The purpose of this report is to identify the current state-of-the-art in Europe with regards to roadside design guidelines. The analysis is limited to official national documents and does not include all the policies that are practiced at national and regional levels. All the information presented in this report is derived from the national documents (Appendix A). It should be noted that the use of the word design implies the prescribed layout of the roadside environment (placement of light posts, geometry of slopes, installations of road restraint systems. The term design does not imply the specification of system components (guardrail metal thickness, bolt sizes on break-away poles, etc.). The report is divided into six chapters that represent the main issues to be addressed in the analysis and design of roadsides for the purpose of improving safety. The first two chapters describe the concepts of the Safety Zone and the Recovery Zone. These describe the area beside the road travel lanes that are subject to the roadside design process. The third section describes the types of common obstacles / hazards that must be identified in the roadside. The remaining chapters cover the specifications of road restraint systems, as they are reported in the existing guidelines.
