Road safety is of utmost concern to many sectors of society. It is now common to find both public and private organizations and nongovernmental organizations (NGOs) implementing actions to prevent road collisions and reduce their severity. However, little is known about the effectiveness of unconventional actions for the improvement of road safety. The literature suggests the use of performance indicators to monitor the results of actions and help in the decision-making process. The objective of this paper is to show how performance assessment can be inserted into the context of road safety by proposing road safety indicators for an NGO operating in Brazil. This NGO promotes activities related to road safety education, particularly for young people. This work can be used as an aid for setting up indicators for similar road safety organizations operating in other countries.
