“Giving people more viable alternatives to driving means more people will choose not to drive, so there will be fewer cars on the road, reducing traffic for drivers.”
Concise, easy to understand, and accurate. I have used it at least a dozen times and it is remarkable how well it works.
Also—
“A bus is about twice as long as a car so it only needs to have four to six passengers on board to be more efficient than two cars.”
somehow even turborural areas here in sweden can manage it, so there’s no reason other places can’t do the same.
the crucial thing is that you don’t have to run public transport literally everywhere, just run robust services between population centres (as many ones as you can manage) and build infrastructure such that people can get to the closest stop and transfer onto the public transport there.
