Modelagem da operação de uma parada de ônibus com o uso da microssimulação de tráfego

Abstract

Traffic microsimulation is an important tool for studying the operation of public transportation. This type of transport needs to be well studied in viewof the influence it has on people's lives and society. Thus, the objective of this work is to model the BRT: North Shopping Station, located in Fortaleza, Ceará, Brazil, using VISSIM traffic microscopic simulator. Firstly, field observations were made to collect the information about the surroundings of the BRT station under study, the bus lines operating at the BRT station, and the vehicles that are used. Subsequently, data were collected on days considered typical of service in order to obtain, among other parameters, the dwell time, the headways and the number of passengers boarding and alighting for each bus line. After that, the BRT station under analysis was simulated with data from one of the collection days by three methods provided by VISSIM: time distribution, advanced passenger model and Viswalk. The model simulated the operation of September 5th, and model was validated with data collected on September 14th, with the target performance measure being the bus dwell times. It was possible to evaluate the operation of the BRT stop under study from the means of the dwell times and the headways of the lines, obtaining values that are below what is usually found in the literature for the time in analysis, showing that the operation is being well performed. With the validated model, it was possible to verify the limitations of its use and to estimate the operation in future scenarios. Finally, the functionality of the traffic microsimulation was assessed for the analysis, planning, and operation of the transportation system, concluding that the user should be aware of the limitations, assumptions, advantages and disadvantages of the models created and the cost inherent to this type of tool.
