采用区间数描述出行者出行信息的不确定性,提出了多属性出行方式决策模型。基于互补判断矩阵的最小平方法计算不同出行方式的权重,建立了离差最大化模型计算特性变量的权重,进而获得出行方式的组合权重,并根据调查数据筛选小汽车出行和公交出行的样本进行模型有效性检验。分析结果表明:当小汽车出行权重达到0.65以上时,出行者往往采用小汽车出行;当公交车出行权重达到0.68以上,往往采用公交车出行。可见,该模型可有效模拟出行者出行方式选择。
Using the interval number to describe the uncertainty of traveler’s travel information, a multi-attribute travel mode decision-making model is proposed. Based on the least squares method of complementary judgment matrix, the weights of different modes of travel are calculated, the model of variance maximization is established to calculate the weight of the characteristic variables, and then the combined weight of the modes of travel is obtained, and samples of car trips and bus trips are screened according to the survey data Model validity test. The results show that when the weight of the car reaches above 0.65, the traveler often travels by car. When the weight of the bus reaches more than 0.68, the bus often travels by bus. Can be seen, the model can effectively simulate the traveler’s travel options.
