Webinar: Radar Point Cloud Segmentation Using Gmm In Traffic Monitoring, Siyang Cao
TREC Webinar Series
Intelligent transportation systems (ITS) change our communities by improving the safety and convenience of people’s daily mobility. The system relies on multimodal traffic monitoring, that needs to provide reliable, efficient and detailed traffic information for traffic safety and planning. How to reliably and intelligently monitor intersection traffic with multimodal information is one of the most critical topics in intelligent transportation research. In multimodal traffic monitoring, we gather traffic statistics for distinct transportation modes, such as pedestrians, cars and bicycles, in order to analyze and improve people’s daily mobility in terms of safety and convenience. In this study, we use a …
Webinar: The Impact Of Transportation-Related Barriers On Self-Perceived Physical Health Among Adults In The Us, Philip Baiden, Godfred Boateng
Webinar: The Impact Of Transportation-Related Barriers On Self-Perceived Physical Health Among Adults In The Us, Philip Baiden, Godfred Boateng
TREC Webinar Series
Drawing from the framework of social determinants of health, the objective of this study is to investigate the cross-sectional association between transportation-related factors and self-perceived physical health among adults in the U.S.
Data for this study were derived from the 2017 National Household Travel Survey. An analytic sample of 71,235 respondents aged 18 and 64 years was analyzed using binary logistic regression. Of the 71,235 respondents examined, 8.9% perceived their physical health to be poor. About 36% of the respondents had fewer vehicles per individuals in the household.
Controlling for the effects of other factors, respondents who had fewer vehicles …
Webinar: Data-Driven Mobility Strategies For Multimodal Transportation, Yao-Jan Wu, Abolfazl Karimpour, Xianfeng Terry Yang
Webinar: Data-Driven Mobility Strategies For Multimodal Transportation, Yao-Jan Wu, Abolfazl Karimpour, Xianfeng Terry Yang
TREC Webinar Series
Multimodal transportation systems (e.g., walking, cycling, automobile, public transit, etc.) are effective in increasing people’s travel flexibility, reducing congestion, and improving safety. Therefore, it is critical to understand what factors would affect people’s mode choices. With advanced technology, such as connected and automated vehicles, cities are now facing a transition from traditional urban planning to developing smart cities. To support multimodal transportation management, this study serves as a bridge to connect speed management strategies of conventional corridors to connected vehicle corridors.
The study consists of three main components. In the first component, the impact of speed management strategies along traditional …
Webinar: The Impact Of Ride Hail Services On The Accessibility Of Nonprofit Services, Dyana Mason
Webinar: The Impact Of Ride Hail Services On The Accessibility Of Nonprofit Services, Dyana Mason
TREC Webinar Series
Nonprofit organizations are responsible for providing human services across the United States, often in partnership with government agencies. In this work, they address some of the most pressing social issues – including homelessness, poverty, health care and education. While many of these organizations consider location and accessibility crucial to supporting their clients – often locating services near bus or train stops, for example – little is known about the impact of new technologies, including ride hail services (also called Transportation Network Companies, or TNCs) like Lyft and Uber, on nonprofit accessibility. Do these services help fill gaps in client needs? …
Webinar: Electric Bus Deployment: Cost And Environmental Equity, Cathy Liu
Webinar: Electric Bus Deployment: Cost And Environmental Equity, Cathy Liu
TREC Webinar Series
This presentation introduces an innovative spatiotemporal analytical framework and web-based visualization platform developed by researchers at the University of Utah to assist transit agencies in identifying optimal deployment strategies for a battery-electric bus (BEB) system by using a combination of mathematical programming methods, GIS-based analysis, and multi-objective optimization techniques. The framework allows transit agencies to optimally phase in BEB infrastructure and deploy the BEB system in a way that can minimize the capital and operational cost of the BEB system while maximizing its environmental benefits (i.e., emission reduction).
Webinar: Eliminating Cash Options For Public Transit Fares: Costs, Benefits And Equity Impacts, Aaron Golub
Webinar: Eliminating Cash Options For Public Transit Fares: Costs, Benefits And Equity Impacts, Aaron Golub
TREC Webinar Series
Many transit agencies plan to automate their fare collection and limit the use of cash, with the goals of improving boarding and data collection while lowering operating costs. Yet about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone. This webinar will present part of a larger research project exploring these issues in the cities of Denver, Colorado, and Eugene and Portland–Gresham, Oregon. In this part, we explore the tradeoffs between reducing cash acceptance, ridership and the …

Webinar: Rethinking Streets During Covid, Clare Haley, John Larson-Friend, Marc Schlossberg, Aliza Whalen
TREC Webinar Series
Re-allocating space on streets to accommodate new uses – particularly for walking, biking, and being – is not new. However, COVID-era needs have accelerated the process that many communities use to make such street transitions. Many communities quickly understood that the street is actually a public place and a public good that serves broader public needs more urgent than the free flow or the storage of private vehicles. This seminar describes a new case study book that captures some of these quick changes to city streets in response to societal needs during COVID, with two open questions: 1. What changes …
Webinar: Transit Impacts On Jobs, People And Real Estate, Arthur C. Nelson, Kristina Currans, Robert Hibberd
Webinar: Transit Impacts On Jobs, People And Real Estate, Arthur C. Nelson, Kristina Currans, Robert Hibberd
TREC Webinar Series
This webinar has six elements: Introducing themes related to how transit should affect the location of jobs and people, and how real estate should respond; Creating a research typology of different landscapes served by transit that is also useful in transit planning; Analyzing how transit stations influence shifts in the regional share of jobs, people and housing; Investigating how transit station proximity influences mode choice and household transportation budgets; Estimating the effect of transit station proximity on real estate rents by type of transit system and type of real estate, and the extent to which outcomes are consistent with theory; …

Webinar: Land Use And Transportation Policies For A Sustainable Future, Liming Wang
TREC Webinar Series
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 survey of the largest MPOs in the US indicates only one of them "even mentions driverless, automated, or autonomous vehicles in its most recent RTP". One of the uncertainties in assessing the impacts of AV is their direction: on one hand, self-driving cars could increase VMT by increasing roadway capacity, lowering costs of travel; on the other, they may reduce VMT by …
Webinar: Transportation Benefits Of Polycentric Urban Form, Reid Ewing, Sadegh Sabouri
Webinar: Transportation Benefits Of Polycentric Urban Form, Reid Ewing, Sadegh Sabouri
TREC Webinar Series
A “polycentric” region consists of a network of compact developments connected with each other through high-quality transportation options. Rather than continuing the expanse of low-density development radiating from an urban core, investments can be concentrated on central nodes and transit connections. This development pattern is very popular in Europe and is linked to significant benefits. This presentation is aimed at exploring the academic literature and empirical evidence surrounding polycentric development, analyzing more than 120 regional transportation plans to see how they promote polycentric development, defining types of centers in a hierarchy of centers, quantifying the transportation benefits of polycentric development, …
