deliberately plow their vehicles into public gatherings, pedestrians, or bicyclists, have become an increasingly common terrorist tactic. This MTI Security Perspective, by Brian Michael Jenkins and Bruce R. Butterworth analyzes 78 vehicular attacks between January 1973 and April 2018. According to their analysis, it is a growing trend, and a frightening one. The 78 attacks led to 281 deaths and around 1,200 injuries. Sixteen attacks took place between 1973 and 2007, while 62 took place between 2008 and April 2018. Thirty of these occurred in 2017 and the first four months of 2018 alone.

Human Trafficking: Flying Under The Radar, Amber L. Hulsey

Dissertations

The global hegemon, the United States encompasses roughly 57,000 to 63,000 of the roughly 45.8 million slaves present across the world today (Walk Free Foundation 2016a). This dissertation research uses the theoretical lens of Human Security as a unique approach in that it is people-centered, focusing on the individual, rather than the more traditional theories in international relations that emphasize the state as the central actor. This dissertation focuses on the understudied area of human trafficking into and within the United States. More specifically, the objective of this research examines the movement of trafficked persons via air ...


Improving Bicycle Crash Prediction For Urban Road Segments, Krista Nordback, Sirisha Kothuri, Wesley Marshall, Geoff Gibson, Nick Ferenchak 2018 Portland State University

Improving Bicycle Crash Prediction For Urban Road Segments, Krista Nordback, Sirisha Kothuri, Wesley Marshall, Geoff Gibson, Nick Ferenchak

TREC Project Briefs

The 2010 Highway Safety Manual (HSM) provides methods for predicting the number of motor vehicle crashes on various roadway facilities. However, it includes only a rudimentary method for predicting the number of bicycle-related crashes. Despite research demonstrating that bicycle volume is an important factor in estimating number of bicycle crashes, the method does not include the volume of bicyclists using the roadway. To remedy this, this project will investigate the potential of various simplified methods to include bicycle volumes in future versions of the HSM. By studying locations where bicycle traffic volumes, motor vehicle traffic volumes, bicycle collisions, and roadway ...


Transportation And Land Use—What Determines Livability?, Rebecca Lewis, Robert Parker 2018 University of Oregon

Transportation And Land Use—What Determines Livability?, Rebecca Lewis, Robert Parker

TREC Project Briefs

Livability is a key focus of transportation and land use planning throughout the United States, and a concept that has been guiding U.S. Department of Transportation policy since 2009. In Oregon, the state’s long-range transportation plan identifies “enhancing livability” as a key outcome, but little research has tackled how these planning efforts contribute to residents’ perceptions of livability. This project seeks to fill this research need by exploring the question, “How do residents understand the connection between transportation and land use planning, and its association with livability?”
