Brockville’s official plan, like any other, declares that public roads exist to move people and goods.
A current and comprehensive transportation plan, which Brockville does not have, would then go on to stipulate the relative priority given to different modes of transportation and then go into some detail on the current and future transportation network of the city. Cities usually define the modal priorities as pedestrians, then cyclists, then transit, with private automobiles last.
The linked article describes how the city of London England has greatly improved the overall efficiency of their transportation system by designing and implementing roadways that match their priorities. This includes designated bicycle highways as well as facilities on shared roads. When people are offered choices they perceived to be viable as well as safe then more rational outcomes result.
In London, the result is a system in which cycling proves to be five times more efficient than driving, without even considering the associated health and environmental benefits.
