One of the major problems large metropolitan areas have been facing is traffic congestion (saturation of the transportation network infrastructure). The problem’s cause is well-known: as demand gets higher, the infrastructure (roads, rails and so on) is unable to fulfil it, because of its limited capacity. The alternative to the permanent enlarging of the infrastructure is to make use of more e...

− In this paper a simple algorithm to detect an emergency vehicle’s siren using the linear prediction is presented. By measuring the means and variances of the reflection coefficients in a preselected number of successive frames, automatic detection of emergency vehicle’s siren is possible. It has been shown that only two coefficients are enough for successful detection. Due to the simplicity o...

In Indian four-lane express highway, millions of vehicles are travelling every day. Accidents are unfortunate and frequently occurring in these highways causing deaths, increase in death toll, and damage to infrastructure. A mechanism is required to avoid such road accidents at the maximum to reduce the death toll. An Emergency Situation Prediction Mechanism, a novel and proactive approach, is ...

Each year, thousands of people in developing countries die due to delayed medical response. A common complaint is that emergency vehicles respond late and when they reach the hospital, precious time is lost in understanding the patient trauma before the doctors can get to work. A large number of deaths can be prevented if medical services can be provided to the victims in time, which can happen...

Nowadays, the number of vehicles has increased exponentially, but the bedrock capacities of roads and transportation systems have not developed in an equivalent way to efficiently cope with the number of vehicles traveling on them. Due to this, road jamming and traffic correlated pollution have increased with the associated adverse societal and financial effect on different markets worldwide. A...

In this paper we develop a simulation model to evaluate a real-time Emergency Medical Service (EMS) vehicle response system that uses real-time travel time information and assists the emergency vehicle dispatchers in assigning response vehicles and guiding those vehicles through non-congested routes. Different response strategies are evaluated using this simulation model. These include the Firs...

Safety applications provided by Vehicular Ad Hoc Network is very crucial. The vehicles in the road form a network enabling the passengers with infotainment and security. Emergency messages can be disseminated in the VANET scenario for securing the lives of people by avoiding the situations like chain collisions. The main aim of such messages is to provide safety. So these messages should be gen...

VESPA (Vehicular Event Sharing with a mobile P2P Architecture) is a system designed for vehicles to share information in inter-vehicle ad-hoc networks. The originality of VESPA is to support any type of event (e.g., available parking spaces, accidents, emergency brakings, obstacles in the road, information relative to the coordination of vehicles in emergency situations, etc.) in the network. I...

Managing traffic in urban areas is a complex affair. The same becomes more challenging when one needs to take into account the prioritized movement of emergency vehicles along with the normal flow of traffic. Although, mechanisms have been proposed to model intelligent traffic management systems, a concentrated effort to facilitate the movement of emergency services amongst urban traffic is yet...
