Traffic signal control with swam intelligence ant colony optimization
Ant colony optimization (ACO) is a meta-heuristic based on the indirect communication of a colony of artificial ants mediated by pheromone trails with collaboration and knowledge-sharing mechanism during their food-seeking process. ACO has been successfully applied to solve many NP-hard combinational optimization problems such as travel salesman problem, quadratic problem, just to name a few. In this research, we apply the ACO algorithm to the traffic signal control in order to minimize the user delay at a traffic intersection. Simulation results from our computational experiments indicate that ACO provides better performance during high traffic demand, compared to the conventional Fully Actuated Control (FAC).
