Research Question

Single sentence description: Combine PeMS aggregated station-daytype tables with SHN postmile segments using the station-to-postmile crosswalk and make exploratory maps.

• Epic - PeMS Roadmap #1139

Detailed description:

• With tabular PeMS data, it was hard to see where the stations are located, since charts using postmiles as the x-axis isn't intuitive to grasp
• Earlier PR made a crosswalk linking PeMS stations to particular SHN postmiles. Let's see how it all comes together.
• Identify missing gaps (are there highways missing that we should have, etc)

Data sources

• Cal-ITP data sources:
• station_daytype_hour - PeMs stations aggregated to hour / weekday + weekend
• state_highway_network_postmile_segments: line segments of SHN
• crosswalk linking stations to SHN postmiles
