The performance of pedestrian facilities needs to be measured to enhance the popularity of walking as a mode which is termed as Pedestrian Level of Service (PLOS).

The present study attempts to give a comprehensive overview of the studies conducted on PLOS for sidewalks using Preferred Reporting Items for Systematic Reviews and Metra-Analyses (PRISMA) guidelines. The overview was carried out focusing on the literature published till 2022 all over the world. A total of 25 papers obtained from Google Scholar were reviewed. The main objective of the study was to analyze the available literature on the basis of study locations, methods of data collection, parameters considered and analysis techniques used. Overall findings across the literature reveals that a large number of studies were conducted in India. It was found that the dimensions of the sidewalk were the factor that was most frequently considered in most of the studies. Regression analysis was the most commonly used model to analyze the PLOS. The key insights and limitations of the study are discussed. In the end, conclusions and scope of further research are also presented.
