Abstract: Landscape scholars and information scientists are often interested in 
the structure of knowledge and the relationships of subject areas to each 
other. This study examines the latent structure of the transportation citation 
universe as evidence concerning how connected or disjointed areas of 
knowledge are to each other. Multivariate statistical analysis techniques were 
performed on citation data from 16 years of transportation articles in 
Landscape Journal, Landscape Research, Landscape and Urban Planning. The 
study produced 101 source articles and 1351 citation articles, arranged in 31 
Library of Congress subject areas. Principal component analysis revealed 
thirteen significant dimensions. The results suggest that the universe is 
complex, yet disjointed and reinforce the notion that investigations in 
transportation related to landscape are fragmented and disconnected.
