Traffic congestion on city road networks is one of the main issues to be addressed by today's traffic management schemes. Traffic congestion on city roads many times leads to delay in emergency services (i.e. ambulance, firefighter, police, etc.). A survey on various traffic management schemes specifically designed to help emergency vehicle has been presented in this paper. Traffic management schemes used currently and their limitations have been discussed. Researchers have used several techniques such as embedded systems, wireless sensors network, intelligent ambulance and image processing for traffic management. These techniques have been discussed thoroughly and comparative analysis has been made.
