Ambulance response modeling using a modified speed-density exponential model

Individual ambulance velocity and response time to a single incident. Existing lane based models have been modified by formulating mathematically emergency vehicle capability and behavior in the UK. The model is applied to calculate travel time. The velocity is simulated for different scenario of city environments. The response time of the ambulance is then calculated using a Dijkstra algorithm. The model is shown to provide the means to differentiate ambulance travel time compared to non emergency road users.
