Road traffic injuries and fatalities remain a major global concern, with the World Health Organization
(WHO) reporting 1.35 million deaths in 2016 in their Global Status Report on Road Safety 2018. These
incidents not only result in a significant loss of life but also have significant social and economic
consequences. To address this issue, several countries adopt best road safety practices to develop and
implement their own national road safety strategy with specific goals and targets, aimed at eliminating fatal
crashes and reducing serious injuries. The strategy is executed through a well-defined action plan that
includes a long-term program of proposed safety measures, which can be applied over a period of 10 years
or more. However, the absence of tools for controlling actions and monitoring road safety performance can
hinder the achievement of the strategic goals. It is therefore imperative to monitor the progress and impact
of implemented actions to evaluate the success of the road safety strategy and provide feedback to road
safety managers. These information can be used to make necessary timely adjustments in case of deviation
from the set targets. In light of the above, this study aims to provide a comprehensive overview of road
safety monitoring systems through a literature review. An automated initial search was performed using a
selected search string in the Web of Science database, covering papers on road safety management
published between January 2000 and July 2021. Out of the 290 candidate papers, 36 studies were selected
for further analysis after applying inclusion and exclusion criteria, based on titles, abstracts, and
conclusions. The data extracted from the selected studies was used to meet the study's objectives, which
were:
• Providing an overview of the papers carried out on road safety monitoring, including publication
year, channel and source, author type, and geographical distribution;
• Identifying the available research categories and tools for road safety monitoring;
• Classifying and categorizing the selected studies into different road safety models used.
This review reveals that most studies were carried out mainly as part of two research categories; (1) Solution
proposal category where the researchers develop new or improve an existing road safety monitoring
technique, and (2) Evaluation research category where the researchers conduct an evaluation of an
implemented technique in road safety monitoring systems.
The study presents and discusses then the various techniques, systems, or frameworks related to road safety
monitoring identified in the selected papers belonging to these two categories.
Finally, this overview of road safety monitoring systems can serve as a foundation for developing a data-
based framework for monitoring the success of road safety strategies implementation.
