Deadhead Minimization with a Flexible Facility Locator Tool

Originally written for Dr. Kari Watkins’ Transit Systems Planning and Design course, we designed a Shiny program to compare bus deadhead time between existing and potential depot locations. The concept arose from MARTA’s interest in a north-metro bus depot and our desire to produce a result that will continue to be meaningful in the future.

The poster was presented at the Transportation Research Board’s 2021 virtual conference and the paper was published in the Transportation Research Record. The facility locator tool is available on GitHub. The tool uses the dodgr package for network analysis and input GTFS data.

I presented this work at the joint GPA/TAPA conference in Chattanooga, TN on October 7, 2021.

localcovid19now: processing and mapping COVID-19 case data at subnational scales

Following my work in the Friendly Cities Lab, we’ve written an article on the localcovid19now package we developed. The paper discusses how the package aggregates data from sources across the world and allows case counts and event risk levels to be easily used and visualized.

Counteracting COVID-19 Risk Misestimation with an Interactive Website: An Online Informational Intervention

It’s been really wonderful to work on the COVID-19 Event Risk Planning Tool, and particularly interesting to collaborate with Allie Sinclair and other researchers at Duke University’s Department of Psychology and Neuroscience to understand how people have been using the website and where it is effective. Very exciting to see user interaction in context beyond the site’s analytics!

Autism Services Map

As a graduate research assistant for Dr. Singh at Georgia Tech, I used R Shiny and MySQL to create an interactive map of autism services in Georgia. It’s intended to provide an interface for autistic people, caregivers, and care providers to find services and providers that meet their needs. It also serves as an educational and research tool, allowing users to view available services throughout the state and spatially compare them to elements of the CDC/ATSDR Social Vulnerability Index. I also designed the homepage and the shiny wrapper for the Service Cliff Visualization.

The project is currently in Version 1 and is planning to enter testing in clinics in summer 2021. Next steps include further work with focus groups, integrating more data, and quality of life improvements.

Covington Corridors Studio

I worked with Aaron Fortner and fellow MCRP students to produce a corridor-focused plan for Covington, GA. I led the Washington Street Road Diet Big Idea component, focusing on improving Washington Street’s walkability, creating a gateway to Covington, and connecting affordable housing with greenspace and the downtown.

Austin, Tex. Next Generation TAMP

My group produced this Transportation Asset Management Plan for Austin, Tex. in Dr. Adjo Amekudzi-Kennedy’s Infrastructure Systems course. The plan discusses vulnerabilities to Imagine Austin Corridors from the urban heat island effect, flooding, and wildfires with a focus on equity and filling gaps from existing asset management plans.

Semester Design Project for CEE 4600: Transportation Planning and Design

I do not have an engineering background, rather a mathematics bachelor’s, so I needed to take Transportation Planning and Design as a pre-requisite for graduate-level transportation systems engineering courses.

For the semester project, we designed a new road to fit parameters given to our lab group. Our design features new intersections analyzed in Synchro, horizontal and vertical curvature, cross sections, and MUTCD marking and signage. I am particularly interested in active transportation planning, so I surpassed the project requirements for shared-use path designs.
