I'd like to ask a relatively simple question – what would happen if we switched of traffic lights when we didn't really need them? I'd like to know from an environmental aspect what effect turning off the nations traffic lights would have towards saving electricity and reducing emissions. From a social point of view could the nation's road users manage with such a change? And from a technical innovation view point – could it and should it happen and if so how?
