Some typical difficulties faced in the daily operation of a bus system can be caused by unexpected traffic conditions in
cases where buses are mixed with other vehicles in most routes, which increases travel time uncertainty and delays at
bus stops. In cases of severe congestion, it may be advisable to propose the construction of exclusive bus-ways and specialized
infrastructure for fare collection outside of buses or traffic light optimization to improve bus circulation. The development
of a tool that is able to provide a diagnosis of bus speed is useful for planners and operators to make decisions regarding
the implementation of major projects and management measures. The analysis can be performed at different disaggregation
levels, starting from a global picture of the situation and moving to a detailed description of a specific bus route over a specific
segment of interest.
