A Bathtub Model of Downtown Traffic Congestion and Its Application in KISII Town

Abstract

Traffic congestion in surface transport causes serious economical and environmental problems. In urban areas more especially during the rush hours. A person living in a major town will appreciate that congestion is a significant issue. In this project bathtub traffic flow model was studied to  show how congestion can be managed in our major towns in Kenya. The partial differential equations with appropriate initial and boundary conditions governing this problem were solved using the finite difference method. The parameters affecting dynamic velocity and traffic flow density namely; were investigated. The numerical results were presented graphically. It was found from this project that the results were consistent with traffic flow behavior. This model was tested in Kisii CBD and may be extended to other downtown areas.
