GBNRTC Demonstration Model¶
Model Operation¶
The GBNRTC model is a four-step model run using TransCAD. Because TransCAD is proprietary software, the core model itself is not distributed with TMIP-EMAT.
Model Scope Definition¶
The model exploratory scope is defined in a YAML text file. In this example, the scope is given by:
