The level of sustainability (LOS) for urban transport T.-P. HSU Institute of Civil Engineering, National Taiwan University, Taiwan Abstract The sustainable development concept will dominate transport development in the new century. In this paper, an assessment model of level of sustainability (LOS) has been created based on an optimal modal split by sustainable goal, with the view that a modal split can reflect a transport system if it is car-oriented, transitoriented or non-motorized oriented. The most sustainable modal split of urban transport is the non-motorized mode of 70%, public transport of 30% and car and motorized transport at 0%. The indicator for the level of sustainability for urban transport is defined as the distance between the existing modal split and the most sustainable modal split. The LOS indicator value has a range from the most sustainable value zero to the most unsustainable value of 126, and is divided into six classes from class A to class F. The first, i.e., the best
