This paper presents a macroscopic traffic simulation constructed through hydrodynamic model. The purpose of the simulation is to describe the fluctuation of traffic density distribution all over the network consisted of signalized intersections. Links are divided into segments. Traffic density of each segment is updated by time scanning procedure. By using the simulation, relationship between delay and offset, and relationship between delay and common cycle length were obtained. The traffic density distribution near the signalized intersection was also obtained and the influence of q-k model, especially triangle-shaped and trapezoid-shaped q-k model was examined. Furthermore, the simulation was applied to the optimization of offset. GA was used to optimize the offset.
