Development Notes

Spatial Analysis Needs for RTP
The spatial analysis below will be run on the 2035 and 2050 final networks. For initial development, we will use Scenario 2b for 2050.

All scripts should be stored in the following repository: https://github.com/psrc/rtp-spatial-analysis

Intersection of transit stops and future density

Analysis assumptions
⦁ 1/4 and 1/2 mile circles
⦁ simple intersect, either in or not
⦁ by transit route type (Local, All-Day, Frequent, BRT and HCT)
⦁ number of people and jobs that are in supportive densities with service and in those in supportive densities without service (Gap)

Spatial Layers:
⦁ C:\Users\username\Puget Sound Regional Council\GIS - Sharing\Projects\Transportation\RTP_2026\transit\Transit_Network_2050_Scenario2b.gdb (stops layer)
