山西省高速公路网布局探讨

综合考虑山西经济发展水平、产业布局特点、未来经济发展战略、路网发育形态等诸多因素，采用交通区位法和节点重要度法相结合，对山西省高速公路布局进行探讨。采用交通区位法得出山西省高速公路的大致走向，再通过节点重要度法计算出路线重要度最大树，最后将两种方法得到的结果叠加。在此基础上，对路线进行优化，得出了山西省高速公路最终布局结果，即“人字骨架、九横九环”，总里程4050km．该结果已被山西省国民经济“十一五”发展规划采纳实施，目前已建成高速公路1752km。

Distribution of Expressway Network in Shanxi Province

Through considering the level of economic development,the characteristics of industrial layout,future economic development strategies,development of the road network and many other factors,and combining traffic location method with node important degree method,the distribution of expressway network in Shanxi Province is discussed.The general direction of expressway in Shanxi is obtained by traffic location method,the largest tree for line important degree is calculated by node important degree method.On this basis,line optimization is conducted,and the final distribution result of expressway network is given,that is,"herringbone skeleton,central 9 cross 9",total length of 4056 km.This result has been adopted and implemented by " 11th five-year plan"of Shanxi national economy and 1752 km of expressway has been built up.
