🚀 Feature: Move PeMS Conflation to tm2py

[DavidOry]

User Story

MTC wants to consolidate their travel modeling software into tm2py and leverage the tm2py infrastructure. In this case, we want to conflate PeMS counts to the roadway network.

Progress:

• Sufficiently defined
• Approach determined
• Tests developed
• User story satisfied
• Doc strings
• General documentation
• Passing tests

Resolution Ideas

This would be a logical tm2py utility. But perhaps one that should most likely moved as part of the move of Lasso functionality into tm2py. Right now, the bundle of travel modeling Python code is as follows:

• travel-model-two-networks: this is the code WSP used to create the travel model two networks. Much of the functionality has since been moved to the more general purpose open-source Ranch repository. Moving forward, an ideal solution would be to refactor Ranch to use the network-wrangler base classes more directly. Currently, the PeMS conflation is done in a notebook that lives in this repository.
• Lasso: this is a bundle of code that handles the messy translations from Network Wrangler standards to Emme standards. It now includes a number of capabilities that are integral to the functioning of tm2py and would more logically live in tm2py

Risk

Not if it's a utility written as a stand-alone method.

Tests

A number of examinations should be done to ensure conflation is working as expected in challenging locations, e.g., near interchanges, near ramps.
