Constructing personalized transportation networks in multi-state supernetworks: a heuristic approach

For accessibility analysis, an integrated view encompassing the networks for public and private transport modes as well as the activity programs of travellers is essential. In earlier research, the supernetwork has been put forward by the authors as a suitable technique to model the system in such an integrated fashion. An essential part of a supernetwork model for multi-modal and multi-activity travel planning is the personalized transportation network. This is an under researched topic in the academic community. This paper attempts to develop a heuristic approach to construct personalized transportation networks for an individual’s activity program. In this approach, the personalized network consists of two types of network extractions from the original transportation system, namely the public transport network (PTN) and the private vehicle network (PVN). PTN is composed of selected public transport connections based on an individual’s preferences related to walking distance, transfer times, fare and time cost, etc.; whereas the PVN is constructed on the Constructing Personalized Transportation Networks In Multi-State Supernetworks LIAO, Feixiong; ARENTZE, Theo; TIMMERMANS, Harry 12 WCTR, July 11-15, 2010 – Lisbon, Portugal 2 basis of optimal routes of the considered private vehicles in a hierarchical road network based on multi-attribute link costs functions. Two cases are presented to illustrate that the PTN and PVN can represent an individual’s attributes and perceptions appropriately and be applied in large-scale applications for analyzing land-use and transport systems.
