Summary

- Objective: Calibrate VOYAGER for two-lane roundabouts using PARAMICS as a benchmark.
- Methodology:
- Modeled a four-arm, two-lane roundabout in both PARAMICS and VOYAGER.
- Used PARAMICS delays as target for VOYAGER calibration.
- Tested VOYAGER's Gap Acceptance (HCM) and Empirical algorithms.
- Varied VOYAGER parameters to match PARAMICS delays.
- Findings (Scenario A):
- Gap Acceptance: Critical Gap = 4.2s, Follow-up Time = 1.4s.
- Empirical: Capacity Slope = 1.1, Capacity Intercept = 2100.
- Results (Scenario A):
- VOYAGER delays matched PARAMICS delays using the above parameters.
