Kathryn (Katie) Tyler is a second year master’s student whose research focuses on addressing gaps in public transit service. More specifically, she is examining bus networks in four US cities using GIS multi-criteria suitability modelling. Her research is largely motivated by the positive climate and social benefits of public transit. Public transportation has the potential to drastically reduce greenhouse gas emissions and alleviate negative public health outcomes associated with current transportation systems which are dominated by passenger cars and highway driving. Additionally, with increasing competition from ridesharing, inadequate infrastructure investments, and uncertainty surrounding COVID-19’s effects on public transit, it is critical to study how public transportation services can be improved.

The four cities that Katie’s research focuses on - Denver, Austin, Las Vegas, and Sacramento - are all experiencing high rates of population growth and were selected because of their similar population size and demographic characteristics, with differing levels of bus service. These places are experiencing patterns of growth similar to many other American cities such as Orlando, Charlotte, Portland, and Columbus where this research may also be applicable. In the face of nationwide bus ridership decline, cities that have redesigned their bus networks have been able to retain or increase ridership as a result of improved service.

Katie’s research uses GIS to perform multi-criteria modelling, making it easy to establish the relative importance of multiple criteria such as population density, job density, business locations, and transport-vulnerable populations. This research will provide a comprehensive comparison between two specific multi-criteria modelling methods: Boolean overlay and Analytical Hierarchy Processing (AHP). Few research articles compare different suitability modeling methods side by side. The ultimate goal of these models is to identify high priority areas for expanded bus service and to identify bus stops that may have a mismatch between their service frequency and the need for service at that location.

Katie recently received the GIS in the Rockies (GISITR) scholarship award for her research. This award is given to a student in the Rocky Mountain region (Idaho, Montana, Wyoming, Nevada, Utah, Colorado, Arizona, and New Mexico) for original and promising geospatial research. She accepted the award and presented her research at the virtual GIS in the Rockies conference this past September.

Katie Tyler Wins GIS in the Rockies Competition Anonymous (not verified) Thu, 09/23/2021 - 15:42

Katie Tyler won a GIS in the Rockies (GISITR) competition for the most promising graduate student enrolled in a university or college in the Rocky Mountain region (Idaho, Montana, Wyoming, Nevada, Utah, Colorado, Arizona and New Mexico) for a portion of her Masters thesis research "Systematic Criteria Selection for Suitability Modeling of Public Transportation in Denver Colorado". She will present this research this week at the upcoming GISITR 2021 conference (virtual), and receive a $1,000 award.

GIS in the Rockies is the Rocky Mountain West’s premier geospatial information and technology conference. The conference offers opportunities for industry professionals to learn more about geospatial technology issues and business-centric strategies supporting every vertical market touched by the geospatial industry. Historically, attendees have included representatives from local, state, and federal government, the utilities industry, environmental services, land surveying professionals, the oil and gas industry, students, educational practitioners, and retail and business marketing professionals. Whether you are a seasoned GIS professional or are new to the industry, GIS in the Rockies Conference will offer industry insights and opportunities for everyone.

GIS in the Rockies offers pre-conference workshops related to important topics in the GIS industry. There are a limited number of openings for each workshop, so it is best to sign up for a workshop during the registration process. If you have already registered for the conference, you can modify your existing registration to add a workshop.

The GIS in the Rockies Planning Committee organizes the conference. The planning committee generally consists of volunteer GIS professionals who currently work in the industry — although the committee is not limited to GIS professionals. If you are interested in joining the planning committee or have questions about the committee, please contact them.
