Samenvatting
An optimal control model is presented that characterises the changing states of system capacity and allowable traffic volume as a result of transport planners' investment in mode-specific infrastructure, e.g. bus-lanes, or road maintenance as well as his financial sustainability constraint. A common throughput-based optimisation criterion is compared with an accessibility based criterion. The feasibility is demonstrated for a case study, which is representative for a developing city.
