Generalized model for linear referencing in transportation

The Generalized Model for Linear Referencing is proposed as a theoretical basis for representing and translating linear locations. It separates the concepts of the linear element which is being measured and the linear method of measurement. It formalizes the concept of a distance expression as the measurement which is made. A location expression is then introduced as the combination of these three concepts. Comprised of mappings between location expressions, a generalized set of translation expressions are formalized as the method of converting between measurement methods and linear elements.
