The stochastic nature of emergency service requests and the unavailability of emergency vehicles when requested to serve demands are critical issues in constructing valid models representing real life emergency medical service (EMS) systems. We consider an EMS system design problem with stochastic demand and locate the emergency response facilities and vehicles in order to ensure target levels ...

Emergency vehicles (ambulances, police cars and fire trucks) are deployed for rescuing people in an emergency. Crash statistics for Alberta, Canada indicate that more than 300 road traffic accidents every year involve at least one emergency vehicle. The aim of this study is to identify the factors that may have an influence on the probability of injury in crashes involving emergency vehicles in...

This paper presents STEID, a spatio-temporal emergency information dissemination protocol for vehicular networks. Its main goal is to quickly disseminate traffic alerts about accidents or congestions to every car that passes through an emergency zone during the lifetime of the emergency. To achieve this goal, we propose a hybrid network architecture consisting of WiFi clusters connected through...

In this paper an advancement on the SICURO Research Project relating to the design of path choice models for emergency vehicles is proposed. In particular, with respect to the previous work in which the procedures to be planned and activated in emergency conditions were defined in order to allow the evacuation of weak users (the disabled, senior citizens, etc.) from the area affected by a disas...

Optimization of emergency vehicles routing is a complicated system engineering that is influenced by multitudinous factors. To improve efficiency of emergency rescuing, the optimization model of emergency vehicles routing have also been built, And on that basis, and optimization algorithm have also been put forward based on simulated annealing algorithm. Finally, in order to testify validity, o...

BACKGROUND Response time is viewed as a key performance indicator in most emergency medical services (EMS) systems. OBJECTIVE To determine the effect of increased emergency vehicle numbers on response time performance for priority 1 incidents in an urban EMS system in Cape Town, South Africa, using discrete-event computer simulation. METHOD A simulation model was created, based on input dat...

A simple model for a string of vehicles is constructed. The model explicitly accounts for the possibility of repeated collisions between the vehicles in the string. Based on the model a notion of safety is formulated for the string. Necessary and su cient conditions are presented that specify when a string of vehicles is safe while performing a simple emergency deceleration maneuver where all v...

This issue of Crash•Stats focuses on updated information in the National Highway Traffic Safety Administration’s Not-in-Traffic Surveillance (NiTS) system regarding injuries involving passenger vehicles that occur in non-crash incidents. As part of the NiTS system, NHTSA has joined with the Consumer Product Safety Commission (CPSC) to collect information on non-crash injuries involving passenge...
