On Dial Assignment and Choice Probabilities

CHENG Lin, WANG Wei

2002, 2(3): 29-32 .

Abstract ( )

PDF (217KB) ( )

In the travel assignment models, the volume of the traffic flow passing a route, link and node and size is proportional to the probability of choosing that particular route, link and node in OD matrix. This paper summarizes Dial assignment model and its properties that are associated with the attributes with the attributes of a logic choice model. On the basis of weight concepts and probability principles, the probabilities of choosing route, link and node have been derived as analytical formulas with node-pair weights.

Application Fuzzy Clustering Methodin the Highway
Traffic Black-Spot Cause of Formation Analysis

XIAO Shen, GUO Xiu-cheng, XU Jian-dong

2002, 2(3): 40-43 .

Abstract ( )

PDF (201KB) ( )

This text demarcates the space of black-spot cause of formation by using the fuzzy c-demarcation space method; and the fuzzy demarcation matrix and the clustering center of each character index of the causes of formation are determined using fuzzy clustering method of ISODATA and then the clustering analysis of the black-spot causes of formation is proceeded. The effect of fuzzy clustering is assessed by using demarcation quotiety and the average fuzzy entropy of the demarcation.
