In Pakistan, roads now handle 96% of freight, replacing rail as the main transport mode. This study uses ArcGIS's Important Zones Analysis and Multi-Criteria Analysis Techniques to determine Peshawar's important routes. The key route was identified, and congestion spots along it were further examined using passenger car unit (PCU) analysis, volume-to-capacity ratios, capacity studies, and Level of Service (LOS) calculations. An integrated strategy based on the Shannon Entropy method and the TOPSIS technique was used to rank high traffic congestion areas. Fuzzy TOPSIS analysis results revealed that Amin Hotel with closeness coefficient (C_i = 0.85) was identified as the most congested locatiScientific reports5036https://www.ebi.ac.uk/biostudies/studies/S-EPMC12876898biostudies-literatureEvaluation of traffic congestion mitigation techniques using an entropy-TOPSIS integrated method.PMC12876898Almoshaogeh MJamal AHussain DFarooq DAlharbi FFarooq AfalseEvaluation of traffic congestion mitigation techniques using an entropy-TOPSIS integrated method.Road traffic congestion is a major issue in many developing countries, including Pakistan.
