Performance assessment of road equipment: state of the art

Download
Sven-Olof Lundkvist

In the future, if new mobile instruments will be developed condition assessments of road equipment might become valuable tools for deciding when and where maintenance is needed most.

The conclusion of this survey is that condition assessment of road equipment, such as measurement of luminance and illuminance of road lighting and measurement of retroreflectivity of road signs are rare. This fact is to a large extent due to the lack of suitable instruments.

In order to maintain the performance of road equipment, it is important to take correct action at correct time. This means that repair or renewal of the equipment in question must be carried out when the performance has reached the lowest acceptable end user service level (EUSL). The time of this occurrence should be based on a management model or a condition assessment, which involves physical measurement and/or visual inspection.

This report shows the state of the art regarding condition assessment of road equipment. It deals with monitoring methods, maintenance measures and acceptable end user service levels in seven European countries: Belgium, Croatia, Denmark, Germany, the Netherlands, Sweden and UK. The work has been limited to the more important types of road equipment: road markings, road studs, delineator posts, fixed traffic signs, variable message signs (VMS) and road lighting.
