Connected Streetcar Project

The long-term vision and promise of Connected Vehicle (CV) technology is to use communications between vehicles and between vehicles and infrastructure to improve the safety and efficiency of our transportation network. This project will deploy the Multi Modal Intelligent Traffic Signal System (MMITSS) — a Dynamic Mobility Application, developed at the University of Arizona through a Connected Vehicle Pooled Fund Project — on the Portland Streetcar and at four intersections along the “Art Museum Corridor” in Southwest Portland. Through this deployment, the project will create a foundation (experience, understanding) for deploying connected vehicle infrastructure in the City and facilitating connected vehicle research in the NITC UTC.

Objective: Create a foundation for deploying connected vehicle infrastructure and facilitating connected vehicle research within the NITC UTC.

CV hardware (OBU and RSU) with MMITSS (Multi-Modal Intelligent Traffic Signal Systems) will be installed on two (2) Portland Streetcars and four (4) signal cabinets in the “Art Museum Corridor” located between SW 10th/Alder & SW 10th /Clay for 9 months beginning in early 2019.

Potential Benefits to Streetcar & City:

Streetcar has established goals around system performance

  • 85% on-time performance
  • Less than .65 collisions per 1000 hours of service
  • Goal of this project: evaluate if a more extensive deployment of this technology could help improve streetcar system performance

Project is intended to lay a foundation for CV deployment and research in Portland. Potential future work:

  • Expanded deployments within the Portland region – streetcar or light rail
  • Identification of multimodal CV application opportunities including pedestrians and bicyclists
  • Research in integration of bicycles and pedestrians into the CV environment
  • Development of (additional) visual analytics and data processing paradigms for CV data
