Exploring Data Fusion Techniques to Derive Bicycle Volumes on a Network

Sirisha Kothuri
Planners and decision makers have increasingly voiced a need for network-wide estimates of bicycling activity. Such volume estimates have for decades informed motorized planning and analysis but have only recently become feasible for non-motorized tr ... Read More

Road User Understanding of Bicycle Signal Faces on Traffic Signals

Christopher Monsere
Sirisha Kothuri
Bicycling is increasing in the United States – the number of trips made by bicycle more than doubled from 1.7 billion trips in 2001 to 4 billion in 2009 (NHTS, 2009). With the increase in bicycling rates, there is a critical need for cycling infras ... Read More

Land Use and Transportation Policies for a Sustainable Future with Autonomous Vehicles: Scenario Analysis with Simulations

Liming Wang
Yao-Jan Wu
Even though there are tremendous uncertainties in the timing and evolution path of the Autonomous Vehicles (AV) technology, it may become a likely reality within most MPOs' long-range regional transportation plan horizon of twenty years. Yet a recent ... Read More

Connected Streetcar Project

Kristin Tufte
Larry Head , John MacArthur
This project will create a foundation for deploying connected vehicle infrastructure and facilitating connected vehicle research for the NITC UTC. Connected Vehicle (CV) technology and the associated data has the potential to help us better understan ... Read More

An Electric Bus Deployment Framework for Improved Air Quality and Transit Operational Efficiency

Xiaoyue Liu
Aaron Golub , Ran Wei
Public transit, compared with passenger cars, can effectively help conserve energy, reduce air pollution, and optimize flow on roadways. In recent years, Battery Electric Bus (BEB) is receiving an increasing amount of attention from transit vehicle i ... Read More

Revisiting TODs: How Subsequent Development Affects the Travel Behavior of Residents in Existing Transit-Oriented Developments

Nathan McNeil
Jennifer Dill
Portland State University has worked with the Portland Metro regional government periodically since 2005 to survey occupants of buildings for which developers had received funding from Metro’s Transit-Oriented Development (TOD) Program. The TOD pro ... Read More

Improving Integration of Transit Operations and Bicycle Infrastructure at the Stop Level

Miguel Figliozzi
The interaction between transit vehicles and bicycles can create conflict when both share the same space. In particular, the location of transit stops poses specific challenges along bicycle facilities. Little research exists to offer insight on how ... Read More

Access to Opportunities: Redefining Planning Methods and Measures for Disadvantaged Populations

Arlie Adkins
Stephen Mattingly
This project will be made up of two separate studies that together will investigate areas where transportation planning and engineering can better serve disadvantaged and underserved communities. An interdisciplinary team of planning and public healt ... Read More

Understanding Economic and Business Impacts of Street Improvements for Bicycle and Pedestrian Mobility - A Multi-City Multi-Approach Exploration [Phase 2]

Jenny Liu
Many cities across the country, as part of Complete Streets initiatives or to promote community livability and environmental sustainability, have engaged in street improvement or transportation infrastructure upgrade projects that increase access and ... Read More

Life-space mobility and aging in place

Ivis Garcia Zambrana
Alan DeLaTorre
Research on older adults explores the notion of “aging in place”—providing older adults the opportunity to continue to occupy familiar surroundings, to live in their own homes and communities. But oftentimes one’s ability to stay or leave, pa ... Read More

A Decentralized Network Consensus Control Approach for Urban Traffic Signal Optimization

Gerardo Lafferriere
We propose the development of a simulation tool to analyze the use of a mathematical consensus approach to manage the signal control on an urban street network. The underlying principle in a consensus approach is that traffic signal cycles are adjus ... Read More
