Icy pavements can provide a risk to pedestrians in terms of slips and falls. Local authorities provide grit (salt and sand mix) for local volunteers to spread to assist in reducing ice on pavements. This report investigates the potential to instal fill level sensors in local community grit bins to assist the local authority with grit bin refill requirements. It sets that investigation in the context of the benefits of pavement gritting, and the policies for the provision and stocking of grit bins, both in Suffolk and in surrounding counties. This report then details research undertaken into the use of sensors for fill level monitoring, using both observational and experimental techniques. It pulls together this information in a business case assessment, and makes recommendations for grit bin stocking in Suffolk.
