由路段流量反推OD矩阵,路段流量的调查结果往往被认定为是一个确定数。但是实际生活中,任何一条路段的流量值都是波动的,将其固定为某个数值势必造成反推出的OD对的不精确性。本文将路段流量视为合理范围内的区间数,运用不确定规划技术,计算出各OD对的合理区间。并以一个简单路网为例,验证该方法是可行的。 The OD matrix of road traffic is inversely estimated, and the result of the survey of road traffic is often regarded as a certain number. However, in real life, the flow value of any road section fluctuates. Fixing it to a certain value will inevitably lead to inaccuracies in the OD pair being pushed back. In this paper, the section traffic is regarded as the interval number within a reasonable range, and the uncertain interval planning technique is used to calculate the reasonable interval of each OD pair. Taking a simple road network as an example, it is feasible to verify this method.
