1. A computer-implemented method comprising:
defining, by a processing device, a plurality of parameters so that any orthogonal intersection can be described;
building, by the processing device, an orthogonal parameterized model that can represent any orthogonal intersection based at least in part on the plurality of parameters that can describe any intersection of interest;
expanding, by the processing device, the orthogonal parameterized model to generate a fully parameterized intersection model that accounts for intersection complexities including accounting for a total lateral distance from a stop bar associated with the vehicle to a center left target line in meters and a total longitudinal distance from the stop bar associated with the vehicle to the center left target line in meters; and
building, by the processing device, a low-fidelity analytical that computes various metrics based on the fully parameterized intersection model.
