Effective incident management requires accurate prediction of incident duration. In this paper, Classification and Regression Tree (CART), CHAID and Exhaustive CHAID is employed to model the incident duration. All 65000 incident records from Beijing Transportation Management Bureau are used for model establishment and another 8000 records for validation. The average relative error of the CART model...
Along with the spatial resolution of remote sensing images getting higher and higher, the complex structure in the simple objects becomes obvious, which makes the classification algorithms based on pixels begin losing their advantages. The huge number of clastic plaques contained in the classification results not only have no clear meanings, but also disturb the post-process. The phenomenon is much...
Integration of spectrum, texture and shape information, evidence theory is introduced to land covers classification of high-resolution images, and an object-oriented land covers classification method of high-resolution images based on Dempster-Shafer evidence theory is proposed. Firstly, for image objects, four kinds of indexes are selected as attributes to discriminate different land cover types,...
