Hello François, 1) Finding the optimum program for a single intersection is feasible 2) Finding the optimum program for a network of traffic signals is complex. Instead of computing the optimum, heuristic search is typically used to find a good non-optimal solution (i.e. genetic algorithms) 3) A lot of research is undertaken to build controllers that optimize each intersection individually in a way that also gives a good solution for the whole network. This is another attempt at approaching the actual optimum. regards, Jakob
