TY - JOUR PY - 2014// TI - Optimization of bus routing strategies for evacuation JO - Journal of advanced transportation A1 - Zheng, Hong SP - 734 EP - 749 VL - 48 IS - 7 N2 - Efficient transportation of evacuees during an emergency has long been recognized as a challenging issue. This paper investigates emergency evacuation strategies that rely on public transit, where buses run continuously, rather than fixed route, based upon the spatial and temporal information of evacuee needs. We formulated an optimal bus operating strategy that minimizes the exposed casualty time rather than operational cost, as a deterministic mixed-integer program, and investigated the solution algorithm. A Lagrangian-relaxation-based solution algorithm was developed for the proposed model. Numerical experiments with different problem sizes were conducted to evaluate the method.
