As you all know it has been pretty cold out there recently and the gritters have been going out on a fairly regular basis, we’ve all seen the updates on Facebook, Twitter and Instagram, but what do those coloured routes actually mean? Well do not despair as I am here to bring you the information you are looking for.
There have been Four groups of road which Torbay Council have identified within the primary salting network, which have been taken from from the Thermal Maps of Torbay. All of these routes, or a combination of these routes can be selected at any time for treatment. The four colours of the groups are Red, Blue, Green and Yellow. Red is the coldest area and Yellow is the warmest. So, now you know the names of the groups, just look here to see which roads they cover.
Primary Salting Network…What does it all mean?
And just incase you wanted to know, here is a little more info 😉
Throughout Torbay we have a primary salting Network (sounds Fancy) and this is made up of strategic routes, so this includes: Main distributors, link roads, bus routes that have services that start before 8am, or where they are carrying traffic from a larger village to a strategic route or a main distributor. As well as these routes the primary salting network also includes access to fire, police and ambulance stations, hospitals, royal mail (so we still hopefully get our post 🙂 ) and the bus depots. And to make sure all services can continue as normal as possible included is any roads that join neighbouring highway authorities gritted networks. So if we work or go to school outside the Bay as the least we know they are trying to still get us there if the weather turns really icy!!
In Torbay the total Highway network stretches across 520km, that is longer the length of the Grand Canyon! So you can imagine how expensive and impractical it would be to salt the whole of the network. The Torbay Primary salting network covers 192km of all the roads, to give you an idea that is the equivalent of going across the Tamar Bridge just over 341 times, why you would want to do that I am not sure!
It is not an easy process to know when and where needs to be gritted. I mentioned Thermal Maps briefly earlier, a thermal mapping survey of the highway network is first carried out on behalf of Torbay Council as this enables thermal differences between known locations on the network to be identified ready to go for various weather scenarios. This information is then taken and compared with the weather forecasts that are sent through which means an effective prediction can be made if the locations and time of day/night that the gritting needs to take place. Pretty cool isn’t it?
Hope you found everything you were looking for.
Next time you a see gritting update you know where to just look here for more info.
Always happy to help.
