摘要
本文把交通出行（运输）距离作为随机变量，证明了此随机变量服从负指数分布，又证明了负指数分布参数等于该地区平均运距的倒数。进而在以上理论证明的基础上，提出了交通规划中ＯＤ表计算的简易实用方法。最后，又利用了中、美、日诸国的交通统计数据，使用本文方法，作了验证计算，证明了理论计算结果完全符合实际值。从而使作为交通规划核心的ＯＤ表计算进展到理论化、简易化、实用化的阶段。
Traffic trip(transportation)distance proposed as a random variable in thispaper is proved to abide by a negative exponential distribution law,and the negative eponen-tial distribution factor is also proved to be equal to the reciprocal of average transportationdistance of this area.Accordingly a simple and practical method of computing OD table intraffic planning is proposed.Finally the proposed method is verified by traffic statistical dataof China,America,and Japan,etc.the results are quite closed to the actual values,showingthat the simplification of the OD table computation is feasible.
