This paper investigates the network connectivity and efficiency of international airline alliances, and conceptually applies the shortcuts of small-world networks to analyze alliance routes. Based on travel time, mobility and accessibility models are formulated to evaluate the effects of...

High-speed rail (HSR) lines are usually planned to serve corridors with existing conventional rail (CR) lines, since these corridors typically have large markets concentrated around major cities. This paper formulates a new analytical model to estimate market shares of HSR and CR in a...

A walking distance of approximately a quarter mile is normally used as an estimate of willingness to walk when planning a pedestrian-related infrastructure. However, there are variations in walking distance across pedestrian environments, yet there is scant empirical literature on the subject....

The authors formulate a model integrating households' residential-mode choice and residential distribution in a metropolitan area with surface streets and rail transit networks. The model was constructed to describe transportation -- residential land-use interaction by means of continuous...
