Among the agencies operating public transport in the ZMVM, only Metrobus, ECOBICI and the suburban railway are collecting and making use of the data provided by smart cards for planning and optimisation. In many cases, data collection and several modelling exercises (e.g. origin-destination for certain areas of the city, estimation of modal shift and C02 emission mitigation, demand forecasting, environmental impact assessments) are carried out with the aim of implementing specific projects (underground line extensions, BRT corridors, bike lanes). However, information is currently neither used nor verified between agencies or gathered into an integrated model that could guide overall mobility planning. Poor long-term modelling and forecasting capacity will limit the ZMVM’s long-term vision for mobility planning.
