Performance of Al- Balda Signalized Intersection Using Arcgis

Raad mohsin hameed, Salih suliman Kshash

Abstract


         Signalized intersections are key elements in the urban transportation network where carry heavy traffic of motorized and non-motorized vehicles and pedestrians, which, in turn, generate many conflicts among crossing, turning and merging maneuvers. For these reasons such as increasing of the population, economic growth, and increased car ownership led to an increasing traffic demand can exceed the carrying capacity of the intersection during peak periods. Intersection congestion is expressed in terms of level of service (LOS) as defined by the Highway Capacity Manual (HCM). Level of service is defined in terms of delay and ranges from LOS A (free-flow conditions) to LOS F (long delays). Delay represents an average stopped delay per vehicle for a 15-minute analysis period.

 The objective of this paper is to evaluate the operational capacity of intersection (baquba). The volumes of traffic get congested   in the morning and evening at this intersection. To achieve the evolution performance of intersection 700 TVL Samsung video cameras have been used to measure traffic volume in the intersections with 3.6mm lens and total station were used to survey the intersection whereas ArcGIS were used for processing for the purposes traffic analysis process. The operational analysis of the existing conditions of this intersection indicates that the LOS is (F) with an intersection delay value of 175.363sec. /vehicle.
