Traffic Light Update
Traffic Light Local Update for Jacobs Well about the recent traffic lights replacement at Slyfield - A320 Woking Road /Moorfield Road.
I placed this on my Facebook Page: www.facebook.com/keithwitham1 but appreciate that it may not be seen by some people. If you use Facebook do please have a look and "follow" for future local information.
But last week some residents asked me about this as the works had caused severe traffic congestion on the first one or two days.
Background. Firstly, they were being replaced as they had become obsolete, installed in 1999 with components no longer available. They were also at risk of becoming structurally or electrically unsafe if not replaced soon. The works are part of a Surrey County Council programme to replace traffic lights across Surrey - to keep our roads safe.
The permanent traffic signals had to be switched off as they were being removed and temporary signals put in place. Unfortunately temporary signals can never be as "intelligent" as the permanent signals and delays to traffic are unavoidable. Also, due to the right turn into Moorfield Road each approach had to be run separately, so the signals were set to three-way operation. Alas this caused delays to traffic. Lanes have to be closed to provide a safe working space to protect the workforce, which does reduce the road capacity. So the timings were adjusted as much as possible within the limits of the temporary signals (to their maximum setting) to alleviate congestion, and the daytime working hours were extended.
SCC scheduled the works to be completed in two weeks, barring any unforeseen circumstances, but then asked the contractors to run the signals on Manual during peak times following the delay problems on the first day of the works.
As the life expectancy of traffic signals is 10-15 years, this particular junction should not need to be refurbished again for that period.
WHY NOT NIGHT WORKING? I was also asked why night-working was not adopted to reduce the disruption. Unfortunately it was not practical to work at night as part of the work involved wiring signal equipment with many different coloured cable cores needing be connected to different components. Even with torches and street lighting the colours could be wired incorrectly as colours change under artificial light.
It would also have incurred more than double the cost of the work, funded from a limited budget, meaning that SCC would have to reduce the number of jobs on the programme.
The second week of the works were planned during the one week Half Term school holidays, which was the best planners were able to do for programming the work for a less busy period.
If you want it, further information can be found on the SCC website via:
I hope this is helpful, and explains the position, as I appreciate that this caused some considerable local disruption. But SCC did it's best to reduce the time needed, and as mentioned earlier the work was in fact completed four days ahead of the original schedule.
