If you have central control you might even be able to get away with changing the rules. i.e. most roads are now one-way leading out of the city. voilà we nearly doubled outbound throughput. Even just for commuting that would be awesome, not that it is happening anytime soon, but one can dream, especially while sitting in gridlock traffic.
Having the middle of five lanes change direction depending on the hour is fairly common. There's even a dedicated machine to move a concrete barrier to support this.
