Access aisles, or the diagonally marked spaces adjacent to accessible parking spaces, provide many people with disabilities the extra space they need to get in and out of their vehicles. If this area is blocked even a small amount, a person with a disability may not be able to exit or enter their vehicle. To date, the research focused on specifically the access aisle is very limited. The purpose of this study was to deter the number of parking violations in which drivers encroach upon or park on top of the area designated by the access aisle. First, a qualitative study solicited the participation of people with disabilities who use access aisles for a focus group in order to gain more insight regarding both the frequency and severity of access aisle parking violations. Second, a quantitative study tested the effects of multiple interventions to reduce access aisle parking violations. The effectiveness of various signs and pavement markings to deter access aisle parking violations was investigated at Site 1 using an A-B-A-C design, where the interventions were not observed to have an effect. A quantitative study at a separate parking lot, Site 2, tested the effects of parking space width manipulations using an A-B-C-A design. The Site 2 manipulations were observed to demonstrate experimental control between the decreased width of the accessible parking space and subsequent access aisle parking violations. These findings suggest that current state initiatives to address access aisle parking violations (e.g., signs and pavement markings) may not be effective alone in deterring the frequency and severity of these violations. Instead, future policy may refer to these findings, which suggest that the width of the parking space itself influences the frequency and severity of access aisle parking violations.
