🧹 Chore: Remove capacity constraint on PM dummy PNR routes

[i-am-sijia]

In the BART transit implementation, EA, MD, EV PNR dummy routes have unlimited capacities. AM and PM PNR dummy routes are subject to capacities in the pnr-access direction.

See relevant code in Lasso:

• Reading the input pnr_station.csv
• Creating vehicle tables for PNRs
• Creating PNR trips with associated vehicles
• Appending PNR vehicles to the model vehicles

During transit assignment in tm2py, EA PNR boardings affects AM. The AM PNR dummy routes’ headways are adjusted based on the EA PNR boardings, and if EA PNR boardings exceeds the AM parking capacity, the AM headway will be set to 999. So essentially we are constraining the EA + AM boardings to AM capacities. See the relevant code here.

We want to also set unlimited capacities for PM PNR dummy routes, it is probably just update the few lines in Lasso as pointed out above.

Progress:

• Sufficiently defined
• Approach decided
• Implemented
