Saw a new signal post @ the junction of Sarasbaug/ peshwe park road with Bajirao road in Pune. The signal has a psuh button to stop the traffic for a few seconds if somebody wants to cross the road. Particularly useful for older people/ children.
Tried it by pressing the button, 2-3 times. but it was difficult to judge the system was working or not, as the traffic was flowing heavily at around 7pm.
