Emergency Vehicle Routing in Urban Road Networks with Multistakeholder Cooperation

The lack of multistakeholder cooperation is one the main challenges faced by emergency medical services (EMS). Especially in ambulance routing process, inactive traffic operators fail to provide coordination prioritize ambulance, while ignoring choice hospitals will lead inevitable patient transfer between hospitals. To efficient decision support for EMS, this paper considers daily problems a network with high spatial resolution which two advanced technologies are introduced: prehospital screening that provides injury diagnosis and lane preclearing ensures predefined driving speed ambulances. Three different types ambulances used transport offer first aid patients based on screened results. manage fleet properly, mixed-integer linear programming (MIP) model proposed assign vehicles injured plan routes shortest travel time. A semisoft time window constraint incorporated reflect late arrival penalty onsite at Because high-quality EMS responds call seconds, real-world case Shenzhen, China, presented validate computational performance commercial solver: general algebraic modeling system (GAMS). In study, we further analyzed effect stakeholders’ involvement, like operators. This information proves efficiency participation routing.
