Development of roundabout delay models using traffic simulation programs: a case study at Al-Mansour City, Iraq

Due to the increased number of vehicles, shopping centers and rapid growth population of Al-Mansour city, daily trips have been increasing besides generating traffic congestion in major roundabouts in the city. Those will make developing an imperial delay model in roundabouts important due to the tr...
