WIRELESS NETWORK RESILIENCE ESTIMATION FOR BUS SAFETY

Bus network operators recognise that improved security and safety on buses means more passengers leaving their cars and moving to public transport.

Wireless Network Resilience Estimation for Bus Safety

This project uses selective ray tracing to model the radio frequency electromagnetic environment around and inside the bus to estimate the signal strength for different radio frequency networks at any time. This is essential as the bus operator wants to guarantee that the bandwidth and signal strength are sufficient for transmission of telemetry and video data when a security/crime incident occurs on a bus.

In the long term this will act as a deterrent to criminals due to success in detection and conviction.

The work presented is part of the ISIS (Integrated Sensor Information System) programme involving an industrial consortium of over 8 partners. The system integrates computer simulation, Ordnance Survey Map information, and measurement validation to provide a detailed model to the bus operator.
