SG_ERSAF_S09 202000 Certificate in Road Safety Audit and Engineering

This module provides the learner with advanced and specified learning and knowledge relating to road safety engineering and collision analysis so that collision data collection and statistical analysis of collisions can inform the learner of the procedures required to assess the causes of accidents and determine potential engineering solutions. Traffic conflicts and management areas are also explored. The module addresses road scheme design and speed management for urban and rural roads with an emphasis on the safety of vulnerable road users and non-motorised users. 

This module also provides the learner with advanced learning and knowledge relating to the road safety audit process for urban and rural road schemes in Ireland. The requirements and procedures for the auditing of schemes at various stages from route selection to operation is a key focus of the module. 

A review is undertaken of the TII standards for Road Safety Audit, and other TII standards based on the requirements of the Road Infrastructure Safety Management EU Directive, including Road Safety Impact Assessments. The implications for practical auditing of the safety of routes, designs, construction and operation are investigated by means of theory lectures and individual assignments. The communication of safety problems and potential solutions between the audit team and design team at each of the specified stages are also explored.


Learning Outcomes

On completion of this module the learner will/should be able to;


Critique and interpret the roles and responsibilities of organisations in Ireland relating to road safety and the requirements and implications of the implementation of the EU Road Infrastructure Safety Management Directive 2008/96/EC


Investigate the causes of road collisions and evaluate the efficacy of relevant data collection methodologies and data analysis techniques.


Critique current road safety engineering processes, conflicts, remedial options, accident investigation, and economic analysis methodologies.


Appreciate the requirements for rural and urban road network design, speed management, and the specification of facilities for the general safety and protection of vulnerable and non-motorised users.


Appraise the roles and responsibilities associated with current Irish road safety and quality auditing processes for both audit and design teams.


Propose potential solutions based on risk analysis and hazard identification for both rural and urban road schemes at specified stages of road planning, design, construction and operation.


Communicate effectively and critically the outcomes of both design and construction stage audits to the design team and other representatives of the employer and contractor where appropriate, and evaluate designer responses based on best practice technical and operational knowledge.


Report critically on the findings of road safety and urban road quality audits at the specified stages using acquired knowledge and expertise pertaining to selected scheme case studies..

Teaching and Learning Strategies

The teaching and learning strategy is based on the provision of live and recorded on-line lectures, Moodle (VLE) resources, and independent learning that incorporates elements of enquiry and project-based learning for individual practical and project work and reporting of findings.

Module Assessment Strategies

The assessment incorporates a blend of final written examination and practical assignments. The learner must achieve a grade of 40% or higher in order to achieve a pass in this module.

Repeat Assessments

The learner must undertake repeat final written examination and/or continuous assessment project work depending on the particular failed element(s) to achieve an overall pass grade.

In recognition of the importance of road safety as a major health issue, the World Health Organization has declared 2011-2021 the Decade of Safety Action. Several countries in Europe, North America, and Asia have been successful in reducing fatalities and injuries due to road traffic crashes. However, many low-income countries continue to experience high rates of traffic fatalities and injuries. Transport Planning and Traffic Safety: Making Cities, Roads, and Vehicles Safer offers a source book for road safety training courses as well as an introductory textbook for graduate-level courses on road safety taught in engineering institutes. It brings together the international experiences and lessons learned from countries which have been successful in reducing traffic crashes and their applicability in low-income countries. The content is based on lectures delivered during an international course on transportation planning and traffic safety, sponsored annually by the Transportation Research and Injury Prevention Programme (TRIPP) at the Indian Institute of Technology, Delhi. The book is interdisciplinary and aimed at professionalstraffic and road engineers, vehicle designers, law enforcers, and transport planners. The authors examine trends in performance of OECD countries and highlight the public health and systems approach of traffic safety with the vulnerable road user in focus. Topics include land use (transportation planning, mobility, and safety), safety education and legislation, accident analysis, road safety research, human tolerance to injury, vehicle design, safety in construction zones, safety in urban areas, traffic calming, public transportation, safety laws and policies, and pre-hospital care of the injured.

This book explains the systematic process for checking the safety of new road schemes. Since publishing the first edition in 2000 there have been many changes in the area of road safety auditing, such as the introduction of the new Road Safety Audit Standard produced by the Highways Agency which has resulted in changes to the way Road Safety Audits are carried out. Amongst other things this book addresses the increase in the number of Home Zones and Safer Routes to School projects, the concepts of shared space and self-explaining roads, the idea of passive safety, the new standard on road restraints published by the Highways Agency and the issues raised by the introduction of the Manual for Streets - including the new challenges for Road Safety Auditors.
