Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang Jan 2019

Webinar: Modeling Freeway Traffic In A Mixed Environment: Connected And Human-Driven Vehicles, Xianfeng Terry Yang

TREC Webinar Series

Although connected vehicles (CVs) will soon go beyond testbeds, CVs and human-driven vehicles (HVs) will co-exist over a long period. Hence, it is critical to consider the interactions between these two types of vehicles in traffic flow modeling. In this study, we aim to develop a macroscopic model to understand how CVs would impact HVs in the traffic stream. Grounded on the second-order traffic flow model, we study the relationships among flow, density, and speed by two sets of formulations for the groups of CVs and HVs, respectively. A set of friction factors, which indicate CVs' impact to HVs, are ...


Webinar: Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri Oct 2018

Webinar: Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri

TREC Webinar Series

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

This session will walk you through the steps to plan a unique engagement approach for each project and share examples of what can happen when these tools are used correctly and what can go wrong when they are ...


A Survey Of Ride-Hailing Passengers, Steven Gehrke May 2018

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 ...

Defining Place: A Review Of How Place Type Is Measured And Constructed, Kelly Rodgers

TREC Friday Seminar Series

Part of the Student Presentations from TRB

Researchers have been parsing which components of the built environment contribute to outcomes of interest and to what degree, particularly the effects on vehicle use and walking. Increasingly, researchers and practitioners recognize that the type of neighborhood may affect individual travel behaviors. These bundle of various land use and transportation system characteristics can be constructed as different neighborhood or place types. But not all place types are constructed with the same use, purpose, or methods. This presentation will review three classifications of place typologies to better understand their purpose and appropriate application as ...

Development Of A Multi-Modal Travel Demand Module For The Regional Strategic Planning Model, Huajie Yang Jan 2018

Development Of A Multi-Modal Travel Demand Module For The Regional Strategic Planning Model, Huajie Yang

TREC Friday Seminar Series

Part of the Student Presentations from TRB

Integrated land use and transportation models have evolved along a spectrum with simplistic sketch planning models on one end and sophisticated microsimulation models on the other. While each type of these models has its niche, they are largely unable to balance the flexibility and realism of microsimulation and the speed and interactiveness of simple models. The Regional Strategic Planning Model (RSPM) aims to fill this gap by taking a microsimulation approach but making other simplifications, to model first-order long-term outcomes of land use and transportation quickly. It takes into consideration the underlying uncertainties ...


Exploring Bicycle Accessibility And Equity In Portland, Oregon, Jenny H. Liu Jan 2018

Exploring Bicycle Accessibility And Equity In Portland, Oregon, Jenny H. Liu

TREC Friday Seminar Series

As urban areas across the country are investing in bicycle and pedestrian infrastructure to promote environmentally sustainable transportation and to develop livable communities, many have pointed to improvements in environmental quality, economic development and public health as potential positive outcomes. While these outcomes of active transportation infrastructure are relatively well documented, it is also known that both transportation and environmental amenities are typically unevenly distributed in the urban context. Studies show that those who are the most socioeconomically disadvantaged (i.e. low income, people of color, etc.) are also those who disproportionately experience transportation disadvantages.

This study contributes to the ...

Webinar: The Effects Of Demand-Responsive Parking On Transit Usage And Congestion: Evidence From Sfpark, Nicole Ngo Sep 2017

Webinar: The Effects Of Demand-Responsive Parking On Transit Usage And Congestion: Evidence From Sfpark, Nicole Ngo

TREC Webinar Series

Parking is a serious issue in many urban areas, especially those experiencing rapid population growth. To address this problem, some cities have implemented demand-responsive pricing programs, where parking prices vary depending on the occupancy rate in a previous period. Yet, few empirical studies have rigorously evaluated these programs. In this study, we investigate the impacts of SFpark, a demand-responsive pricing parking program in San Francisco that began in 2011. We observe effects on three important aspects of urban transportation: parking availability, transit bus ridership and congestion. The timing of this program is plausibly exogenous to factors that affect these outcomes ...


Webinar: Breaking Barriers To Bike Share: Insights On Equity, Nathan Mcneil, Jennifer Dill, John Macarthur Aug 2017

Webinar: Breaking Barriers To Bike Share: Insights On Equity, Nathan Mcneil, Jennifer Dill, John Macarthur

TREC Webinar Series

While the number of public bike share systems in the United States grew considerably in recent years, early evidence indicated that many systems were not serving the diverse populations of cities, particularly lower-income residents and people of color. Lack of bike share stations in neighborhoods with people of color and/or lower incomes is one factor; however, considerable disparities appear to persist even when stations are placed in these communities.

Efforts to overcome access and use barriers (such as cost, payment options, and familiarity with the system) to bike share for underserved communities have been initiated in a number of ...
