However, because of the limited scope of bus lanes here and the UK in general, they've probably only prevented frequency reductions, rather than generate new services as the savings are small compared to the time needed to invest elsewhere.
The political will for the number of bus lanes at the scale needed to have a tangible impact just isn't there.
If buses were a genuine, viable, affordable option - bus lanes wouldn't need to exist.
They're only there, because of the amount of cars on the road.
