Abstract in Portuguese
Desenvolve-se, neste trabalho, um modelo de simulação estocástica para o sistema de transporte por táxi com viagens exclusivas. Basicamente, o modelo simula a geração da demanda pelo serviço e as formas alternativas de oferta: ponto privativo, ponto livre e rádio táxi. A validação do modelo é realizada através da comparação entre o sistema de táxi observado na cidade de Bauru (SP) e o sistema simulado através da aplicação do modelo. A comparação é feita para a alternativa de oferta com pontos privativos, a única existente na cidade. Os resultados indicam que o modelo de simulação proposto reproduz bem a demanda e a oferta de viagens por táxi em cidades de porte médio. Apresenta-se, além disso, uma análise comparativa das simulações realizadas para as duas outras alternativas fictícias de operação na cidade de Bauru (SP); os resultados destas, quando comparados aos da situação existente, mostram uma significativa economia nos custos variáveis. Conclui-se que o modelo pode constituir-se num instrumento de análise e avaliação das diferentes políticas de operação de táxi e apontar a mais adequada para uma determinada cidade de porte médio.

Abstract in English
In this work, a stochastic simulation model for the exclusive-ride taxi system is developed. The model simulates the demand generation for taxi service and the alternative forms of service supply: private pickup point, free pickup point, and radiotaxi. The model validation is carried out by comparing the taxi system observed in Bauru (SP) with that simulated using data set collected in it. The comparison is concerning to the operation with private pickup point because in Bauru there is only this type of operation. The results indicate that the proposed simulation model reproduces adequately the taxi demand and supply in medium sized cities. It is also presented a comparative analysis between existent system and other operation systems simulated. The analysis shows that a significative cost saving is obtained if the operation system is changed in Bauru. It is concluded that the proposed model may constitute an important tool to analyze and evaluate the different operational policy and indicate the most adequate one for the medium sized cities.
