Data-Fusion Techniques in Hard Shoulder Monitoring System

This paper describes the development of a Hard Shoulder Monitoring System (HASMOS), capable of combining the data from the two independent sensor systems with the aim of improving overall system performance. The data-fusion algorithms that form the core of the system are described in detail, together with the development work being undertaken to bring the system from its initial proof-of-concept form to a deployable pilot system. Following comprises the trial of the system, using simulated data generated by a software model and real data obtained from off-road and on-road trials, and subsequent refinement of the system analysis of the trials.
