    Cost/Benefit Analysis of Fuel-Efficient Speed Control Using Signal Phasing and Timing (SPaT) Data: Evaluation for Future Connected Corridor Deployment
    (Minnesota Department of Transportation, 2023-03) Levin, Michael W.; Sun, Zongxuan; Wang, Shi’an; Sun, Wenbo; He, Suiyi; Suh, Bohoon; Zhao, Gaonan; Margolis, Jacob; Zamanpour, Maziar
    The objective of this methodology is to refine the preliminary results from previous work (11% fuel savings for one vehicle, one intersection) to an entire corridor of SPaT signals, with different CV market penetration, and with driver awareness of fuel savings benefits. The research will proceed in three parts. First, several vehicles will be instrumented with DSRC receivers and GPS tracking to record SPaT data and the vehicle trajectories together. Offline, the project team will optimize the speed and powertrain control based on recorded SPaT data, using the recorded vehicle trajectories to identify the constraints of traffic flow. A living lab consisting of a GM car engine loaded by a transient hydrostatic dynamometer will be used to measure the fuel consumption with and without speed control. Second, the project team will conduct traffic flow simulations to study the impacts of higher market penetration on the overall fuel benefits, including the benefits to legacy vehicles which unintentionally use SPaT based speed controls by following CVs. Third, network models will be used to predict changes in route choices as drivers recognize the benefits of fuel savings in the route utility. The numerical predictions of fuel savings will be combined into cost/benefit analyses to inform MnDOT on the future deployment of SPaT on other corridors.

    Feasibility of an Electric Car-Sharing Service in a Suburban Environment: Team Best Practices
    (Resilient Communities Project (RCP), University of Minnesota, 2022) Bransky, Jacob; Cade, Jackson; Margolis, Jacob; Ziegler, Spencer
    This project was completed as part of a partnership between the City of Edina and the University of Minnesota’s Resilient Communities Project (http://www.rcp.umn.edu). Edina is committed to providing clean, abundant, equitable, and accessible transportation options to all who live, work, and travel through the community. Edina’s newly passed Climate Action Plan includes goals to reduce community-wide vehicle miles traveled by 7% by 2030, and increase battery electric vehicle utilization to 25% of community-wide rolling stock. The City is also committed to prioritizing low-income household transportation opportunities. Edina project lead Grace Hancock collaborated with a team of graduate students enrolled in Professor Frank Douma’s course, PA 5232/CEGE 5212: Transportation Planning, Policy, and Deployment, to review literature and case studies of electric car-sharing services in peer suburbs in Minnesota and elsewhere around the country and recommend best practices for implementing such a system in Edina. The students’ final report and PowerPoint presentation are available.
