Project: #176 Mesoscopic car-truck flow modeling and simulation: theory and applications Progress Report - Reporting Period Ending: Sept. 30, 2018 Principal Investigator: Sean Qian Status: Active Start Date: Aug. 7, 2018 End Date: June 30, 2019 Research Type: Applied Grant Type: Research Grant Program: FAST Act - Mobility National (2016 - 2022) Grant Cycle: 2018 Mobility21 UTC Progress Report (Last Updated: Sept. 23, 2018, 7:35 p.m.) % Project Completed to Date: 50 % Grant Award Expended: 50 % Match Expended & Document: 50 USDOT Requirements Accomplishments 1. Estimated the dynamic origin-destination (OD) demand of private cars and trucks using traffic counts and speed data. 2 We developed bi-modal traffic flow model, and integrated it in traffic simulation models for large-scale networks 3. We developed the traffic simulation models for the Pittsburgh region, which supports decision making for traffic management and planning. Impacts 1. have great promise to help SPC evaluate the regional impact of traffic improvement projects 2. presented the work in meetings with PennDOT, the City of Pittsburgh, McKees Rocks. 3. Helped McKees Rocks to plan for traffic mitigation under the new CSX terminal Other A large-scale network simulation models that encapsulates evolution of cars and trucks, as well as the respective software package A report that summarizes all findings from the case study of McKees Rocks Outcomes New Partners Federal Highway Administration Issues N/A
