Abstract This research focus on the main problems which face planners and traffic operators in urban areas; such as; low performance and efficiency levels of passengers transport system, while demand for transportation is growing rapidly. The strategy for tackling these problems has been for years to consider adding more capacity to the transport supply system, through huge investments in transport infrastructure. Best utilization of available transport services and facilities is an urgent necessity. This Thesis presents a methodology for transport modes operation analysis for different policies and strategies to be simulated to reach optimal goals. Transport modes operation performance and efficiency are formulated in a framework as an output maximization process of an objective function, subject to state variables, decision variables, constraints and variable bounds. Methods developed in the theory of optimization, through making use of advanced computation technology, would allow one to make experimental analysis and evaluation of different policies and strategies for better understanding of the transportation problem and to select a solution for efficient utilization of resources. Four main traffic operation strategies which would have great impacts on urban transportation performance and efficiency were analyzed by using optimization techniques through developed algorithm containing the principal structure relationships that exist among the various components involved in the overall management of transport system. Developed strategies contain heuristics of many trail values of decision variables. The scope of research is a practical methodology to identify route, associated passengers’ modes and flow rates to serve demand and that leads to minimize overall transport system costs. iii The research output reveals two important indicators for alternative transport systems evaluation; passengers Mode Efficiency Factor (M.E.F) and passengers transport System Efficiency Index (S.E.I). Efficient transport system supply to satisfy a specific demand was investigated, also identification and clarification of most compatible transport modes suitable for passenger demand sharing which would give optimal performance indicators were documented. |
