Nice! Once upon a time I did something very similar.

AFAICT the only reliable source of commute and transit times is Google Maps. To be useful it requires real traffic data. Unfortunately Google jacked up the prices way too high to be useful.

My dream is a service for building isochrone maps with full support for walking/biking/transit/driving.

I used the walkshed map (also supports bike, car, and transit) to decide which part of the city to live in.

Google doesn't generate traffic data for public transit services; they buy it from the agencies that run those services. You can go directly to them for it.
