Gridlock

Ever wanted to manually control every traffic intersection in a city? Gridlock allows you to do just that. Your goal is to set up intersections to ensure optimal flow of traffic. You can assign different types of traffic flow to each place. You can test particular routes. Or you can run a full-scale test with all of the cars. Most of the game is in text mode but the observation mode to view the cars is in a graphics mode. The interface is not particularly easy to use, and there is a lot of text in the included docs to try to explain how everything works.

This is the same game as Gridlock, which has the full page.
