Overcoming Barriers for the Wide-scale Adoption of Standardized Real-time Transit Information
Sean Barbeau
Real-time transit information has many benefits to transit riders and agencies, including shorter perceived and actual wait times, a lower learning curve for new riders, an increased feeling of safety, and increased ridership.

Toward Automating the Measurement of Urban Design Qualities Related to Walkability
S. Hassan Ameli
Streets are one of the most significant elements of urban spaces to accommodate public activity and provide access to numerous locations and services. 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,…
