Abstract
The Asymmetric Cell Transmission Model (ACTM) is a widely accepted macroscopic model for freeway traffic. Essentially, the model is based on the original Cell Transmission Model (CTM), with modified merge equations in order to make it suitable for ramp metering optimization. However, an unfeasible merging behavior is observed when uncontrolled merges are simulated if using a simplistic but common calibration. A simple methodology for calibrating the two parameters involved in the ACTM merge mode...
Keywords
