Webinar: Collecting and Analyzing Pedestrian Behaviors at Intersections Using LiDAR Tracking Technologies

PRESENTATION ARCHIVE

OVERVIEW

The aim of this research is to investigate pedestrian behavior at signalized intersections using state-of-the-art LIDAR sensing technologies and to use this data, along with vehicular data, to develop a more effective multimodal signal control system.

In the presentation, the presenters will describe a novel method of collecting pedestrian crossing behaviors at signalized intersection, discuss the findings and implications of data analytics, and introduce a novel approach to dynamic flashing yellow arrow mechanisms to reduce the conflict between left turn vehicles and crossing pedestrians.

KEY LEARNING OUTCOMES

  • Understand the framework of LiDAR sensing solutions;
  • Understand how to collect pedestrian behaviors at intersections;
  • Understand how to provide new protection for crossing pedestrians with object-tracking technologies.

THE RESEARCH

This webinar is based on a study funded by the National Institute...

Webinar: When Growth Outpaces Infrastructure: A Community-Engaged Assessment of Transportation Gaps

PRESENTATION ARCHIVE

OVERVIEW

This study used a community-engaged interdisciplinary approach to assess the gaps between economic growth and transportation infrastructure development, and the impact of potential gaps on access to opportunities for environmental justice populations within North Central Texas, where population growth has increased over 100% since 2000.

The interdisciplinary team, comprised of social work and civil engineering researchers, in partnership with the regional homeless coalition, measured residents’ perspectives of:

  • the economic growth in the area over the past decade,
  • the extent to which transportation infrastructure has matched the economic growth, and
  • the implications for access to affordable quality housing, employment, quality public education, as well as engagement in cultural and social activities.

The team utilized a mixed-methods (focus groups and survey data), exploratory design to collect responses from a diverse sampling frame. The study results produced an infrastructure profile for the region, in which increased infrastructure from toll ways have...

Webinar: The Impact of Transportation-Related Barriers on Self-Perceived Physical Health among Adults in the US

PRESENTATION ARCHIVE

OVERVIEW

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 per individuals in the household were 1.27 times more likely to report poor self-perceived physical health when compared to their counterparts with more vehicles per individuals in the household (AOR=1.27, 95% CI=1.17-1...
