transit vehicles on road segments?? #44

Open JabunchWork opened 8 months ago

JabunchWork commented 8 months ago

I was very glad that you have continued to update the python for transit gtfsfunctions tools I was wondering if you have ever thought about how to estimate the number of vehicles per hour by direction on road segments instead of stop to stop segments? This is something we are constantly asked to do. I can see two approaches.

1: somehow snap the stop to stop segments to a road network and then further cut them into smaller segments based upon the road network links.

2: add a layer of small polygons or cutlines located where ever you want the statistics, then use a geographic join and summarize the trips that cross each cutline by direction.

My python is not strong enough to do either though I can do the latter in QGIS.

thanks! yes, that's definitely an interesting problem to solve. Unfortunately, that's not part of the open source package right now as the solution we use for this right now involves some infrastructure investment.

I think I uploaded the gtfs in as an attachment but will check. It is from Harrisonburg Va.
