From Artificial Urban Transit System to Parallel Service Management
Speaker
Abstract
| Urban transit management is a challenging job that deals with millions of passengers every day. However, do we really understand how passengers behave? Even if we do, do we take that into consideration in the planning phase or daily operations? In our work, we employ the concept and techniques of ‘artificial society’ to model and simulate this complex system and try to answer the questions like ‘what if the service frequency is doubled for Route 9?’ or ‘what if there is a major sports event in the stadium?’, which lead to the idea and development of Artificial Urban Transit System (AUTS). With AUTS, which is a special type of Artificial Transportation System (ATS), we are able to dynamically model the passenger’s behavior and route choice and use the system to predict transit demand on a simplified transit network. If we go one step further, making this artificial system execute in parallel with the real system, we are then doing Parallel Management, which is a new direction that leverage the unique strength of Agent-Based Modeling and Simulation (ABMS) to develop the artificial systems and further support the decision making for the real systems. In our research group, it has been extended to different service systems, e.g., healthcare, retailing. |
