Understanding and improving temporary road sign stability

Temporary road signage is used throughout networks to regulate traffic and provide warnings users. Wind other factors induce frequent falling of temporary are a major safety concern that needs be addressed. The main aim this paper was gain an understanding sign stability in the presence passing trains investigate possibility stabilising through appropriate design modifications. Simulations experimental trials were carried out assess current signs industry. This analysis Ansys Fluent simulate fluid dynamics order infer stability. A field trial performed Western Australia’s Pilbara Region using modified developed based on outcome simulation. findings from simulations showed unstable highly prone wind induced failure. suggest train transit at 100 km/h capable inducing approximately 8 m/s velocity proximity sign, which greater than permissible for rigid with no leg mobility. Field remained stable 1.2 m edge line although it still over closer distances.
