1. Introduction 1. Introduction

Extensive corrosive damage of lighting poles may lead to unexpected falls of poles, which may cause dangerous injuries and accidents. The Roch “Infrastrukturprojekt Straßenbeleuchtung 2000” (Infrastructure Project: Street Lighting 2000) study on the structural stability of pole systems, which is representative on a Germany-wide scale, found that 3.3% of all poles pose a hazard (Roch Services GmbH, (2019)). The standard prevention is regular replacement of lighting poles (e.g. Prague standard in Czech Republic is replacement of each pole every 15 years).
