Deliberative Self-Organizing Traffic Lights with Elementary Cellular Automata

Figure 4

Rule attempts to turn a red light green when many vehicles approach it. Rule prevents fast switching of traffic lights for high densities and also prevents a street from having always a green light. Rule prevents “tails” of platoons from being cut, promoting the integrity of platoons. Rule allows a quick change of lights at low densities, as isolated vehicles can activate the lights change as they approach an intersection without requiring them to form platoon. Rules and prevent gridlocks caused by stationary vehicles at intersections, while allowing flow in directions with space downstream.
