A Reliability-Based Dynamic Network Design Approach

This paper presents a formulation of a reliability-based road network design problem with a dynamic user equilibrium constraint. Reliability is introduced in both design level and lower level equilibrium level. A long-term user equilibrium is achieved. Travelers take into account day-to-day variability of travel times caused by stochastic over-day capacities and make their departure time and route choice decisions in order to minimize their long term future trip costs which is composed of expected travel time, expected schedule delay of arriving early or late, and travel time reliability. The number of lanes of each road segment is the design variable. A genetic algorithm (GA) is utilized to solve the combinatorial optimization problem. This paper shows the feasibility of solving a reliability-based road network design problem subject to dynamic user equilibrium with departure time choice modeling.
