A Model to Improve Workability of Transport Systems

This research addresses the environmental dynamics of transport systems to increase its workability. The most influential factors on workability are security level, health factors, effectiveness, comfort, practicality, affordability, safety, and user perception. As a tool for model development, we utilized a system dynamics framework to accommodate relationships between complex and nonlinear variables that influence the workability of transport systems. Stock and flow diagrams were used to model and predict the workability of the transport system based on the existing conditions and project workability in the future through several proposed strategies to improve workability. The main contribution of this research is providing causal relationships of variables and parameters that influence the workability of transport systems, model and simulation development of several subsystems that influence the workability based on the existing condition, and scenario modeling to predict and improve the workability in the future. The workability of the transport systems can be increased by improving health factors, safety aspects, and energy conservation to support practicality, comfort, perception of the transport system, effectiveness, affordability, and practicality of the transport system. Through scenario modeling by changing the structure of the model, projections on the future of the workability of transport systems can be estimated.
