Downtown developers have complained that COTA passengers waiting for transfers near Broad and High streets, and buses lining the curbs make the area less attractive for retail stores and their customers...
Transit-dependent riders who are going through Downtown, for whatever reason, don’t shop… Large numbers of people waiting for a transfer can be intimidating for someone walking down the sidewalk.
Translation: People who buy things want to be protected from knowing about and interacting with people who are too poor to buy things.
