The Possibility of Traffic Congestion Mitigation at Complex Interchange in Baghdad
摘要
The Baghdad city is expanding vehicles will soon be 3 million. The interchange is like a partial of a cloverleaf and part of another type of interchange, and it is considered a distinct and unique design in the world. The study evaluates the Baghdad Al-Jedida interchange congestion, the travel time the driver spends, and the traffic volume during rush hour (7:00–9:00 a.m. and 1:00–3:00 p.m.). Conduct a field survey to know the area’s nature and obtain information from the Amanat Baghdad. Collected field data in cooperation With the Public Traffic Department, using surveillance cameras, calculating the interchange dimensions through the Geographic Information Systems program (GIS), and using the PTV VISSIM program to analyze data. The current interchange design can’t accommodate the high traffic volume, and the level of service (LOS) for interchange was F and gas emissions from vehicles. The Maximum relative density is 92.90%, and the average travel time is 324.25 s. The study aims to reduce congestion at peak hours and improve the journey time. The level of service on the road with several solutions: Propose a new geometric design; heavy vehicle traffic during peak hours is forbidden. Transportation Demand Management (TDM) techniques are employed solutions used for both traffic volumes current and future after five years.
