dc.description.abstract | Propõe-se um modelo de tráfego rodoviário macroscópico semi contínuo baseado
no “Cell Transmission Model”. O modelo incorpora o limite de velocidade como
parâmetro variável. Além disso, é proposto o emprego de algoritmos de controle ótimo
para a resolução de problemas de otimização dinâmica que contenham o modelo
proposto na forma de Equações Diferenciais Algébricas (DAEs). Testes em diferentes
cenários de simulação, com condições de tráfego adversas, mostram que o sistema
de controle é capaz de impedir ou, pelo menos, reduzir os efeitos prejudiciais do
congestionamento no sistema de tráfego. | |
dc.description.abstract | A semi-continuous model for macroscopic traffic in freeways is proposed, based on Cell
Transmission Model and other second-order continuous models. The proposed model
embraces the speed limit as the manipulated variable. Moreover, optimal control algorithms
are applied in order to solve the dynamic optimization problem in the form of Differential
Algebraic Equations (DAEs). Tests in different simulation scenarios with different adverse
traffic conditions show that the controlled system is capable of avoiding, or at least
decreasing, the harmful effects of traffic jams, traffic congestion and stop and go waves,
commonly seen in traffic systems. | |
