A traffic control system refers to a set of technological tools and methods designed to manage and improve traffic flow on public thoroughfares, intersections, or intersection points. The main goal of these systems is to reduce traffic, increase safety, and improve the efficiency of transportation networks. The issues that make this difficult are population growth, the increase in vehicles, technological limitations of traffic signal control devices, lack of traffic congestion management on roads and intersections, and inadequate urban infrastructure, which has become one of the critical problems and challenges in improving traffic and traffic management in Kabul city. Increased road congestion, travel time, number of accidents, carbon dioxide emissions, and fuel consumption are some of the messages of the aforementioned problems and challenges, because currently, traffic control in Kabul is mostly done through traditional and manual methods. Traffic police control traffic at key points, but these methods are not as effective as they should be. On the one hand, traffic congestion control systems are not smart and up-todate, and on the other hand, there are numerous other complexities, options, and criteria that affect Kabul's traffic control systems. Therefore, methods and systems for controlling traffic congestion in Kabul city require a research approach with a combination of multi-criteria decision-making techniques (Analytic Hierarchy Process and WASPAS). In this research, 22 types of traffic congestion control systems for Kabul city were examined and analyzed, and each system was compared with different options and criteria, including: cost, lifespan, accessibility, ease of use, flexibility, electricity consumption, internet consumption, performance, and intelligence of the systems. In this research, the necessary information was collected mainly through library study and consultation with experts, predictions of a group of experts, and in cases of necessity, by in-person interviews with them, for the analysis of the hierarchical method. After collection, the expected criteria and options were identified and weighted, and finally, with the help of the WASPAS technique, the various criteria and options were analyzed and ranked, better and expected solutions were proposed in the traffic congestion control system of Kabul city. This research shows that among 22 types of traffic congestion control systems, the LED traffic signal control system, ranked first, is the best option in the long term. The automatic traffic signal controller using Arduino is ranked second and the audible and visual alarms are ranked third, while the remaining systems were ranked lower due to Kabul conditions.
