Aggregated Modeling of Urban Taxi Services

Models are an indispensable tool for decision makers when defining the principal policy measures of the taxi services, such as fleet size, fares or operational modes of the services within the city. Various models have been developed for calculating the variables that characterize the taxi services in urban regions. This paper presents an extensive review of the presented formulations for the modeling of taxi services in urban areas. The variables of the problem are identified and analyzed, presenting the different formulations proposed in the literature for each one of the three operational modes (hailing, stand and dispatching).
