Abstract:

Few previous works integrated both uncertainty and environment disruption into the traffic network design problem (NDP), despite the critical impact of these two factors in sustainable transportation planning. This study aims to address this gap. First, the mathematical framework of the strategic user equilibrium (StrUE) traffic assignment under volatility of both total travel demand and link capacity is analyzed, which reflects disequilibrium observed in traffic networks. Second, the authors incorporate the StrUE traffic assignment model into a network design project and propose a multiobjective bi-level program for the sustainable NDP. Two objective functions are formulated, which are respectively to minimize the expected total system travel time and minimize the expected total system off-gas emissions in the uncertainty-based NDP. Third, in the algorithmic framework, the authors develop two tailored solution methods – one is an exact algorithm and the other one is a metaheuristic method based on a genetic algorithm. Finally, systematic evaluation of the performance of the proposed approach is conducted on three different test networks. The results highlight that ignoring uncertainty considerations can result in sub-optimal design solutions in terms of expected network performance in long-term transportation planning decisions. The results also report that the two objectives, to minimize system-level travel time and vehicle emission, are conflicting for certain uncertainty-based design scenarios.
