"It could take a few years, but Toronto is looking at making transit-friendly changes to one of Canada's busiest roads, including a bus-only lane to unplug the congested expressway.

There's no room to expand, but officials want to squeeze buses onto the centre median lane to let transit users zip ahead of car drivers in the regular lanes.

The concept, already used in Los Angeles, Minneapolis and Ottawa, would help GO Transit buses draw more passengers out of their cars, said managing director Gary McNeil."

D: Toronto had high hopes for hybrid buses. But they are not much more efficient for long steady driving.

D: this is a nifty setup. It uses an all-electric at the wheel.
It is powered by a small steady generator that recharges the battery banks.
