In order to measure the results of the renewal of all or part of the fleet of a bus network, an information system based on an array of indicators feeding into a dashboard must be implemented. The extent of the renewal determines the scope of the measure: one route, a group of route, the network (in the event of a full renewal). In addition to monitoring the project in the strictest sense of the term, particularly with regard to operations, it may be worth – as part of a more ambitious goal – looking for the overall effects on mobility in the case of a major renewal.
But in any case, this raises the question of the capacity of the organising authority and the operator (all the more so, when multiple operators are involved) to collect the data, process them, analyse them and draw conclusions from them to be used for subsequent projects.
