Abstract
The article examines the study of public transport accessibility as an important tool for enhancing social integration in the Republic of Kazakhstan. Particular attention is paid to analyzing factors influencing pedestrian movement to public transport stops and passenger trips. A two-stage theoretical and experimental model of pedestrian and public transport interaction is presented, aimed at optimizing stop locations and improving transport infrastructure. The use of the a priori ranking method of factors allows identifying the most significant ones, such as distance, approach time, pedestrian speed, and climatic conditions. The application of similarity and dimensional analysis theory helps more accurately predict system behavior under various conditions, contributing to more effective transport network planning. Using dimensional analysis theory, a new mathematical model for justifying the locations of public transport stops is proposed. The experiment's outcome is the determination of optimal stop locations for public transport trips.
