“Smashing Into Crowds” -- An Analysis Of Vehicle Ramming Attacks, Brian Michael Jenkins, Bruce R. Butterworth

Mineta Transportation Institute

Vehicle ramming attacks are not new. But since 2010 Jihadists have urged their use. Is this the wave of the future, or a terrorist fad? To answer this and other questions the authors expanded and updated the database used in their May 2018 MTI Security Perspective entitled An Analysis of Vehicle Ramming as a Terrorist Threat to include 184 attacks since January 1, 1970. They also reviewed literature and examined some cases in detail. This MTI Security perspective indicates that while not new, vehicle rammings are more frequent and lethal since 2014, although the number of attacks seems to be …

The Link Between Transit Station Proximity And Real Estate Rents, Jobs, People And Housing With Transit And Land Use Planning Implications, Arthur C. Nelson, Robert Hibberd

TREC Final Reports

This report updates and expands prior research in the genre of research that has used economic base analysis (especially shiftshare) and CoStar commercial rent data to estimate the development outcomes to transit. The study period for prior economic base analysis was 2002-2011and census data for 2000 and 2010, as well as CoStar data for 2013. Prior analysis compared development, demographic and housing outcomes associated with those transit systems during the period before the Great Recession (2000 through 2007) and during recession into recovery (2008 through 2011). Though NITC researchers found important differences in outcomes between the study periods of 2000-2007 …

Your Community Gets A B-: Analysis Of The Specific And Curious Realm Of Airport Bond Rating, Richard W. Hawkins, Stephen A. Lemay, Peter M. Ralston

Journal of Transportation Management

Commercial airports are publicly-owned transportation infrastructure, usually funded with bonds. The bond rating decision for these entities thus has important ramifications for bond investors, issuers, airport managers, and even the communities the airports serve, but the rating decision process is not well understood. This paper discusses a simulation of the rating process in two decision environments, including a downgrade. The effect of information framing in an environment of incomplete data is examined using amateur evaluators. Amateur evaluators were utilized to understand how people with limited financial analysis skills would respond when presented with incomplete information and a primed scenario. The …

An Experimental Test Of Green Management Information System Effects On Carrier Selection: Weigh Station And Tollbooth Bypass Technology Adoption, Rodney W. Thomas, Jessica L. Robinson, Jessica L. Darby, Scott Cox, Donnie F. Williams Jr

Journal of Transportation Management

In a highly competitive price-driven industry, carriers are continuously searching for opportunities to differentiate their offerings, minimize operational costs, and appeal to shippers. At the same time, environmental sustainability has evolved from being trendy jargon into a requirement for competitive supply chain management. It is at the intersection of these two modern topics that the current study identifies a new carrier selection attribute based on a specialized type of green management information system. We apply social exchange theory to hypothesize carrier price and green technology adoption effects on shipper purchase intent. The hypothesized direct and interaction effects are tested by …

Social Media And Supply Chain Risk Management: Improving Risk Detection And Supply Chain Resilience, Scott R. Cox, J Kirk Atkinson

Journal of Transportation Management

The introduction of social media has changed the methods by which many individuals, communities, and organizations communicate and interact. The increasing popularity of social media within a business context has forced executives to rethink how they operate their businesses. Chae (2015) observed that the field of supply chain management (SCM) has been lagging in identifying the potential role and use of social media in both research and practice. Recently, greater attention is being given to social media and its potential uses within the supply chain. This paper investigates the potential use for social media as a technology to help with …

The Tumultuous World Of Global Maritime Transportation: A Cautionary Tale For Supply Chain Managers, Kent N. Gourdin

Journal of Transportation Management

The past five years have seen unprecedented changes transform the way goods are moved around the world. The expanded Panama Canal now permits larger vessels as well as simultaneous transits in each direction. Coincidently, steamship lines began purchasing a new generation of bigger ships, forcing ports in the United States to make very large investments in new infrastructure. When examined within the context of other environmental events impacting global trade, the total effect has been to put the maritime industry into a state of flux. This paper will examine these and other important issues before offering conclusions intended to help …

Data From: Updating And Expanding Lrt/Brt/Sct/Crt Data And Analysis, Robert Hibberd, Arthur C. Nelson, Kristina M. Currans

TREC Datasets and Databases

This data supports the LRT/BRT/SCT/CRT Development Outcomes FINAL PHASE.

The FINAL PHASE will allow us to use factor/cluster analysis to create typologies of station areas to assess the extent to which types of stations (as opposed to transit systems as a whole) make a difference in economic development (based on LEHD data), and people (census data) during the periods before, during and after the Great Recession as appropriate for each system and mode. It will also allow us to refine hedonic regression analysis.

Economic And Development Benefits Of Fixed Route Transit Through Denser Housing: A National Assessment, Arthur C. Nelson, Robert Hibberd

TREC Project Briefs

Building upon seven years of research, NITC investigators used economic analysis to determine development outcomes and land use planning implications of different fixed route transit systems (FRT). They have created, analyzed, and shared a nationwide data repository that explores links between transit station proximity and real estate rents, jobs, people, and housing. Earlier research revealed important differences in development outcomes of FRT’s during the 2000’s, but the significantly expanded data repository offers a more representative look at development outcomes after the Great Recession and with 22 new FRT systems added.

The main takeaway from this expanded analysis? Only 5% of …

B-Line Sustainable Urban Delivery: Can Last-Mile Bicycle Delivery Survive The E-Commerce Minefield?, Madeleine Pullman, Jacen Greene, Wanying Shi, Stephan Kaplan

Business Faculty Publications and Presentations

As the population of cities in the western United States continues to boom, the demand for retail and wholesale food has followed suit. To deal with the accompanying increase in traffic and congestion from population and business growth, the city of Portland planned to increase bikeways and reduce the use of single-occupant vehicles to less than 30% of total commuters by 2026. Despite efforts to decrease dependence on vehicles, traffic congestion in Portland
continued to increase, and traditional vehicle delivery in the urban area became less and less efficient. As ride-sharing services and online retailers increased their presence in the …

Congestion Pricing Efficiency And Equity, Michael Manville

PSU Transportation Seminars

Congestion pricing is effective, and efficient, but is it fair? One of the biggest concerns surrounding dynamic road charges is that they will harm low-income people. This seminar examines the equity implications of congestion charging, and argues that road pricing can satisfy the demands of both equity and efficiency.

Horse And Buggy Crash Study Iii: Low Illumination And The Sun’S Glare In Crashes Between Motor Vehicles And Amish / Old Order Mennonite Horse And Buggies, Cory Anderson

Journal of Amish and Plain Anabaptist Studies

The purpose of this study is to identify time periods of particular crash risk through the day for Amish and Old Order Mennonite horse & buggies. As suggested in prior studies, transitional illumination (dawn/dusk) may be a risk to travel because of a lighting situation that lowers visibility, and the sun’s glare at these same times may obstruct motorists’ vision. The speed differences between buggies and motor vehicles are already great; reduced vision compounds the problem of response time. To assess risk, I compare horse and buggy traffic counts to the times of horse & buggy crashes over a nine-year …

Horse And Buggy Crash Study Ii: Overstretching The Slow-Moving Vehicle Emblem's Abilities: Lessons From The Swartzentruber Amish, Cory Anderson

Journal of Amish and Plain Anabaptist Studies

For decades, the Swartzentruber sect of Amish have, for religious reasons, rejected state-level mandates for horse-drawn buggies to display the S.M.V. (slow-moving vehicle) emblem. Court cases in several states have suggested (1) confusion over what the emblem is supposed to accomplish, and (2) questions about the emblem's superiority to alternatives. Synthesizing evidence presented in several court cases involving the S.M.V. emblem and the Swartzentruber Amish, this study clarifies what the S.M.V. emblem can be expected to accomplish and in which domains it reaches its limits. The evidence is organized categorically and presented as a series of cues presented to the …

Horse And Buggy Crash Study I: Common Crash Scenarios Between A Motor Vehicle And The Amish / Old Order Mennonite Horse And Buggy, Cory Anderson

Journal of Amish and Plain Anabaptist Studies

Horse and buggy transportation is spreading as rapidly as its Amish and Old Order Mennonite users are, as are buggy crashes with motor vehicles. This study examines the primary causes of 76 reported horse and buggy crashes in Pennsylvania in 2006. The main crash types identified include a motorist rear-ending a forward-moving buggy, a motorist striking the buggy while attempting to pass, buggy struck while crossing an intersection, and buggy struck while making a left turn. While causative factors varied, major factors include the motorist or buggy driver incorrectly comprehending speed differentials, the motorist acting carelessly around the buggy, and …

Transport Practices In Amish Communities, James Warren, Marcus Enoch

Journal of Amish and Plain Anabaptist Studies

Car ownership is growing in many countries. While beneficial to individuals in many cases, this trend has often resulted in significant economic, social, and environmental costs to society more generally. In researching possible solutions, one approach is to look at particular areas or communities that exhibit less reliance on the car or are even ‘car free’ to some extent, in order to see if lessons can be learned. Accordingly, this study seeks to define and characterize transport practices in Amish communities—in groups located across the United States and Canada—which for religious reasons have eschewed the car. Specifically, the paper draws …

The Safe System Approach: Considerations For Developing A Multi-Layered System, Offer Grembek

PSU Transportation Seminars

While the overarching objective of the transportation system is to provide mobility, it should be developed and operated under the framework of a safe system with the aspirational goal to establish a system on which no road user can be severely or fatally injured. To accomplish such a safe system, it is necessary to effectively harness all the core protective opportunities provided by the system. This includes the street design and operations, user behavior, vehicle design, protection systems, and EMS. The common thread across these layers is speed. This is directly driven by the quadratic relationship between velocity and kinetic …

Webinar: Contextual Guidance At Intersections For Protected Bicycle Lanes, Christopher Monsere, Nathan Mcneil

TREC Webinar Series

Separated bike lanes have become increasingly common around the United States as cities seek to attract the new riders, including people who want to ride but limit their riding because they do not feel comfortable riding with motor vehicle traffic. Planners and engineers are working to identify contextually appropriate, safe, and comfortable designs for intersection locations, where bicyclist paths cross the paths of turning vehicles as well as cross-traffic. This research employed a combination of user surveys and simulations to anticipate expected bicyclist and turning vehicle interactions and bicyclist comfort based on design type and volumes. Findings examine which types …
