应用最小二乘法进行公路网规划中社会经济及运输量预测

公路建设事业与社会经济发展趋势密切相关,对社会经济的准确预测,可以指导交通量的预测,从而进一步协助公路网规划工作;反过来,公路建设事业的蓬勃发展亦可以促进社会经济的发展.应用数学计算方法中的最小二乘拟合曲(直)线法,试图通过建立各种数学模型,对社会经济的各项发展指标和运输量进行预测,从而对公路网的规划工作起到参考作用.

Using Method of Least Squares to Forecast Social Economy and Traffic Volume

The highway construction has a close relation to the development of social economy.The exact forecast the social economy can be guide to traffic volume forecast.In further,the planning of highway network is under the guidance of traffic volume forecast.In contrast the development of highway can promote the progress of social economy.This paper tries to set up various mathematic model,the method we used is method of least squares,in order to forecast all kinds of social economy criterion and traffic volume.At last using all these forecast will help the work of planning of highway network.
