David Staples: To avoid another LRT fiasco, go with bus rapid transit to West Edmonton Mall

Instead of building an LRT from downtown to West Edmonton Mall and beyond, we should go with bus rapid transit (BRT).
Why? 
First, to avoid building an expensive and inflexible system that can’t be easily changed if there are major mistakes. Second, BRT represents a more flexible system that moves people at LRT-like speed. Third, BRT costs far less to build than LRT, which should allow the city to expand its mass rapid transit system in other directions.
