    Abstract

    Rapid mobilization of emergency vehicles in the urban or rural road network presents a high probability of collisions and other related hazards to other drivers. Yet uninterrupted high speeds of the emergency vehicles through traffic are imperative for the successful patient transfer or negotiation of fire and flood emergencies. The utilisation of contemporary emergency vehicle sirens as an early warning system has proved inefficient and in some cases unsafe as the localisation characteristics of siren patterns, combined with ambient noise, has a detrimental effect on the average driver's ability to spatially define the position of the incoming emergency vehicle. This paper examines the inherent issues in the localisation of the incoming emergency vehicle audible warning systems and suggests a prototype system for faster localisation propensity of the incoming vehicle.
