How to Estimate, Take Into Account, and Improve Travel Time Reliability in Transportation Networks

摘要: Many urban areas suffer from traffic congestion. Intuitively, it may seem that a road expansion (e.g., the opening of new road) should always improve conditions. However, in reality, can actually worsen It is therefore extremely important before we start project, first predict effect this project on Traditional approach to prediction based assumption for any time day, know exact amount needs go each origin city zone A every other destination B (these values form an OD-matrix), and capacity segment. Under assumption, known efficient algorithms produce equilibrium flows. In unpredictably change due weather conditions, accidents, etc. Drivers take uncertainty into account when planning their trips: e.g., if driver does not want be late, he or she follow slower route but with guaranteed arrival instead (on average) faster unpredictable one. We must simulations. paper, describe account.
