How to join field of a feature to another based on location?

[JamesDuBois]

Sorry, I don't know how to title this correctly....

I have a shapefile of TAZs as well as a shapefile of existing bike network and one of transit stops. I already have the length in miles for each segment of bike lanes. For each TAZ, I am trying to create a field that shows the total length in miles of bike paths as well as the total amount of transit stops per TAZ. The only way I can think of doing this is doing it by each individual TAZ within the shapefile, which would take forever. Is there a better way??

Sounds like you want to run the spatial join tool in arctoolbox. This would join TAZ (what every that is) to you bike network and then you run a summary statistics tool summing length by TAZ ID.
