(AI) in Infrastructure Projects—Gap Study

Infrastructure projects are usually complicated, expensive, long-term mega projects; accordingly, they the type of that most need optimization in design, construction and operation stages. A great deal earlier research was carried out to optimize performance infrastructure using traditional management techniques. Recently, artificial intelligence (AI) techniques were implemented improve their efficiency due ability with fuzzy, incomplete, inaccurate distorted data. The aim this is collect, classify, analyze review all available previous related implementing AI figure gaps studies recent trends area. total 159 collected since beginning 1990s until end 2021. This database classified based on publishing date, subject used technique. results study show rapidly increasing. They also indicate transportation first AI-using project both neural networks (ANN) particle swarm (PSO) projects. Finally, presented some opportunities for farther research, especially natural gas
