摘　　要：建立在区域经济学分区理论基础上的四阶段法是各种交通量预测方法中精度最高、应用最广泛的预测方法,但其计算过程相对复杂,常常需要反复迭代计算才可得出正确结果。使用TransCAD软件进行四阶段法交通量预测,可大大减化计算过程,其内置可根据实际扩展的预测模型,使交通量预测结果更加准确。该文利用该软件对青海共和至结古高速公路工程可行性进行了交通量分析,指出了在使用TransCAD软件进行交通量预测时应该注意的问题。Four-stage method based on regional economic area theory is the most accurate and the most widely used forecasting methods in the variety of traffic volume,but its calculation is relatively complex and often requires iterative calculations.Four-stage traffic volume prediction method by use of TransCAD can greatly reduce the computing process and its prediction result is more accurate based on its built-in and the actual extended prediction model.The author describes the use method of the software through in...
