Highway capacity is much worse: the busier the road, the lower its peak-hour capacity. Cycle lanes, bus lanes, footpaths and light rail all use road-space more or much more effectively than motor traffic, provided that they are not stuck in motor traffic. Their people-carrying capacities in a traffic-lane are some 6 to 10 times greater than motor traffic, and much less affected by overloading. Some have to drive, some choose to drive and some choose public transport if it is quicker. LGWM's proposed second route is the quays and Taranaki St. Two bus lanes would work, but would soon be overloaded.
