1、先通过原单位乘以发生发生特征得到出行发生量。如表1・1表1-1出行发生量小区编号1234合计1811.25152.510082.81675.817722.321216.85610.511866.41128.619822.331886.047694.414268.81915.225764.444811.28358.56588.4222317981.151115.42702.26115.21128.611061.461994.215297.210064.6547.227903.271385.812526.38899.81265.424077.3合计9220.

2、6457341.6678869883.8144332再通过原单位乘以吸引特征得到出行吸引量。如表1-2表1-2岀行吸引量小区编号12合计114402.568985.723388.26217748.4813977.131725.5832259221753.344345.348051.213298.621349.8511322.8823942.235265.08614133.7613316.327450.0675468.1618691.224159.36合计93719.04113964.4207683.4由于发生与吸弓I总量不相平衡。修正吸弓I原单位。得到新

3、表1・3.(P117)因为要使所以可推导得到D)=2338&26*144332/27683.4=16253.94D2=31725.58*144332/27683.4=22048.060^=44345.3*144332/27683.4=30818.28D沪21349.8*144332/27683.4=14837.29Ds=35265.08*144332/27683.4=24507.88£=27450.06*144332/27683.4=19076.74D7=24159.36*144332/27683.4=16789.83表1-3出行吸引量小区编号12合计调

4、整后为114402.568985.723388.2616253.94217748.4813977.131725.5822048.0632259221753.344345.330818.2848051.213298.621349.814837.29511322.8823942.235265.0824507.88614133.7613316.327450.0619076.7475468.1618691.224159.3616789.83合计93719.04113964.4207683.4144332如此就得到了出行发生与吸引量。归结成未来出行发生与吸引交通量

5、，如表14所示。表1-4将來的发生与吸引交通量1234567合计(U)117722.3219822.3325764.44417981.1511061.4627903.2724077.3合计(V)16253.942204&0630818.2814837.2924507.8819076.7416789.83144332解毕二.利用平均增长系数法求交通分布；由材料易得出现状OD表为下图1・5所示现状OD1234567合计(D)11400110033009802000108074010600280011901210110035909802180110503590
