Applying Haddon Matrix for Evaluation of Road Crash Victims in Delhi, India

An adapted taxonomy and framework for monitoring road safety strategies: a case study of Morocco

Traditional approaches to monitoring road safety have primarily focused on measuring outcomes such as the number of fatalities and injuries. While effective in capturing overall trends, this macroscopic approach often overlooks the underlying causes of unsafe conditions. Recognizing these limitations, many countries now embrace a safe system-based approach, which emphasizes a holistic view of road safety, considering various elements and their interactions. In response to this shift, this study introduces a five-step framework designed to provide comprehensive coverage and tailored assistance in selecting and utilizing appropriate Road Safety Indicators (RSIs) for more effective performance monitoring. The framework integrates a novel RSIs taxonomy aligned with critical elements of the safe system. It also incorporates an MCDA-based approach to account for decision-makers' preferences when selecting suitable RSIs. A case study demonstrates the practical application of the proposed steps, including the identification, classification, selection, and development of descriptive sheets for each selected RSI, as well as the continuous updating of the RSIs set. The findings offered valuable insights into the commonly used indicators in international road safety reports, while also revealing the limitations of currents metrics and data in fully capturing critical elements and hierarchical level within the road safety management system.

Risk factors associated with quad bike crashes: a protocol for systematic review of observational studies

INTRODUCTION

Quad bikes are four-wheeled vehicles, driven off-road on uneven terrains by farmers for work or young adults for leisure. Quad bike accidental crashes result mostly due to the unique ecosystem of uneven terrain, where these unstable vehicles are commonly driven, in addition to numerous distinctive sociodemographic characteristics related to drivers. This is a protocol for a systematic review of observational studies from all geographical regions and demographic groups in the world to summarise the common risk factors relating to quad bike crashes.

METHODS AND ANALYSIS

A comprehensive search for the literature on quad bike crashes and related injuries will be conducted in six electronic databases: PubMed, Embase, Scopus, Web of Science, IEEE and PsycINFO. Proquest Dissertation and Thesis, OpenGrey and BASE will be searched for grey literature. Five researchers will be involved in the screening, and the review of full text articles, using the inclusion and exclusion criteria. Disagreements between reviewers will be resolved by discourse. Three researchers will help resolving conflicts that may arise during the screening process and will resolve eventual conflicts identified in the process with the help of the systematic review software 'Covidence' for automatic deduplication and blinded screening. Information on crashes leading to injuries and death, target population characteristics and risk factors involved will be extracted from eligible articles in addition to the assessment of the quality of the researched articles.

ETHICS AND DISSEMINATION

Since this is a systematic review of published literature, a formal ethical approval is not needed. Results of the review will be disseminated through peer-reviewed publications, conference presentations and reports to the concerned authorities.

Contributing Factors Affecting the Severity of Metro Escalator Injuries in the Guangzhou Metro, China

Urban rail transit has become one of the indispensable modes of public transportation in large cities. Escalators are ubiquitous in metro stations, as passengers typically use escalators when entering or leaving a metro station. Thus, escalators have become an accident-prone location. To develop suitable prevention strategies, it is necessary to understand the risk factors that affect the severity of escalator accidents. This study analyzed 967 escalator passenger accidents that occurred in the Guangzhou Metro from 2013 to 2015. The Haddon matrix was used to evaluate the interaction of humans, escalators, and environmental factors before, during, and after accidents. Then, the contributing factors associated with the severity levels were determined based on chi-square tests. Passengers aged 66 years and older are more vulnerable to serious injuries (p < 0.001), and previous health conditions are significantly related to the severity of the passenger’s injuries (p = 0.002). The weather conditions (rainy days) are also significantly related to the severity of escalator accident injuries (p = 0.039), and injured people with head injuries are at greater risk of being severely injured (p < 0.001). The analysis results of these risk factors can provide theoretical support for the metro operators to develop reasonable and effective preventive measures to reduce the escalator risk.

Assessing the Effects of the Road Surface and Weather Conditions on Road Safety

When transport is analysed for its safe delivery the focus is mainly on assessing the safety of roads and the risk of undesired events. These include road accidents, an occurrence which is relatively rare and random. Randomness means that accidents depend on several factors which are partly deterministic and partly. The authors conducted an assessment of how weather conditions affect the risk of an accident due to the factor’s significant contribution to road accidents. This case involves a combination of two sources of hazard: external conditions in the form of the weather which are beyond the driver’s control and anthropotechnical factors that address vehicle condition and driver behaviour controlled by the driver.
