Research Highlights

Data-Driven Optimization for E-Scooter System Design

Jianqiang Cheng
Are e-scooters just the first sign of a shared-mobility revolution? If they are, then researchers at the University of Arizona intend to make sure that the emerging transportation system has functional models on par with other modes of transportation. In 2018, approximately 100 U.S. cities had already launched shared e-scooter programs, accounting for 38.5 million trips. However, the models to manage e-scooter sharing are only recently being developed. In a project funded by the National… Read More

The use and influence of health indicators in transportation decision-making

Kelly Rodgers
As a social determinant of health, transportation significantly contributes to well-being through several pathways. Researchers and practitioners have called for health indicators as one way to integrate public health concerns into transportation decision-making. However, it is unclear how indicators are used and what their impact is on policy. This case study of five cities explored how health-related indicators are being used in municipal transportation plans, whether they are… Read More
