Just to riterate what's already been said upthread: train, practise, and develop your sprint, at least by doing it, if not in conjunction with specific training regimens both on the bike and in the gym, which help you build strength and power.

Given the type of bike, I think the most practical way to get through an intersection quickly will be:
- start in quite a low gear, something you'd climb hills in
- push off, stand on the pedals for a few strokes to get off the line
- then sit and quickly spin the revs up to pretty high, like 100 rpm or so
- quickly change up one gear, revs up, change up, revs, etc.
Basic idea is using leg speed, high rpm and lower gear, instead of using leg power, low rpm, and higher gear. Like accelerating a manual shift car, you start in a low gear, keep the motor at a high rpm, and flick through the gears. OP will probably be through the intersection by the second gear change.
Reason? This is a city-type bike with upright position, high and swept back bars, platform pedals, step through frame. It isn't designed for the rider to apply big power like on a sprint. You can't get the right body position, pull down hard on the bars, or push and pull hard on the pedals. I also think the OP is a nicely dressed lady in skirts and street shoes, not in tights and cleated bike shoes. Finally, I think the OP should be able to get across the intersection quickly now, without first spending months in the weight room building thighs like steel thunder. So track start technique might be of limited relevance and a fixed gear bike would be a bad choice.
Practicing fast gear changing will be helpful. I can't recall if the bike has IGH or derailleur, but anyway it has indexed shifting so you can bang through the shifts quickly.

Your signature contains too many lines and must be shortened. You may only have up to 2 line(s). Long text may have been implicitly wrapped, causing it to be
He even mentions "vicious sprints" which is basically what you want to do if you are trying to improve your acceleration across an intersection. Maybe not "vicious" but you want to sprint.When you climb a super steep short hill, you actually can pull up on the upward-moving pedal for a few strokes, and doing so helps you turn over the other pedal
