You may have heard a time bomb by now, we have one. Cities have signals at intersections. Every signal needs to have a timer. So that people know how long the signal is going to take. Stopping the vehicles at the signal will save petrol and reduce pollution. For this, we inspect each signal, see if there are timers, see if they work properly, if not, we report them to the concerned post and follow it up and get the timer in order. Where there is no timer, we demand the installation and, follow up, for the same and install a one. We appeal to the people to stop the vehicle when they stop at the signal to reduce pollution.
