Conclusion

Modern actuated controllers give the traffic engineers a great deal of flexibility in dealing with variations in demand. Area traffic control system along with Vehicle actuated signals can reduce traffic delays substantially. These are highly complex subject. Timing of VA signals is almost as much an art as a science, and more then one solution is possible. Regarding ATC systems, SCOOT and SCAT are popular in advance countries but such systems cannot cope up with Indian situations without adaptation to Indian traffic scenario. Presently, an advance ATC system known as CoSiCoSt has been developed considering the Indian Traffic scenario.
