I. Introduction
The population of cities is growing, and research demonstrates that, in the next decades, 66% of the world population will reside in cities [1]. Hence, we should prepare for all the changes that will occur inside the cities which in parallel will affect its transportation system (TS). TSs are created relative to the environment in which they are executing their function, and this exposes them to research and improvements. Inside the TS, we have the buses' system which runs on a scheduled plan. Buses work in both cities and suburbs. The buses running inside the cities may be more complicated to plan or/and to control than the others due to the variability within the urban mobility. For instance, the study in [2], which was conducted using transit data from several regions of greater Paris, showed that the evolution of passengers frequency in the metro stations has increased from 2013 to 2015 in the west part of Paris. This increase was explained by the establishment of several industries in that region. This latter explains that a bus transport planning may be affected by any changes that occur during time inside its environment such as new infrastructures. This requires a frequent update of the system.
