TfL To Introduce Automated Predictive Signal Timings, In Response To Forecast Traffic Conditions...by Jim Thomas

Transport for London is to procure (at great expense to the tax payer) an automated predictive signalling system that adjusts traffic signal timings in response to short-term forecasts of traffic conditions.

This could be a disaster for London's road users, remember that during the Olympics they said they would be tweaking the signal timings in real time to cut queues. Then realised after, they had no record of what the timings were originally to return to after the Olympics finished. 

As ranks and highways officer for the UCG, I was invited along with colleagues to see the nerve centre of the operation, at Centre Coms in Palestra. When I asked questions about the then daily traffic congestion and why this system wasn't being trialled we were hurried away. 

When I later blogged about what we had seen, the deputy director of LTPH did her best, to get the article taken down. But my concerns were proved right and after the Olympics the tweaking had left London's traffic phrasing in a right mess.

It is said this new system Is to PREDICT likely congestion and then take active steps to prevent it occurring, or minimise its effect. You have to wonder if these predictions will be done by the same people who had advance knowledge of the Hammersmith flyover closures.

TfL’s director of road space management, Alan Bristow, 
said the system would be “at the heart” of a new surface intelligent transport system (SITS) that will also see TfL’s existing urban traffic control (UTC) system replaced. 

This should be interesting, considering the mess on London's road network which has been caused by a program of extensive road works and resurfacing, spearheaded by massive 24 hour congestion along the Victoria Embankment towards Tower Bridge (which itself is soon to be closed for a number of months).

Short-term traffic forecasting is an area of growing interest in road network management said Bristow. But then it would be, it makes their highly paid jobs seem worthwhile. Plus, when London grinds to a halt, they can always blame the computer.

How come other trade org blogs are so annoyingly benign
No wonder the trade isn't united, there is never any information about what's going on. Apart from a few voucher winners for displaying a diary and letters thanking reps for helping with parking tickets, there's no substance to trade news in the trade media. Why is Oddy still involved with the LTDA, he should have been pensioned off. That would give him no conflict of interest on the board of TfL and he would be able to ask questions like Why hasn't Daniels been sacked.

"No record of previous traffic light timings", That there alone, speaks volumes on TFLs mismanagement. It's either total incompetence, duplicitous controversial planning for an agenda or a malevolent mendacious mentality. I'll go with the latter two, as we have already experienced the devious nature of the TFL beast.

TfL couldn't organise a piss up in a brewery

If tfl organised a piss up in a brewery there would be a single file wue to the bar with an enforced 10 sec pause between each customer. You wouldn't be able to find the toilets due to a forest of signs, but then you realise the que going in the other direction is you fellows waiting for a leak.
Meanwhile uniformed bods fine drinkers for leaving beer unatended and standing in the wrong places, over in the corner there is a desk charging for a licence to buy food. Tfl stands for total flipping lunacy.
