Uncertainty of the od matrix's estimation in urban public transport

The key of the planning of public transport systems is the accurate prediction of the traffic load which requires a well-functioning assignment method and reliable passenger data (i.e. time-dependent OD matrix). The paper two years ago at TRA2014 was started with this idea. Since that time the procedure was improved and real network test was performed. Based on the experiences of the real network tests several new improvements were implemented. This paper shows the newest results with the previously described method and search for connection between network structure and certainty together with sample size. (C) 2016 The Authors.
