My good friend Chris mentioned to me the other day that the reason subdivisions often times are curved or erratic, is the idea that straight roads make people feel unsafe. With only that to go on I decided to delve a bit into why that is. I have learned that the idea that roads should be curved in neighborhood areas is called coving. The original intent for the practice was to make it so that no houses could look directly into a home across the street or next door. As a side benefit, this can cut the costs of roadway and telephone poles. Rather than have two roads that connect in two separate intersections, (which, might I add are not an incredibly safe part of the roadway anyways) You can have a single winding road that covers the same area. This also forces variety when it comes to home building. A neighborhood can’t have rows and rows of uniform houses all facing the same way, if the front door does not quite align with the street. I am not sure how accurate he was when he ascertained that straight roads make people feel "unsafe." However, I do find it psychologically interesting that people would like to avoid their neighbors knowing their business so much that they invent a new way of designing roads.
