Abstract: This paper compares three different types of network paths which are used in stochastic traffic assignment, and presents a new method for implementing stochastic assignment excluding all cyclic flows. The paper further redefines the concept of efficient paths and develops a heuristic to create efficient paths by utilizing the iterative process of solving deterministic user-equilibrium assignment. Numerical results are presented to validate the proposed approaches.
