RES2023-10: Identification of Simulation Calibration Parameters Using Urban Freeway Data

Tennessee Department of Transportation (TDOT) has started using microsimulation tool, PTV VISSIM, more frequently for in-house traffic analysis. Microsimulation tools allow robustness and reliability in traffic analysis compared to generalized approach in the Highway Capacity Manual (HCM). Current TDOT PTV VISSIM user manual use calibration parameters based on best practices obtained from manuals developed by other state DOTs, however, it is critical to determine various calibration parameters to develop calibrated models for local conditions which could provide reliable simulation results. Data-driven and Tennessee specific calibration parameter development would be beneficial in enhancing TDOT’s model development and reliability of microsimulation-based traffic analysis. State specific calibration parameters could provide a more accurate representation of actual traffic flow, and reliable traffic analysis results will assist traffic operational decision-making process by balancing needs and resources.
