Demand matrix adjustment for multimodal freight networks Crainic, Teodor Gabriel et al
Publication details: Transportation Research Record, 2001Description: nr 1771, s. 140-7Subject(s): Bibl.nr: VTI P8167:1771Location: Abstract: The problem of adjusting freight demand matrices to observed flows for multimodal, multicommodity transportation planning is addressed. A model is introduced, and an algorithm is described to solve the corresponding bilevel optimization problem. The algorithm is efficiently implemented by using strategic transportation analysis, an interactive-graphic transportation planning package designed for national and regional strategic analysis and planning of multimode, multiproduct freight transportation. Data from an actual application are used to characterize the performance of the proposed methodology. In conclusion, a number of generalizations and promising developments are presented.| Current library | Call number | Status | Date due | Barcode | |
