於此篇文章中我們主要探討並研究一個關於交通流的非線性雙曲型守恆定律。此交通流的模型包含著一個能夠表示車道變換之車輛的強度的參數。這模型可以重寫成一個含有源項的守恆定律的形式（亦即此守恆定律方程式之等號右側帶有非零項）。此文章亦會展示幾種不同案例的車道變換強度之數值計算結果。 In this thesis we study a nonlinear hyperbolic balance law arise from traffic flow. The model of traffic flow consists of a parameter representing the intensity of lane-changing of vehicles. The model is rewritten as a balance law with source terms. The numerical results are given for different cases of lane-changing intensities.
