Research Highlights

Evaluating Improved Transit Connections for Ladders of Opportunity

Stephen Mattingly Yi-Chang Chiu , Sia Ardekani , Courtney Cronley , Noelle Fields
Many transit operators employ limited strategies to provide connectivity to transit, like bicycle racks on buses. This project will examine more innovative options, such as: subsidies, hybrid ride sharing business models, flexible routing, smaller transit vehicles, transit-sponsored bike share programs, and social carpooling to meet first and last mile needs and increase mobility for all users, especially underserved and disadvantaged populations.

Today, our cities face various challenges, including urban sprawl, air pollution, and obesity. To address some of these problems, cities and local governments consider land use planning and urban design to lower car dependency and promote walking and biking. Many studies have characterized the built environment in terms of D variables density,… Read More
