The crash killed two passengers, while a third was killed after being run over on the ground by an emergency response vehicle. 这起空难导致两名乘客丧生,还有一名乘客在地面上被应急车辆(ERV)碾过导致死亡。
In order to improve the emergency response of freeway, an optimization model for emergency vehicle dispatching was established by integer programming. 为改善高速公路突发事件的响应效率,利用整数规划,建立了应急车辆(ERV)优化调度模型。
