Applying FEATHERS for Travel Demand Analysis: Model Considerations

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

Activity-based models of travel demand have received considerable attention in transportation planning and forecasting over the last decades. FEATHERS (The Forecasting Evolutionary Activity-Travel of Households and their Environmental RepercussionS), developed by the Transportation Research Institute (IMOB) of Hasselt University, Belgium, is a micro-simulation framework particularly developed to facilitate the implementation of activity-based models for transport demand forecasting. In this paper, we focus on several model considerations when applying this framework. First, the way to apply FEATHERS on a more disaggregated geographical level is investigated, with the purpose of obtaining more detailed travel demand information. Next, to reduce the computation time when applying FEATHERS on a more detailed geographical level, an iteration approach is proposed to identify the minimum size of the study area needed. In addition, the effect of stochastic errors inherently included in the FEATHERS framework is investigated, and the concept of confidence intervals is applied to determine the minimum number of model runs needed to minimize this effect. In the application, the FEATHERS framework is used to investigate the potential impact of light rail initiatives on travel demand at a local network in Flanders, Belgium. In doing so, all the aforementioned model considerations are taken into account.
