Major commuting corridors in metropolitan areas generally comprise multiple transportation modes for commuters, such as transit (subways or buses), private vehicles, or park-and-ride combinations. During the morning peak hour, the commuters would choose one of the available transportation modes to travel through the corridors from rural/suburban living areas to urban working areas. This paper introduces a concept of transportation serviceability to evaluate a transportation mode’s service status in a specific link, route, road, or network during a certain period. The serviceability can be measured by the possibility that travelers choose a specific type of transportation service at a certain travel cost. The commuters’ modal-choice possibilities are calculated using a stochastic equilibrium model based on general travel cost. The modeling results illustrate how transportation serviceability is influenced by background traffic flow in a corridor, value of comfort for railway mode, and parking fee distribution.
► The concept of transportation serviceability is introduced to evaluate a transportation mode’s service status. ► Modal choice possibilities are calculated using a stochastic equilibrium model based on generalized travel costs. ► Transportation serviceability can be influenced by background traffic, value of comfort, and parking fee distribution. ► Serviceability analysis results are discussed from the policy perspective.
