Lack of access to good-paying jobs is one of the primary products of a largely inefficient Dallas transit system, according to a city of Dallas-commissioned study conducted by Shima Hamidi, director of The University of Texas at Arlington's Institute of Urban Studies, and her research team.
The study, which was presented to Dallas officials Monday, investigated how economic disparity and transportation are intertwined in Dallas.
This study found that more than 65 percent of residents living in the transit-dependent core of Dallas have access to less than 4 percent of regional jobs within a 45-minute transit and walking commute time. The study also showed more than 65 percent of residents in the transit-dependent core have to spend at least 1.5 hours commuting per day by transit to gain access to less than 4 percent of jobs if they want to or have to take transit.
The study showed that Dallas Area Rapid Transit ranks 23rd of 39 large- and medium-sized transit agencies in the nation in terms of the bus passenger miles per capita and passenger trips per capita. The city and the DFW region are facing transportation equity challenges when it comes into the transportation, according to the study. Hamidi says this has contributed to the increased poverty rate in Dallas, which has increased by 22 percent since 2000, while the total population increased by about 9.7 percent.
"The city of Dallas could experience an even higher concentration of poverty if transportation practices remain the same," said Hamidi, who also is a UTA urban planning assistant professor in the College of Architecture, Planning and Public Affairs. "From the planning perspective, these trends would cause the city to be more spatially segregated, especially in economic terms, and consequently the city could experience even more isolation of areas with poverty concentration."
Theresa O'Donnell, chief resilience officer for the city of Dallas, said the study will help Dallas build a better transportation system that helps more transit-dependent residents.
"Transportation Equity is one of the four discovery areas of the 100 Resilient Cities initiated by Rockefeller Foundation in Dallas," O'Donnell said. "Learning from Dr. Hamidi's study and incorporating its recommendations can improve quality of life for Dallas' residents in low- and moderate-income neighborhoods, allowing them access to more jobs, economic opportunities as well as cultural events, parks, retail hubs and health-care facilities."
Hamidi said that identifying transit-dependent populations is the first step in addressing these transportation challenges.
"Quantifying and identifying Dallas' transit-dependent core, and where the majority of transit-dependent population lives compared with where employment centers are critical to better understanding potential spatial mismatches for disadvantaged groups of population," Hamidi said.
Hamidi's study identified a hot spot core, largely in the southern part of the city, that is transit dependent. The results of hot spot analysis can be used to understand transit demand catchment areas within cities and regions. Transit demand catchment areas can be defined as the core location of transit riders with a high density of transit-dependent population.
The study also quantified and measured various performance components of transit system. Here is a summary of the findings:
