term	models path choice path overlap model construct	path overlap variable	An additive measure of similarity between paths. In road-based path-choice models, this is often the distance of the shared links. In passenger-based path-choice models, this could include considerations for shared-routes, similar-routes, on/off stations, traversed stations, traverse distance and more. If the overlap variable is an indicator variable (𝛿), then it can be 1 or 0; if it distance or cost, then it is a continuous variable.	la is the path overlap variable for link a; Li is the sum of the path overlap variable over all legs that make up path alternative i.	.	model construct	.
