One thing to keep in mind is that the timing for traffic lights needs to consider the slowest pedestrians. It may well be that your average 20 year old is 20 yards down the road by the time the signal changes, but that time may just be sufficient to cross the road for a 70 year old. Traffic lights can't sense how long it'll take people to cross the road (yet), so you need to presume they will be slow.

Yes but the flashing amber light was to allow those who needed more time than the sprightly 20 year old to finish crossing, yet under normal circumstances the average wait time gets reduced. Even with the amber light the crossing red time to traffic was still set to allow sufficient time for most people to get across with traffic stopped.

Driving through central Manchester every morning to work I see that this isn't the case. Even if nobody is waiting to cross, all the lights at a four way junction turn red & the pedestrian lights turn green. This holds up traffic for no reason & increases journey times and pollution unnecessarily. This is known as a 'full pedestrian stage'.

This has been picked up on by the RAC Foundation...

Drives me mad! :mad:

It's got to the stage now where the pedestrians control the traffic.

There's a road near us where the local Council installed a new pedestrian crossing 3 years ago, it's a nightmare right from the word go in a morning right up until the traffic dies down about 6:30pm, the pedestrians are forever pressing the button stopping the traffic, it lets 2 cars through at the most. At rush hour the traffic can tail back well over Â½ a mile due to the crossing.

There was nothing wrong with the old one so why fix something that isn't broken?? When it was cold in December they were stuck on green, there wasn't any hold ups then.:D
