KNOWLEDGE OF ROAD TRAFFIC COLLISIONS BASED ON IN-DEPTH RESEARCH METHODOLOGY

AIDAMAGE PRACTICAL REAL-WORLD USE

The practical application of AiDamage software from theoretical principles requires a thorough understanding of the mathematics involved and how they translate into crash damage energy dissipation. This module intends to demonstrate the practical limitations and best practise for a confident result using the AiDamage program.

AIDAMAGE THE THEORY

The conservation of energy and basic physics’ principles allow mathematical algorithms to transfer crush damage into an amount of energy absorbed in an impact. This can be presented as an energy equivalent change in velocity. This module proposes to give delegates the ability to calculate velocity change from crash damage using basic mathematics.

COLLISION DEFORMATION CLASSIFICATION

The classification of impact damage for research purposes has been coded systematically using an SAE regulated protocol for many years. The current system has been in place since 1984 and allows comparative coding and recording of all crash damage on road vehicles and encourages users to assess crash damage from a more scientific view point. Used as a search tool it enables crash data to be sorted and analysed easily by the type and severity of impact. It is also key to inputting the correct data into programs as AiDamage and PC crash. This module teaches the use of the system and give a practical exercise coding real damage demonstrating the potential difficulties in the field.

INTRUSION DEFORMATION CLASSIFICATION

Crash investigators have struggled for many years to accurately and easily assess and electronically code vehicle intrusion in crash damaged vehicles. The Intrusion Deformation Classification (I.D.C.) is a method of assessing and coding intrusion for use by all those involved in vehicle collision related work and although it can be easily learnt it is designed for those who are already competent using Collision Deformation Classification (C.D.C.). I.D.C. is a 8 digit alpha-numeric code directly related to, and compatible with, Collision Deformation Classification SAE J224 mar80 (C.D.C.) currently in use for the coding of external damage.

FORENSIC EVIDENCE AND CORRELATION

Systematic examination of a vehicle interior can reveal much about what occurred during the final few milliseconds of a crash. With in-depth knowledge of what happens in most common instances it enables the investigator to focus their attention on the most probable and be able to predict injury outcomes. Thorough assessment of vehicle to occupant interaction will enable assessment of seatbelt use, probable seat position for occupants and much more.

INJURY CORRELATION & COLLISION TYPES

The Cooperative Crash Injury Study has over 25 years of occupant injury data correlated to the respective damage sustained by the vehicles involved. With an in-depth knowledge of the causes of injury from various impact scenarios it is possible to interpolate likely injury outcomes from the type and severity of an impact. This information can be vital for those first on scene of an road traffic incident and critical time can be saved assessing the scene and calling for the appropriate response. This module will give delegates confidence to assess a scene more effectively and potentially save vital time on those most in need of attention.

SECONDARY SAFETY EXAMINATION

Most vehicles on the roads today are fitted with technology designed to mitigate occupant injury during a collision. This module will describe the common equipment, it’s function and it’s working parameters. Devises such as pretensioned seatbelts, airbags and side impact protection systems have all been the subject of miss-information and urban myths and this module will present only the facts about these systems.

SEATBELTS HISTORY AND NON USE

There have been huge changes in the technology of seatbelts from their early canvas webbing start to the highly technical materials used in currently systems. This module will describe why seatbelts are as they are today and how they are now an integral part of the vehicle’s safety system and what happens when car occupants have collisions without wearing them. It will also look to the future developments of these systems and how intelligent belt systems will adapt for their occupants and the crashes they are experiencing.

STEERING WHEEL AIRBAGS

With a typical window of 200 milliseconds, occupant/airbag timing is critical. This module will allow identification of this interaction, how it has worked with the other restraint systems, the type of airbag fitted and its deployment characteristics. It will cover multi stage airbags and explain how to identify an out of position occupant and the effect this has on airbag interaction and injury causation. The module will discuss the history of steering wheel hub airbags and the electronics/engineering behind them. This can all help provide an investigator with evidence of injury’s sustained, seating position and more.

SIDE AIRBAGS

Side or lateral airbags have very varied designs. Rapid intrusion, following a side impact, allows very little time for deployment of these designs. This module will explain the form and function of lateral airbag location, shape and venting. Why seat or door? Why tube or curtain? It will also look at lateral airbag effectiveness, injury mitigation and occasional injury causation.

MOTORCYCLE V CAR OVERVIEW

Motorcyclists are still an over represented crash statistic, the popularity of motorcycling as both a leisure activity and a daily transport are increasing. Motorcycles and cars interact in ways not represented in standard crash tests. So real world investigation provides essential data. This module will explore the crash profile for both car and motorcycle and how examination of occupant and vehicle contacts can provide vital information. It explains calculating speeds from crush and the difficulties involved. It will also cover the science behind motion camouflage and driver perceptions which can contribute to the ‘looked but did not see’ scenario.

INVESTIGATING ROLLOVERS

Often complex events, rollovers can be difficult to analyse and reconstruct. Identifying airborne phases, initial grounding, rollover initiation and final rest are vital in piecing together the physical evidence. This module includes in depth assessment of forensic evidence, the SAE rollover classification system and a study of the occupant kinematics and injury outcomes unique to rollover events. From ‘Trip overs’ to ‘Bounce overs’ . Number of rolls to ejection routes, you will gain a thorough knowledge, enabling you to come to confident conclusions.

FUTURE TECHNOLOGY

It is essential that crash investigation be fully up to date with new and emerging technology. Lane departure, smart cruise, active braking and steering are standard and optional fitment on newer vehicles. Additionally hybrid, fuel cell and hydrogen technologies are finding their way into production vehicles. These technologies will bring with them new challenges for crash investigators. This module covers the technologies themselves, identifying their fitment and their potential within a crash.

Effective training

Effective training has to be grounded in thorough scientific research, be targeted at the correct level for the participants, be interesting and enjoyable, be understood and able to be retained, to have a useful practical application and encourage the thirst for further knowledge.
Rob Newton Associate’s training programmes are created using up-to-date, first-hand knowledge of the subject and are based on on-going scientific research.

The modular format would consist of; formal presentation with identifiable learning outcomes; workshop, discussion or group activity or practical activity; participant assessment; further reading and/or exercise to embed knowledge.

Certificate of attendance outlining the learning objectives and hours CPD awarded. Further study and activity can also be assessed.
