Abstract. This paper presents adjustments and validation of a model for the process of passenger boarding and alighting of
BRT (Bus Rapid Transport) and express bus systems. Such models are of fundamental importance for the implementation
of strategies to control the operation of those systems, which allow for quality and efficiency gains in the service. First, a
generalized disjunctive programming model is presented in order to adapt a bus headway control formulation according to
the number of onboard passengers. Later, as a way to improve the model, real data were collected from the boarding/alighting
times of passengers in the Trunk line 10 system in the city of Blumenau, Brazil. These data were used in a two-stage fuzzy
regression to take into account the uncertainties associated with the dwell time of the passengers. The actual data collected
were used in simulations of the enhanced bus headway control system, showing that even in the presence of disturbances,
the system can still operate properly without bunching.

1. Introduction
Mass public transport, and more generally urban
mobility, has been a topic of constant discussion and
mobilization of society, which also draws attention in
Brazil. Among the main topics discussed, besides the
costs of transport tariffs, we can cite the quality and
efficiency of the services. A negative factor observed
in a large number of bus-based public transportation
systems is the deviation of the schedule and/or bus
headway (tendency of bunching). These deviations
increase the waiting time of users and the costs of
operating the transportation system [1–3].
A solution to the problem of real time operating of
bus public transport systems is the implementation

of control strategies for their operation. Given the
need for differentiated quality of express bus and
BRT (Bus Rapid Transport) systems, the application
of real-time operation strategies in these systems is of
paramount importance, highlighting the bus holding
strategies at stops [4–7].
These real-time strategies make use of prediction
models for boarding and alighting times of passen-
gers at stops and/or terminals and stations. However,
those commonly used models can be overly simplis-
tic, implying a representation that does not match the
actual observed behavior or is too complex for real-
time applications. In a developed country scenario,
with buses that do not operate crowded and with
adequate road and station infrastructure, these sim-
plifications typically used may not be significant. In
the case of underdeveloped countries, in the everyday
reality of many Brazilian cities, the real behavior of
