Functional efficiency of transport garages in Diyala Governorate

Abstract

The service industry represents the backbone of growth and development across various economic sectors. As regional transportation is a key component of this industry—closely linked to individuals' daily mobility—population density increases and evolving social needs have led to a greater diversity in transportation demands. These demands vary according to residential development needs, spatial suitability, the mode of transport used, spatial distribution, and capacity. Their development and planning must therefore align with the needs of both individuals and society.This research aims to identify the theoretical foundations of queuing theory and apply them practically to the transport garages in Diyala Governorate, evaluating their capacity to accommodate the growing number of vehicles to provide services and optimize space utilization. The study concludes that the geographical location of Diyala Governorate plays a significant role in shaping the patterns and types of road transportation systems, represented by main roads with a total length of 460.7 km within the research area, out of a total area of 17,682 km²—constituting approximately 4.06% of Iraq’s total area. The anticipated development of these garages depends on technical and service-related improvements, the provision of transportation facilities, and the enhancement of activities related to the movement of passengers and goods. These conclusions are supported by statistical confidence of up to 95%, based on calculations of daily and annual trips for both passengers and vehicles.
