Over the past 8 years or so my local council has spent 10s of millions improving road junctions.
Re-allocating lanes at busy junctions for left hand turns which very few use.
Adding a right turn filter light on many traffic lights where the filter has its own set timed sequence.
Replacing a large round-about with a T junction and adding to the mess a shared pedestrian/bus/taxi road. Include unsynchronised traffic lights on the junction so that when travelling in any direction motorists have to be ratcheted around 3 or 4 sets of lights in 200 yards.
Road narrowing at the other side of junctions to promote traffic calming.
The net result is traffic bottlenecks in various places/junctions where motorist are stationary for a very much longer period than before the road improvement.
Who could have predicted that the air quality in these areas of road improvements has deteriorated so much that the council has been forced to declare these locations as ?Air Quality Management Areas?? I wonder now if more 10s of millions will now be spent on the same junctions to remove some of the ?improvements ? in order to speed up traffic and not having it waiting at lights for so long? The council seem to be pining their hopes on everyone using a bicycle!
