Abstract:

The research carrier of existing route-swapping models is the single mode traffic network. These models cannot describe travelers’route- swapping behaviors on actual multi- modal network. For this, this study suggests utilizing two methods, i.e., proportional expansion and absolute expansion, to capture travel- ers’cost perception psychology towards different travel modes on multi-modal network. The corresponding multi-modal route-swapping dynamic (MRSD) is developed. It is founded that: MRSD can avoid over swap- ping and maintain solution variance; The stationary path flow state of MRSD is equivalent to the multi-mod- al user equilibrium; at stationary path flow state, those used routes within the same mode have the same and minimum actual cost, while cost perception barrier exists between two utilized routes within different modes; All the solutions of MRSD are bounded and converge to the multi-modal user equilibrium.
