Towards Effective Design Treatment For Right Turns At Intersections With Bicycle Traffic, David Hurwitz, Mafruhatul Jannat, Jennifer Warner, Christopher M. Monsere, Ali Razmpa

Civil and Environmental Engineering Faculty Publications and Presentations

The overall goal of this research was to quantify the safety performance of alternative traffic control strategies to mitigate right-turning vehicle-bicycle crashes at signalized intersections in Oregon. The ultimate aim was to provide useful design guidance to potentially mitigate these collision types at the critical intersection configurations. This report includes a comprehensive review of more than 150 scientific and technical articles that relate to bicycle-motor vehicle crashes. A total of 504 right-hook crashes were identified from vehicle path information in the Oregon crash data from 2007-2011, mapped and reviewed in detail to identify the frequency and severity of crashes by …

Household Income And Vehicle Fuel Economy In California, Christopher E. Ferrell, David B. Reinke

Mineta Transportation Institute

This white paper presents the findings from an analysis of the fiscal implications for vehicle owners of changing from the current statewide fuel tax to a “road user charge” (RUC) based on vehicle-miles traveled (VMT). Since 1923, California’s motor vehicle fuel tax has provided revenue used to plan, construct, and maintain the state’s publicly funded transportation systems. Over time, improvements in vehicle fuel efficiency and the effects of inflation have reduced both the revenue from the fuel tax and its purchasing power. Thus, there is growing interest among policy makers for replacing the state’s per-gallon fuel tax with an RUC …

Where Are The Passengers? A Grid-Based Gaussian Mixture Model For Taxi Bookings, Meng-Fen Chiang, Tuan Anh Hoang, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Taxi bookings are events where requests for taxis are made by passengers either over voice calls or mobile apps. As the demand for taxis changes with space and time, it is important to model both the space and temporal dimensions in dynamic booking data. Several applications can benefit from a good taxi booking model. These include the prediction of number of bookings at certain location and time of the day, and the detection of anomalous booking events. In this paper, we propose a Grid-based Gaussian Mixture Model (GGMM) with spatio-temporal dimensions that groups booking data into a number of spatio-temporal …

Examining The Right To Bicycle: Synergies And Tensions Between Human Rights, Civil Rights, And Planning For Cycling, Aaron Golub

PSU Transportation Seminars

Securing and expanding the broad right to bicycle, including the right to adequate and safe street space and related infrastructure for cycling along with other policies and protections for cyclists, is the obvious goal of cycling advocacy efforts in their various forms. All rights are situated within frameworks for promulgating and insuring they are honored, and the right to cycling is no different. This project investigates how the right to bicycle falls within various rights frameworks, focusing on broad human rights and civil rights frameworks while reflecting as well on traffic safety codes and transportation planning frameworks. While certain aspects …

Webinar: Transport Cost Index: A New Comprehensive Performance Measure For Transportation And Land Use, Liming Wang

TREC Webinar Series

Recent federal and state policies are placing increasing emphasis on using comprehensive transportation performance measures to guide transportation decision making processes covering policy areas ranging from mobility, safety, economy and livability, to issues of equity and environment. While it is relatively easy to build consensus on mobility measures that center on the transportation system alone, it is much harder for performance measures to incorporate both transportation and land use, loosely defined as accessibility measures, even with continuous efforts to catalog and design such measures.

Two projects at PSU sponsored by Oregon DOT and National Institute of Transportation Communities (NITC) aim …

The Trade-Offs Between Population Density And Households' Transportation-Housing Costs, Haizhong Wang

PSU Transportation Seminars

As metropolitan area governments and others promote density-promoting “smart growth” policies, finer analysis is needed to quantify the impact of such policies on households' transportation and housing costs. Existing research suggests that households in urban areas trade-off between housing costs and transportation costs, but does not explore how policies to increase urban densities might explicitly impact this balance. Furthermore, the research does not adequately distinguish between the effect of urban area density and the effects of other factors associated with urban area density (e.g metropolitan area size and household incomes) on housing costs. This research uses the 2000 Census Public …

The Backstory: How Livablestreets Advocates Changed Boston, Jeffrey Rosenblum

PSU Transportation Seminars

Local grassroots advocacy organizations play a critical role in shaping the future of cities but receive very little attention in research, especially insofar as understanding the most effective tactics that should be used by these organizations to achieve their objectives. When LivableStreets Alliance was founded in 2005, The City of Boston had 3/8 of one mile of bicycle lanes. Over the past decade, we have seen a sea change. Boston has published a nationally-recognized Complete Streets Guide, MassDOT has incorporated cycle-track designs into several federally-funded projects, and highway overpasses are slated for removal. What is LivableStreets’ role in shifting policy, …

Affordable Housing As A Prerequisite For A Safe, Healthy, Equitable Transportation System: Evidence From A Nationwide Evaluation Of Location Efficiency Within The Low-Income Housing Tax Credit (Lihtc) Program, Arlie Steven Adkins

PSU Transportation Seminars

Mountains of research over the last several decades show that how we get around and how much physical activity we get are closely linked with the built environment of the neighborhoods where we live. This means that the health, economic, and environmental benefits associated with active travel and transit are place-based and that affordable housing in walkable, location efficient places needs to be thought of as a critical component of planners’ efforts to provide safe, healthy, and equitable transportation systems. This talk will provide an overview of the links between affordable housing and transportation planning and present research findings from …

Evaluation Of A Shared Space Alternative In Morgantown, Wv, Avinash Unnikrishnan

PSU Transportation Seminars

Pedestrian and vehicle movement conflicts and the associated safety and efficiency issues have always been addressed in traffic engineering based on the principle of separation through bridges, tunnels, or signals. Pioneered by Hans Monderman, shared space is a new approach in transportation design which inverts this paradigm of separation and designs streets with no demarcations or access restrictions. Shared space has been implemented in a number of cases in Europe with improved efficiency and safety. This research focuses on a specific case study for analyzing the possible implementation of shared space in the United States on the West Virginia University …

Transportation Leadership Education: Portland Traffic And Transportation Course A Case Study And Curriculum, Nathan Mcneil

Urban Studies and Planning Faculty Publications and Presentations

The Portland Traffic and Transportation course serves a number of different purposes. On one hand, it is designed to develop citizens who are informed about the transportation system, including how it got where it is today, what agencies and actors play a role in its operation and development, and how they, as citizens, play a role in its future. In this sense, there is a goal of broadening and deepening the existing knowledge about the system among the general population. On the other hand, there is an implicit goal of encouraging participation in the system with the understanding that doing …

Understanding Interactions Between Drivers And Pedestrian Features At Signalized Intersections, Pei-Sung Lin, Achilleas Kourtellis, Zhenyu Wang, Rui Guo

CUTR Faculty Journal Publications

Florida experienced serious pedestrian safety problems and had the highest pedestrian fatality rate in the U.S. from 2008–2011. Pedestrian safety at signalized intersections is the most serious concern due to frequent and severe conflicts between vehicles and pedestrians. Pedestrian features directly related to pedestrian safety are used to increase driver compliance behaviors and reduce vehicle-pedestrian conflicts. This project aimed to explore driver behaviors at signalized intersections with four identified pedestrian features—“STOP HERE ON RED,” “NO TURN ON RED,” “TURNING VEHICLES YIELD TO PEDESTRIANS,” and “RIGHT ON RED ARROW AFTER STOP” signs—by using an innovative safety data source, the Strategic Highway …

Synergistic Interactions Of Dynamic Ridesharing And Battery Electric Vehicles Land Use, Transit, And Auto Pricing Policies, Caroline Rodier, Farzad Alemi, Dylan Smith

Mineta Transportation Institute

It is widely recognized that new vehicle and fuel technology is necessary, but not sufficient, to meet deep greenhouse gas (GHG) reductions goals for both the U.S. and the state of California. Demand management strategies (such as land use, transit, and auto pricing) are also needed to reduce passenger vehicle miles traveled (VMT) and related GHG emissions. In this study, the authors explore how demand management strategies may be combined with new vehicle technology (battery electric vehicles or BEVs) and services (dynamic ridesharing) to enhance VMT and GHG reductions. Owning a BEV or using a dynamic ridesharing service may be …
