The model used in this study is assumed to be a finite and circular road. MacCormack's scheme was applied for the numerical scheme. Different initial conditions are investigated. Furthermore, a source term is introduced into the continuity equation in order to handle an interchange on the road. The congestion has been formed by an initial perturbation or an on-ramp. The results have indicated that once a traffic jam has been formed, the spatial and temporal profiles become to be similar regardless of initial conditions or existence of a junction. The traffic jam moves backward in the process of formation a traffic jam, on the other hand, moves forward in the process of clearing a traffic jam.}, pages = {71--81}, title = {Numerical simulation of vehicular traffic with a junction on a circular road}, volume = {57}, year = {2007} }
