This Study evaluates on-street parking in Ilorin Central Business District (CBD), Ilorin, Kwara State. It examined the on-street vehicular parking mode and its impact on flow of traffic in the CBD. The study adopted a survey research design using the primary and secondary data sources. A sample frame of 4,543 respondents was determined through parking volumetric count that was conducted between 7:00am to 7:00pm. Questionnaire was administered to 354 motorists who parked their vehicles on the street, using accidental sampling techniques to elicit information on parking characteristics. All the six major roadways that criss-crossed the CBD were all selected for the study. Descriptive statistics tools was used to analyse the data while vehicle to capacity ratio was used to evaluate the impact of on-street parking on traffic flow. The study revealed that 57.9% of the respondents’ vehicles were parked on the street for the purpose of business and work. Further finding indicated that 61.4% of the motorists parked on the road curb because of inadequate or lack of off-street parking facilities in the city’s CBD. Traffic flow was stable in the four major roadways selected with the exception of Ibrahim Taiwo Road where traffic flow was not stable and queues developed rapidly as this contributed to traffic congestion along the road corridor. The paper recommends among others the provision of adequate and designated on-street and off-street parking facilities, regulation of parking by introducing park and pay to discourage on-street parking.
