Facilitating Emergency Response Vehicles’ Movement Through a Road Segment in a Connected Vehicle Environment

Sequential Optimization of an Emergency Response Vehicle’s Intra-Link Movement in a Partially Connected Vehicle Environment

“…In this paper, the initial approach of Hannoun et al is extended to optimize the ERV passage over larger distances (3). The approach assumes the presence of a centralized computing server that preprocesses the collected data (positions, speeds, and deceleration capabilities of connected vehicles), runs the ILP, and post-processes and stores the ILP output.…”

“…Hannoun et al presented a mathematical program to facilitate ERV passage along a transportation link of predefined length by relying on vehicular communications (3). The integer linear program (ILP) identifies the fastest ERV intra-link path along with the ERV's maneuvering instructions based on downstream information.…”

“…The ILP also assigns to each downstream non-ERV a specific stopping position along the link. In Hannoun et al, the proposed system is limited to short links because of computation time, and so is only effective if activated by the ERV driver needing assistance over a short distance (3). However, the ERV's driver may request extended assistance, especially in congested urban transportation networks.…”

“…Although the connected vehicle environment is rapidly evolving, the deployment of its hardware and software components remains challenging. The market penetration rate of connected vehicles will remain low in the near-term future, which prevents the work in Hannoun et al-in which all vehicles are connected-from being directly applicable in the near future (3,4).…”

Wireless recommendations for Internet of vehicles: Recent advances, challenges, and opportunities

“…IoV can bring some fundamental changes to urban emergency response and accident management. In the IoV, when an emergency occurs, for example, car accidents, dangerous road conditions, the connected cars, or roadside units can automatically send real-time data via IoV about the emergency along with the location information to the emergency management system [20,21] . The emergency management system can automatically respond to this (for example, send a warning to nearby vehicles) or make a request for human emergency team involvement (for example, human emergency team will ask police and ambulances to handle the case).…”
