I always wonder if, at busy pedestrian intersections, it would make more sense to have the pedestrian flow stages and the vehicle flow stages be totally separated. Cars waiting to turn right for ~30s as pedestrians walk is kinda crazy.
New York uses Leading Pedestrian Intervals, which give pedestrians the green before the cars can turn right; by the time a driver starts turning pedestrians are actively crossing the street and no longer in the blind spot. Another good way to increase pedestrian safety is just to ban right-on-red altogether.

Have a look at Sumo, its free, open source, and comprehensive. Also Aimsun [1] but I've never used it and don't think it's free although I'm unsure about that.
