Abstract
In road safety, as in most other fields, efficiency is an important criterion in political and professional decision making. Efficiency Assessment Tools (EATs) like Cost Benefit Analysis and Cost Effectiveness Analysis are available to help choose the policy which gives the highest return on investments. However, policies and decisions are often based on other grounds than effectiveness and efficiency. This study, Workpackage 3 of ROSEBUD (Road Safety and Environmental Cost-Benefit and Cost-Effectiveness Analysis for Use in Decision-making), looked at 11 individual barriers that were reason for not using EATs. This report presents some practical solutions to overcome these barriers, and to improve the use of EATs.
