As the number of dead people increases, due to the delay of ambulance and different types of emergency vehicles on the crowded roads in major cities. One obvious solution to this entire problem is find way for the ambulance to arrive to hospital as fast as possible.

Highway all over the world is divided into three parts, fast track, middle track and the slow track. The smart highway system for emergency purposes (SHSEP) is an electronic system that enhances highway road by using a retro -reflective safety device used in road marking and make retro-reflective safety device light up, also known as cat's eye, to warn vehicles in the fast track of the ambulance arrival so they can move to the middle track, providing a clear path for the ambulance to reach the hospital as fast as possible and the driver of ambulance can call the traffic center before move from patient house to know condition of highway and know if highway available for ambulance or use other highway .

Table of remote control that inside ambulance to control fast track in highway:

*H≡ high, L≡low, S≡S witch This table explains the smooth passage of an ambulance on the highway, ranges on real life represent a group of light cat's eye, when ambulance passing a first range vehicles returning to use the first range ,when ambulance passing first and second ranges vehicles returning to use it ,when ambulance passing first and second and third ranges vehicles returning to use it and when ambulance passing first and second and third and fourth ranges vehicles returning to use all fast track (in this case I'm using four ranges you can use more than four ranges).
