This paper develops a number of Riemann solvers for a conserved higher-order traffic flow model, which are derived firstly by expressing its exact Riemann solver through that of the LWR model, and then by replacing the exact Riemann solver of the LWR model with the corresponding approximate Riemann solvers in the expression. Being applied to design a(More)
An extended optimal velocity traffic flow model on two lanes including a bus stop and a bus deceleration area is proposed. The fundamental diagram is classified into seven distinct traffic states with the variation of density. Two new traffic states are found. One of them shows that lane-changing occurs frequently whether in front of or behind the bus, the(More)
