Comparative Study of Urban Traffic Management in Reducing Accidents in Tehran Using Analytic Hierarchy Process and Delphi Methods

Planning has been ineffective for dealing with problems associated with long traffic jams occurring due to atmospheric instability, crashes, and inappropriate road engineering in Tehran city. This has led to subsequent pollution problems, faced the citizens with many daily challenges, and eliminated the opportunity for appropriate measures to manage urban transportation and traffic. Today, comparative studies are used to achieve optimal transportation management in most countries. The aim of this study was to improve the transportation and traffic management in Tehran city by understanding the concept of transportation and traffic management, studying related literature, formulating effective factors on the transportation and traffic management in 22 districts of Tehran, and ultimately ranking them based on their weights. The state of transportation and traffic management in the 22 districts of Tehran was evaluated by descriptive - analytical methods using the analytical hierarchy process (AHP) and Delphi techniques. The statistical population included experts in various areas of traffic and urban services. The results showed that the 13th district was better than the others in terms of urban transportation and traffic management, with a final weight of 3.93. It is suggested that in order to optimize the management of transportation and urban traffic in Tehran, weights of components be taken into account for each urban region and be considered in the planning and management of transportation and traffic.
