Accident Management System Based on Vehicular Network for an Intelligent Transportation System in Urban Environments

Abstract

As cities across the world grow and the mobility of populations increases, there has also been a corresponding increase in the number of vehicles on roads. The result of this has been a proliferation of challenges for authorities with regard to road traffic management. A consequence of this has been congestion of traffic, more accidents, and pollution. Accidents are a still major cause of death, despite the development of sophisticated systems for traffic management and other technologies linked with vehicles. Hence, it is necessary that a common system for accident management is developed. For instance, traffic congestion in most urban areas can be alleviated by the real-time planning of routes. However, the designing of an efficient route planning algorithm to attain a globally optimal vehicle control is still a challenge that needs to be solved, especially when the unique preferences of drivers are considered. The aim of this paper is to establish an accident management system that makes use of vehicular ad hoc networks coupled with systems that employ cellular technology in public transport. This system ensures the possibility of real-time communication among vehicles, ambulances, hospitals, roadside units, and central servers. In addition, the accident management system is able to lessen the amount of time required to alert an ambulance that it is required at an accident scene by using a multihop optimal forwarding algorithm. Moreover, an optimal route planning algorithm (ORPA) is proposed in this system to improve the aggregate spatial use of a road network, at the same time bringing down the travel cost of operating a vehicle. This can reduce the incidence of vehicles being stuck on congested roads. Simulations are performed to evaluate ORPA, and the results are compared with existing algorithms. The evaluation results provided evidence that ORPA outperformed others in terms of average ambulance speed and travelling time. Finally, our system makes it easier for ambulance to quickly make their way through traffic congestion so that the chance of saving lives is increased.

A Novel Internet of Things-Enabled Accident Detection and Reporting System for Smart City Environments

“…The economic and social benefits are clear; a recent World Bank study finds that “welfare benefits equivalent to 6 percent to 32 percent of the national GDP can be realized from reducing 50 percent of road deaths and injuries over a period of 24 years” [17]. In the field of intelligent transport systems, the main focus is on information obtained in real time and decision-making on the basis of this information [18].…”

RSSI and Public Key Infrastructure based Secure Communication in Autonomous Vehicular Networks

“…When the proposed solution is used, it will compare the ratio of RSSI at time, t 1 and t 2 to receive the packet. If (6) Then there is no attack and the network is secure for communication with other nodes. Based on Figure 8, the graph shows the percentage of packet overheads against the number of nodes with and without RSSI localization during and attack.…”

“…Alongside other technology that has emerged during this time, the idea of autonomous car can be categorized as an excellent idea, however there are still draw back happened. As the autonomous car is wireless, it depends on a system for exchanging data or information between other vehicles in order to avoid collision on the road [5], [6]. The use of wireless sensor network (WSN) system creates an opportunity to the attacker such as hacker to attack the car system and function of the autonomous car.…”

Emergency Messages Dissemination Challenges Through Connected Vehicles for Efficient Intelligent Transportation Systems: A Review

“…In infrastructure-based data dissemination, message is broadcasted to all nodes in its range using some sort of infrastructure such as RSU, ITL, ICU, sensors, central servers and cellular networks (46)(47)(48). Some infrastructure-based schemes are focused on providing the complete solution in terms of accident prevention, prediction of accident, congestion management and rerouting of traffic after accident.…”
