Traffic flow in a home, office or even a room is important not only for aesthetic purposes, but also for safety.  As we know, most accidents happen in the home and in order to keep a room both looking pleasant and inviting and actually being functional and safe, it has to have ample traffic flow.Traffic flow involves the ability of people to move about the room.  This is not only important in a room but also in an entire house.  Studies indicate that homes that have a smooth traffic flow pattern sell quicker than those that have a lot of dead space.Dead space in a house is space that is not usable because it does not invite others in.  Many homes have living rooms in the front of the house that do not flow into another area.  These rooms are often unused and “for show” only as they do not invite traffic.  Most interior design experts agree that for a home to be inviting, each room should be useful.  According to many in the design industry, dead end rooms should be limited to bathrooms and bedrooms.  Living spaces, such as dining rooms, family rooms, kitchens and living rooms should flow into other rooms to create a better traffic flow and encourage the rooms to actually be used.  The old fashioned notion of a living room being treated virtually as a museum is being replaced with those that are more inviting.  Traffic flow not only relates to the interior of the house, but also to the rooms themselves. There are ways to place furniture so that it allows the most ample traffic flow in a room, a situation that is for safety purposes as well as appearances.  There are many different ways to place furniture in both large and small rooms.  In interior design classes, you can learn how to make a small room look more spacious by placing the furniture against the walls.  The largest piece of furniture, by rule of thumb, should go against the longest wall. In a large room, to make the interior seem more cozy, you can place the furniture on an angle so that it looks inviting and creates an easy to maneuver traffic flow pattern.  Learning how too use furniture to its best advantage, especially when it comes to traffic flow in rooms is one of the basic principles of interior design.Interior design classes do not only teach traffic flow patterns for homes.  This is also important for apartment buildings and offices.  The easier it is to maneuver in a certain space, the safer the area is and more productive the people.  Creating stair cases and learning how to place them in a home in order to make sure that the risings are safe is another aspect of traffic flow that is learned in interior design classes.  Interior design is not just about décor, but also encompasses traffic flow, which plays a key aspect in design in both residential and commercial buildings.Many people who work in the interior design field study traffic flow in interiors and work solely for architectural firms where they design not only the most efficient but the safest interior spaces.
