Traffic congestion nowadays leads to a strong degradation of the network infrastructure and the high number of the vehicle which is caused by the population. With an increase in the number of vehicles and transportation demand, traffic congestion occurs. Conventional techniques are unable to handle variable flow with time. Hence the accident ratio increases. We all know that in order to control traffic and for the safety of the public, traffic signals are used. These signals are generally seen where two or more roads are connected to each other. These traffic signal rules are not generally followed by the people either due to lack of attention or due to the speeding of vehicles which causes accidents frequently. Though accidents due to lack of attention to traffic signals cannot be avoided but accidents due to speeding of vehicles near traffic signals could be avoided. In order to avoid such kind of accidents near traffic signals, a ¿smart signal system¿ should be introduced.
