We now have a network map for TfC, and this has also prompted me to look again at the latest slimmed-down Kernow equivalent.
I am not convinced that giving each route its own colour really works. It is based, I imagine, on the London Underground map/diagram, but that uses very distinctive colours, and only needs about a dozen or so.
Bearing in mind that the most frequent user of the Kernow map will be someone unfamiliar with the area, there is plenty of room for misunderstanding.
For example, is the purple line in the Cornwall Services area bus route A30? Nope. It’s the 27. (Yes: it’s obvious enough to you or me, but what about visitors -- especially those from other countries?)
Why does a bus map show principal road numbers but omit the National Rail symbol at nearly all the intermediate places on branch lines? Lelant and Carbis Bay are honoured exceptions, but to make up for this although St Ives and Newquay are marked as places with stations Falmouth is not -- although it has three (not counting Penryn).
The road numbers oddity could perhaps be explained in a brief key, but there isn’t one (breaking one of the rules of mapping as taught to me at St Columb Minor Junior School!)
As for the colours, take the Carnon Downs/Devoran area. There are two routes here -- dark blue and sage green. Is the blue route the U1 or the 87? The two blues are pretty close in the palette, and I suspect their similarity breaks an accessibility rule or two.
Occasionally the map designer falls over his/her own feet. If you give both the former Tinner routes an identical red, you must add some roadside route numbers after all in a bid to make it clear that the T1 goes to Penzance and the T2 to St Ives -- and that the T2 has a little loop to serve Loggans while the T1 dives into the West Cornwall Shopping Park.
Incidentally, Porth Four Turns in suburban Newquay is not in Porth -- it's a crossroads in Henver Road which is quite a walk from Porth Beach! (A long-standing FK error.)
Finally, you might gather from this map that it shows the whole Cornwall network. There is a disclaimer about evening, Sunday & school day routes, so would a discreet note that ‘other operators also provide bus services in Cornwall’ really have hurt that much?
Coming next (if you can bear it), TfC’s equivalent effort.
