After a few weeks of commuting, here are a few tips I have.
1. Get a bike with platform pedals (or cage or whatever they're called) and wear your steel toe boots (or other appropriate footwear). Why haul the extra weight of an extra pair of shoes?
2. Don't assume anything. Don't try to get a jump on the light and start out before it turns green even if you know your turn is next. Today I was turning left and I was tempted to do this, but since I was on bike and not in my car, the sensor didn't pick me up so I didn't get the turn arrow. If I had went I'd have been out in the intersection when traffic going the other way got the green.
3. When riding at night conserve headlight battery power by switching off your head lamp when you are in sections that are well lit by street lights.
