Webinar: Transportation Resources And Behaviors Among Older Immigrants And Migrants

PRESENTATION ARCHIVE

OVERVIEW

This presentation reports findings from a cross-sectional survey of older Vietnamese immigrants in the Dallas-Fort Worth, TX metroplex and members of a Hispanic senior center in Hartford, CT. In addition to providing a description of transportation resources and behavior, we present a method for assessing the geospatial "regular activity spaces" of older adults based on the frequency and locations of routine activities. We also present options for assessing the geospatial burden of providing rides to older adults using "ride-provision activity spaces," which entails the frequency and locations of activities for which rides are given. Finally, we discuss the association of transportation-related factors and companionship among members of the senior center in Hartford, CT. Implications for this research include land use policy, assessment for and allocation of public assistance for transportation for older adults, and transportation-related programs to address...

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...
