Data

The last decade has witnessed an unprecedented convergence of communication, control, and sensing that can potentially transform transportation infrastructure and delivery. At the most basic level, efficient operation and maintenance of our nation’s transportation infrastructure requires real time data exchange provided by intelligent transportation system technology. When implemented, these technologies have the potential to revolutionize the nation’s economic vitality by moving people and goods more quickly, efficiently, safely, and at lower cost to consumers.

In Brazil, the recent explosion of informal transport activity is having profound effects on formal, regulated transport systems and is the source of great controversy in the urban passenger transportation arena. A variety of policies are being proposed to manage what has been an uncontrolled growth of the sector. This study seeks to understand the advantages these systems have for users who choose them, and how proposed policies will impact these benefits. A corridor in Rio de Janeiro with substantial informal activity was used as a case study and field trips were made to gather basic...

Transit stops serve as crucial components of journeys for riders, but their condition is often left out of equity considerations. Two important empirical questions are what stop amenities, such as places to sit, clear sign age, shelters for inclement weather, and unobstructed curbs are present, and how are they distributed across systems, which may reveal neighborhood or route-specific disparities.

In addition to prohibiting discrimination, it is imperative to ensure shared mobility is accessible to all. Equitable treatment of shared mobility providers (e.g., data, insurance, licensing) is also a key consideration.
