SIGNS AS DETERRENTS OF ILLEGAL PARKING IN SPACES DESIGNATED FOR INDIVIDUALS WITH PHYSICAL DISABILITIES

The percentage of illegal parking in spaces reserved for the physically disabled was monitored under three sign conditions: ground markings, ground markings plus vertical signs, and vertical signs containing a message that concerned citizens were watching the spaces. Illegal parking dropped from 69.3 percent of 102 vehicles during the initial ground-sign condition to 57.3 percent of 36 vehicles in the first vertical-sign condition. Following removal of the vertical signs, illegal parking increased to 68.7 percent of 43 vehicles. During the second vertical-sign conditions, illegal parking dropped to 53.7 percent of 32 vehicles, followed by an increase to 69.5 percent of 68 vehicles after the vertical signs were removed. The lowest rate of illegal parking (27.1 percent of 78 vehicles) occurred in the vertical-sign-plus-message condition. Illegal parking subsequently increased to 34.6 percent (of 94 vehicles) when the message sign was removed, followed by an increase to 65.2 percent (of 105 vehicles) when the vertical signs were removed.
