State and local governments are required by law to provide and maintain accessibility on their pedestrian facilities. They need to conduct, document, and update self-evaluations to identify non-compliant pedestrian facilities. This paper presents the development of a novel model for analyzing the compliance of pedestrian facilities with accessibility requirements. The model provides original and unique capabilities that enable decision-makers to: (i) quantify the degree of non-compliance of all types of pedestrian facilities including transit stops, on-street parking, and passenger loading zones; (ii) estimate cost and labour-hours needed to achieve compliance; (iii) prioritize upgrade projects for pedestrian facility types; (iv) rank pedestrian facilities upgrade projects in multiple geographical regions based on their collective degree of non-compliance; and (v) classify pedestrian facilities based on the type of required upgrade. A case study that includes 1327 pedestrian facilities is analyzed to evaluate the performance of the developed model and illustrate its capabilities.
