摘要
通过对吉林地区国民经济发展趋势的分析，得出了规划年度国民经济主要指标的预测结果。用三种方法建立了预测公路客、货运输量的数学模型，从而确定了其预测结果。并运用单纯形方法对各规划年度的公路网等级结构进行了优化，通过综合分析得出客运需求高于货运的结论。
This paper gets predicting results for national economy main target in annual planning through the trend analysis of national economy for Jilin area. The mathematics model for predicting the quantity of road passenger and freight transport are set with three kinds of methods. The predicting result is affirmed. The grade structure of a road network in annual planning is optimized with the simplex method. Conclusions are reached through synthetic analysis.
