摘要： The traffic equilibrium problem (TEP) is an essential module in transportation planning. This paper studies an extended TEP version, i.e. the path-specific traffic equilibrium problem (PS-TEP), which has many applications in the real world. Due to inherent path interactions, the PS-TEP cannot be formulated as an optimization model but can be formulated as a variational inequality model. The corresponding user equilibrium conditions are characterized by the equal and minimum generalized path cost, which in turn can be expressed as a function of actual path costs and path-specific disutility. To interpret the PS-TEP as an extension of the TEP, an augmented network representation that includes a basic network (incurred actual path costs) and an additional virtual network (incurred path-specific disutility) is proposed. A path-based solution algorithm, called the gradient projection method, is modified for demonstration. Four path-specific cost schemes of the path-specific disutility are used for elaboration using the same framework. The numerical examples show that the user equilibrium conditions are fully satisfied. Future research should address the corresponding efficient solution algorithms. 出版者： Taylor & Francis 出版日期： 2014-05-19 出處： Journal of the Chinese Institute of Engineers, 2014-05, Vol.37 (4), p.461-468 版權： 2013 The Chinese Institute of Engineers 2013 識別號： ISSN: 0253-3839 識別號： EISSN: 2158-7299 識別號： DOI: 10.1080/02533839.2013.815008
