Circulation is a basic fundamental of any landscaped space and can be very frustrating to the people using the space if it is not done correctly. In most cases, there should be a closed loop of continuous flow from and to all entrances and exits to a space – there shouldn’t be a lot of dead ends and closed corridors. So you wouldn’t want to plant a hedge halfway across the middle of a lawn area and make people walk a long way out of the way to get into the next space.
The old saying, “the shortest distance between two points is a straight line” applies here. However, that doesn’t mean that you have to have only straight lines; it just means that you should remember that there are two points and that most of the time you want both a major and a minor access to them. Having choices makes people feel in control and adds to their satisfaction with the space that their in. Having a continuous flow of traffic through your space gives people choices and keeps things moving in a natural way.
