The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership, Edgar Bertini Ruas
The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership, Edgar Bertini Ruas
PSU Transportation Seminars
With the emergence of several new providers of shared mobility services, such as Uber, Biketown and Car2go, there has been the promise of changes to the traditional way of owning and using a vehicle. One potential consequence of the new mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing the amount of space dedicated to parking. This thesis aims to asses the extent to which new shared mobility and transportation policy strategies (especially parking requirements and transit pass availability) relate to vehicle ownership among residents of multifamily dwellings. …
Scenarios For Adoption Of Autonomous Vehicle Technologies In Freight, Sabya Mishra
Scenarios For Adoption Of Autonomous Vehicle Technologies In Freight, Sabya Mishra
PSU Transportation Seminars
Innovation adoption research has largely ignored organizational adoption, and little work has been done to understand or predict the adoption of innovations by freight organizations. Among the existing innovation adoption theoretical and methodological approaches this seminar will explore which are most appropriate methods for freight organizational adoption. The seminar will present a disaggregate market penetration model for freight transportation organizations adopting connected autonomous vehicle (CAV) technology and demonstrate an application using a case study area in Memphis, TN. The seminar will highlight ongoing and future organizational adoption research for CAVs, and other innovations.
A Survey Of Ride-Hailing Passengers, Steven Gehrke
A Survey Of Ride-Hailing Passengers, Steven Gehrke
PSU Transportation Seminars
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 …
Analysis Of The Contribution Of Transportation And Land Use To Citizen Perceptions Of Livability, Rebecca Lewis
Analysis Of The Contribution Of Transportation And Land Use To Citizen Perceptions Of Livability, Rebecca Lewis
PSU Transportation Seminars
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: …
Fhwa Guidebook For Measuring Multimodal Network Connectivity, Joseph Broach
Fhwa Guidebook For Measuring Multimodal Network Connectivity, Joseph Broach
PSU Transportation Seminars
In 2016 the United States Department of Transportation (USDOT) Federal Highway Administration (FHWA) published a Guidebook for Developing Pedestrian and Bicycle Performance Measures that presents methods for measuring walking and bicycling performance and activities and embedding them into the transportation planning and decisionmaking process (U.S. Department of Transportation 2016). Building on the 2016 guidebook, this resource focuses on pedestrian and bicycle network connectivity and provides information on incorporating connectivity measures into state, metropolitan, and local transportation planning processes.
Connectivity measures can help transportation practitioners identify high priority network gaps, implement cost-effective solutions that address multiple needs, optimize potential co-benefits, and …
Transportation Impacts Of Affordable Housing: Informing Development Review With Travel Behavior Analysis, Amanda Howell
Transportation Impacts Of Affordable Housing: Informing Development Review With Travel Behavior Analysis, Amanda Howell
PSU Transportation Seminars
Planning for affordable housing is challenged by development policies that often do not differentiate between the travel patterns of residents of market-rate housing and those living in affordable units. The development review process generally requires an evaluation of the anticipated additional transportation demand that new development places on the system and an assessment of fees or improvements to mitigate these impacts.
However, industry standard guidelines for assessment of travel demand outlined within the Institute of Transportation Engineers (ITE) Trip Generation Handbook have been focused solely on vehicle trip rates for these traffic impact analyses. Given the public goals of providing …
Transit Demand Analysis And User Classification Using Automatic Fare Collection (Afc) Data, Alireza Khani
Transit Demand Analysis And User Classification Using Automatic Fare Collection (Afc) Data, Alireza Khani
PSU Transportation Seminars
Development of origin-destination demand matrices is crucial for transit planning. The development process is facilitated by transit automated data, making it possible to mine boarding and alighting patterns on an individual basis. This research proposes a novel stochastic trip chaining method which uses Automatic Fare Collection (AFC) and General Transit Feed Specifications (GTFS) data to infer an origin-destination (O-D) matrix.
Road Diet V2.0 - Road Diet With Roundabouts, Michael Williams
Road Diet V2.0 - Road Diet With Roundabouts, Michael Williams
PSU Transportation Seminars
How can we go one step, or one lane, further than the standard road diet? Roundabouts allow a road diet to reduce the final number of lanes from three to two.
Questions arise when roundabouts are used with a road diet. What traffic volumes are supportable? Will the roundabouts fit within existing intersections? What does current guidance tell us about this approach?
Michael Williams will present his work on creating a sequel to FHWA’s Road Diet Informational Guide. This work is intended to provide a feasibility determination tool for the application of this approach to existing corridors. Data from Bird …
Evaluation Of Route Changes Utilizing High-Resolution Gps Bus Transit Data, Travis Bradley Glick
Evaluation Of Route Changes Utilizing High-Resolution Gps Bus Transit Data, Travis Bradley Glick
PSU Transportation Seminars
Congestion and travel delay on urban roadways can influence operating costs and service attractiveness. This research uses high resolution bus data to examine sources of delay on urban arterials. A set of tools was created to help visualize trends in bus behavior and movement; this allowed larger traffic trends to be visualized along urban corridors and urban streets. By using buses as probes and examining aggregated bus behavior, contoured speed plots can be used to understand the behavior of roadways outside the zone of influence of bus stops. Speed plots can be utilized to discover trends and travel patterns with …
Exploring The Determinants Of Vulnerable Road Users’ Crash Severity In State Roads, Álvaro Caviedes
Exploring The Determinants Of Vulnerable Road Users’ Crash Severity In State Roads, Álvaro Caviedes
PSU Transportation Seminars
Part of the Student Presentations from TRB
Pedestrians and bicyclists are the most vulnerable road users and suffer the most severe consequences when crashes take place. An extensive literature is available for crash severity in terms of driver safety, but fewer studies have explored non-motorized users’ crash severity. Furthermore, most research efforts have examined pedestrian and bicyclist crash severity in urban areas. This study focuses on state roads (mostly outside major urban areas) and aims to identify contributing risk factors of fatal and severe crashes involving pedestrians and bicyclists in state roads. The results seem to suggest that besides improvements …
