Abstract

In public transport, crowding is one of the variables that is likely to influence the decisions of the choice makers. Crowding has become a subject of concern in metropolitan areas, triggering passenger travel behavior, such as shifting from public to private modes of transport, changing routes or departure times, etc. Hence, there is a need to understand the effect of crowding in public transport and its influence on the behavior of travelers. Therefore, this review investigates essential factors (e.g., crowding representation, crowding measurement, modeling framework, etc.) after reviewing the 40 screened studies on the valuation of crowding in public transport. The paper’s findings show that the passenger perception towards crowding is different for varying levels of crowding, modes of transport, study areas, data types, different modeling frameworks, and the underlying distribution of the attribute parameters. A meta-analysis is performed to show the influence of explanatory variables affecting the value of the time multiplier. A net-salary-based city classification is used to make the results transferable. Lastly, this work provides a direction for the selection of the crowding representation, measure, and valuation for future studies. Further, several research gaps are identified for the model formulation, valuation, crowding at different locations, non-linearity, etc.
