Environmental Justice Implications of Roadway Topography

July 5, 2021
Project ID: CTEDD 019-09
Author(s): Franklin Gbologah, Georgia Institute of Technology
Co-Author(s): Michael Rogers, Georgia Institute of Technology
CTEDD Grant Cycle: 2019 General RFP
Automobile emissions from highways are known to have harmful effects on the public. These harmful effects also raise concerns of environmental justice because their severity is highest near the transportation network. Established methodologies used in regional planning to identify the critical extent of emission dispersal from the highway and also to demarcate the boundaries of population group that is most at risk uses a fixed distance buffer analysis.

Where to? Origins and Destinations of TNC and Transit Trips Based on Mobile Devices

July 5, 2021
Project ID: CTEDD 019-11

Co-Author(s): Sean Barbeau, University of South Florida
CTEDD Grant Cycle: 2019 General RFP
Over the past decade, the rapid development and adoption of mobile computing and telecommunications technology has begun to disrupt established business models based on providing mobility services that were previously available primarily through the public sector (particularly public transit agencies) or that were privately provided through households’ and firms’ directly-owned and operated vehicles. Transportation has entered an era of immense change, with many transportation network companies (TNCs) both complementing and competing with public transit.

Transportation Equity Scorecard: A Tool for Project Screening and Prioritization

July 5, 2021
Project ID: CTEDD 019-12
Author(s): Kristine Williams, University of South Florida
Co-Author(s): Jeff Kramer, University of South Florida; Yaye Keita, University of South Florida
CTEDD Grant Cycle: 2019 General RFP
Despite disparity in methods and efforts, many Metropolitan Planning Organizations (MPOs) are seeking to incorporate equity in their planning and project prioritization processes. Yet MPOs often focus on avoiding adverse and disproportionate impacts of projects on traditionally underserved communities, without an equal focus on developing projects that advance the needs of these communities. In addition, although the economic benefits of projects are a key priority to MPOs in the project prioritization process, few MPOs screen and rank projects based on whether they specifically improve access to opportunity for low income and minority communities.

Embracing Emerging Internet-Based Traffic Big Data In Smart City Applications To Improve Transportation Systems Efficiency, Safety, And Equity

December 3, 2020
Project ID: CTEDD 021-07
Author(s): Taylor Li, University of Texas at Arlington
Co-Author(s): Qisheng Pan, University of Texas at Arlington
CTEDD Grant Cycle: 2021 General RFP
Minority and lower-income populations have historically been disproportionately underrepresented in STEAM education and jobs. The educational attainment gap for underrepresented minorities graduating high school and earning a college degree, especially in the STEM field, continues to remain wide. Teaching theories of environmental justice and transportation planning in a school curriculum helps to empower the youth of communities by addressing local issues concerning transportation plans and environmental justice and ultimately, helps students to develop skills to make important life and career decisions.

Creating A Situation-Aware Sensing Environment For Cyclists: An Innovative And Cost-Effective Smartphone-Based Approach

December 3, 2020
Project ID: CTEDD 021-08
Author(s): Shuchisnigdha Deb, University of Texas at Arlington
Co-Author(s): Ming Li, University of Texas at Arlington
CTEDD Grant Cycle: 2021 General RFP
This research will assess the feasibility and effectiveness of a Biker Assistance System (BAS) in different roadway contexts using a prototype mobile application. The application would make use of smartphones’ onboard speakers and microphones to monitor potential hazards and help bicyclists avoid crashes.
