Abstract
The costs borne by road infrastructure authorities for managing and maintaining road devices such as safety barriers may be very high. This has prompted the need for identifying and analysing in detail all factors that influence the costs of safety barriers throughout their service life. To meet that need, the authors used international experience and field data collected under the LifeRoSE project to define the cost structure and, as a next step, to analyse factors that are relevant to the costs actually incurred.
Highlights
When designers and investors decide on a specific type of safety barrier, they will usually consider the technical and economic aspects
A basic tool for road infrastructure management [2] is to calculate the life cycle costs (LCC) of a road device which looks at the expenditure incurred at each stage of safety barrier life cycle: planning, design, construction, operation and decommissioning
It is assumed that once collected and classified, the safety barrier cost data will form a basis for building a method for safety barrier life cycle cost assessment
Summary
When designers and investors decide on a specific type of safety barrier, they will usually consider the technical and economic aspects (the initial costs to buy). This leaves road infrastructure authorities with a major problem of having to pay high costs of safety barrier maintenance and operation (this includes maintenance and repairs) [1]. When developing a method for life cycle cost assessment it is important to define the structure of costs to be borne throughout the entire life cycle. It is assumed that once collected and classified, the safety barrier cost data will form a basis for building a method for safety barrier life cycle cost assessment
