We could debate the term "motor traffic capacity" :)
What's "better":
a) a 1 mile queue of vehicles feeding into a single lane bridge, left lane relatively empty for left turners and two wheelers
b) a 1/2 mile queue of vehicles, both lanes chocker, no room for anything on two wheels, left lane merging in the middle of the junction.
The flow rate on the bridge is the same - it's a single lane - but with both lanes full, left turners and other road users are stuck in the queue.
Using both lanes just moves the bulge along. It doesn't increase the flow on a larger scale. Does it? iamnotatrafficplanner
