There is an active debate about the potential costs and benefits of emerging “smart mobility” systems, especially in how they will serve communities already facing transportation challenges. This paper describes the results of an assessment of these equity issues in the context of lower-income areas of Portland, Oregon, based on a mixture of quantitative and qualitative research. The study found that by lowering costs and improving service for public transit, ridesharing and active transportation, smart mobility systems could address many of the needs of transportation disadvantaged communities. Similar to those found in other case studies, significant barriers prevent smart mobility …

This project focuses on a mode of transportation that is currently left out of V2X (vehicle-to-everything) conversations: bicycling. The project demonstrates how university researchers, city traffic engineers, and signal-controller manufacturers can come together to give bicyclists the same technology appearing on modern vehicles: Green Light Optimized Speed Advisory (GLOSA). GLOSA allows motorists to set their speed along corridors to maximize their chances of catching a “green wave” (i.e., not being forced to stop as they travel through the corridor). This project demonstrates how GLOSA can be used by bicyclists in the same way it is used by motorists on a …

The term “connected vehicle (CV)” refers to vehicles equipped with devices, which enable wireless communication betweeninternal and external entities, supporting vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I) and vehicle-to-everything (V2X)communications. The widespread deployment of CVs will address a range of transportation challenges related to safety, mobility,and sustainability. Recent research efforts on connected bicycles have focused on the uses and limitations of the state-of-the-arttechnologies, safety implications, the reliability of various communication modes, and consumer adoption. Existing researchfocuses on either technologies that utilize data received from sensors and the internet to govern devices attached to the bicycle(situational sensing) or two-way communication. While there has been …

TREC Final Reports
In recent years, the importance of travel time reliability has become equally important as average travel time. However, the majority focus of travel time research is average travel time or travel time reliability on freeways. In addition, the identification of specific factors (i.e., peak hours, nighttime hours, etc.) and their effects on average travel time and travel time variability are often unknown. The current study addresses these two issues through a travel time-based study on urban arterials. Using travel times collected via Bluetooth data, a series of analyses are conducted to understand factors affecting reliability metrics on urban arterials. Analyses …
