“…That RF module [3] has a limited range and focuses primarily on one sensor, probably resulting in a single point of failure. M. U. Ghazi et al [4] Framework can save lives by allowing emergency responders to respond to accident scenes more quickly. The track felons who try to escape the scene of an accident are by which they were involved.…”

In an enormous population, people make vehicles for their needs, leading to heavy traffic. Every day, thousands of people die in road accidents across the world, creating a global hazard. In the existing system, when an accident occurs, information only is sending to emergency services through GSM, but there is no prospect for an insurance claim. This research paper describes the detection of the crash using a piezoelectric device by the observation of vibration caused by fatal crashes. There are two types of accidents: major accidents and minor accidents. These will be determined by establishing new crash pressure threshold values. Depending on the nature of the accident, official announcements can decide to make to eitherlocal emergency services and vehicle insurance companies, or both vehicle insurance and health insurance companies, as well as local emergency services.

In Vehicular Adhoc Networks (VANETs), disseminating Emergency Messages (EMs) to a maximum number of vehicles with low latency and low packet loss is critical for road safety. However, avoiding the broadcast storm and dealing with large-scale dissemination of EMs in urban VANETs, particularly at intersections, are the challenging tasks. The problems become even more challenging in a dense network. We propose an Effective Emergency Message Dissemination Scheme (EEMDS) for urban VANETs. The scheme is based on our mobility metrics to avoid communication overhead and to maintain a stable cluster structure. Every vehicle takes into account its direction angle and path loss factor for selecting a suitable cluster head. Moreover, we introduce estimated link stability to choose a suitable relay vehicle that reduces the number of rebroadcasts and communication congestion in the network. Simulation results show that EEMDS provides an acceptable end-to-end delay, information coverage, and packet delivery ratio compared to the eminent EM dissemination schemes.

“…Different approaches are used for this purpose. In this context, VANET (Vehicular Ad-hoc Network) can be utilized [8], [9], in which every moving vehicle acts as a node. On occurrence of accident, the alert messages are communicated via RF (Radio Frequency) module [10].…”

With population growth, the demand for vehicles has increased tremendously, which has created an alarming situation in terms of traffic hazards and road accidents. The road accidents percentage is growing exponentially and so are the fatalities caused due to accidents. However, the primary cause of the increased rate of fatalities is due to the delay in emergency services. Many lives could be saved with efficient rescue services. The delay happens due to traffic congestion or unstable communication to the medical units. The implementation of automatic road accident detection systems to provide timely aid is crucial. Many solutions have been proposed in the literature for automatic accident detection .The techniques include crash prediction using smartphones, vehicular ad-hoc networks, GPS/GSM based systems, and various machine learning techniques. With such high rates of deaths associated with road accidents, road safety is the most critical sector that demands significant exploration. In this paper, we present a critical analysis of various existing methodologies used for predicting and preventing road accidents, highlighting their strengths, limitations, and challenges that need to be addressed to ensure road safety and save valuable lives.
