I Agree with Rando. Tempe is pretty safe and friendly towards cyclists. I changed my commute to take me through Tempe even though it was a longer route than my previous one that went through Mesa (not cyclist friendly) for safety concerns. I've managed to find an 11-mile route that takes me mostly through residential areas with bike lanes or along a canal. Both of which are very safe. Unfortunately, I have to go through 11 busy intersections. At that point I ignore traffic lights and assume everyone has a green light.
