Update #2

I've found the pedestrian, bike and motor vehicle congestion information we need to make this a truly useful tool here:

Data dumps are limited to 500 records so I have reached out to get a full dump of this information.

Cross walk update: Every intersection is considered a cross walk so other than analyzing aerial photos there doesn't appear to be a way to get this information.

An aside, after talking with the streets department, cross walk data might not be necessary as the city has made great efforts to ensure traffic control devices show vehicles and pedestrians when it's safe to cross. Painting the cross walk doesn't significantly increase safety beyond those efforts from what I understand. It's important to teach our kids how to safely cross roads, rather than to rely on drivers and white lines.

Update #1

I'm working on getting data for traffic control devices and cross walks as well as motor vehicle collisions.

Some of the challenges are that PennDOT isn't responsible for this data because Philadelphia is a first class city.

We have an "impervious surface" dataset which should help us find out where elevated foot paths and sidewalks are, however, I don't think that data includes cross-walks.

It's possible that we can launch an effort to mark cross-walks by hand using aerial photography and also classify how busy a street is.

I estimate that task being a minimum of 700 man hours of analyzing the aerial data.
