The Convenience-Compliance Nexus in Urban Parking: Evidence from Abuja, Nigeria

Illegal parking is a persistent urban management problem that affects traffic flow, pedestrian safety and the efficient use of public space. Although parking shortages are frequently identified as a cause of non-compliance, motorists also weigh proximity, convenience, time pressure and the perceived likelihood of enforcement. This study examines the convenience-compliance nexus underlying motorists’ parking non-compliance in Phase I of the Federal Capital City (FCC), Abuja, Nigeria. A mixed-method design was used, combining a structured survey of 384 motorists with field observation and spatial assessment. Descriptive statistics, one-way analysis of variance and multiple linear regression were used to examine parking practices, district variation and predictors of a Parking Non-Compliance Index. Parking non-compliance was widespread: 80.5% of respondents reported having parked in an unauthorized area. Sidewalk/pedestrian-path parking had the highest behavioural mean (M=4.20, SD=1.06), followed by parking in front of shops or businesses without permission (M=3.90, SD=0.99). The reconciled regression model was statistically significant, F (7,376) =54.27, p<.001, with R²=.503. Shortage of parking spaces (β=.362), convenience/time saving (β=.254), time pressure (β=.218), and weak enforcement (β=.174) were significant positive predictors of non-compliance (all p<.001). Social norms (β=.082, p=.074), parking fees (β=.079, p=.069), and signage clarity (β=-.061, p=.184) were not statistically significant. The findings indicate that parking non-compliance in Abuja is better understood as a structural-behavioural-institutional problem than as a simple failure of driver discipline. Effective management therefore requires coordinated improvement of legal parking availability and accessibility, visible and consistent enforcement, and parking arrangements that reduce the convenience advantage of illegal locations.
