A parking management and guidance system keeps track of large parking spaces that cannot be monitored without employing a large number of monitoring staff. Places like airports, shopping malls and dedicated parking lots require efficient monitoring of occupied and vacant parking spaces. The parking guidance system helps the on-site management staff to effectively guide the incoming vehicles towards vacant spaces, the fact that helps avoid undesired congestion in various sections of the parking lot, as visitors tend to follow a similar route while searching for parking spaces.
