Basic Methodology for Selecting and Substantiating Iraqi Urban Public Transport Modes

Abstract

Purpose: Improving the urban public transport (UPT) system to ensure its efficient operation in Iraqi cities. Choice and justification of the urban transport mode in Najaf (Iraq), which will improve safety and speed of movement of passengers. Justification of the application areas for different types of transport in Iraqi cities by optimizing and selecting modes of passenger transport based on traffic volume, passenger density and urban characteristics. Methods: Statistical processing, functional analysis, mathematical modelling, probability theory, analysis of urban passenger transport in Iraqi cities, classifying Iraqi cities by main characteristics: population density, area, level of motorization, the maximum length of the territory, analysis of passenger traffic intensity and average capacity of the rolling stock. Results: New boundaries of average passenger flow density intervals have been adjusted for groups of Iraqi cities, allowing for the selection of the type of UPT and its share of transportation for each type of rolling stock. A distribution of urban transport modes has been proposed, taking into account the characteristics of Iraqi cities according to their classification. Practical significance: The application of the developed proposals and activities allows: to justify and select the types of urban transport systems for the city of Najaf; to calculate passenger traffic on six different routes with maximum traffic for the city of Najaf; to determine the classification of rolling stock capacity series and the UPT options for Iraqi cities; to provide recommendations for the development of the transport network of Iraqi cities. The proposed distribution of urban transport modes improves public transport services and the quality of use of each mode of transport.
