Exploring inattention and distraction in the SafetyNet accident causation database

The SafetyNet Accident Causation Database was formulated as part of the SafetyNet Integrated Project. Data were collected in 6 European countries using ‘on-scene’ and ‘nearly on-scene’ crash investigation methods. 32% of crashes recorded in the Database, involved at least one driver, rider or pedestrian, which had been assigned the SNACS codes ‘Inattention’ and/or ‘Distraction’. 212 of the drivers were assigned ‘Distraction’ and 140 drivers were given the code ‘Inattention’. Distraction and Inattention often leads to missed observations and ‘Timing’ or ‘Direction’ critical events. In addition, the type of distraction and inattention differs according to the crash type

Identifying the causes of road crashes in Europe

This research applies a recently developed model of accident causation, developed to investigate industrial accidents, to a specially gathered sample of 997 crashes investigated in-depth in 6 countries. Based on the work of Hollnagel the model considers a collision to be a consequence of a breakdown in the interaction between road users, vehicles and the organisation of the traffic environment. 54% of road users experienced interpretation errors while 44% made observation errors and 37% planning errors. In contrast to other studies only 11% of drivers were distracted and 8% inattentive. There was remarkably little variation in these errors between the main road user types. The application of the model to future in-depth crash studies offers the opportunity to identify new measures to improve safety and to mitigate the social impact of collisions. Examples given include the potential value of co-driver advisory technologies to reduce observation errors and predictive technologies to avoid conflicting interactions between road users

Single-vehicle collisions in Europe: analysis using real-world and crash-test data

A large proportion of European road casualties result when a vehicle leaves the main carriageway, often impacting roadside obstacles. As part of the EC-funded project, RISER (Roadside Infrastructure for Safer European Roads), a number of activities were undertaken to collate the type of data which is needed to understand the frequency and severity of real world crash situations and relate this to crash test data mandated in the EU. Accident data was collected and used to create a statistical database and a detailed database exclusively for single vehicle 'run-off the road' collisions on major rural (not urban) roads, simulation software was used to further understand impacts with roadside structures and an inventory of crash test data was collected for impacts with objects such as poles and safety barriers . The combination of real world accident data, simulations and crash test data has provided a unique insight into the characteristics of single vehicle collisions, helping us to understand them better and make recommendations for consideration when drafting design guidelines. This information is crucial for those involved in the design and evaluation of the roadside environment

A European fatal crash database

A lack of representative European accident data to aid the development of safety policy, regulation and technological advancement is a major obstacle in the European Union. Data are needed to assess the performance of road and vehicle safety and is also needed to support the development of further actions by stakeholders. This short-paper describes the process of developing a data collection and analysis system designed to partly fill these gaps. A project team with members from 7 countries was set up to devise appropriate variable lists to collect fatal crash data under the following topic levels: accident, road environment, vehicle, and road user, using retrospective detailed police reports (n=1,300). The typical level of detail recorded was a minimum of 150 variables for each accident. The project will enable multidisciplinary information on the circumstances of fatal crashes to be interpreted to provide information on a range of causal factors and events surrounding the collisions

Recommendations for establishing Pan European transparent and independent road accident investigations

A set of recommendations for pan-European transparent and independent road accident investigations has been developed by the SafetyNet project. The aim of these recommendations is to pave the way for future EU scale accident investigation activities by setting out the necessary steps for establishing safety oriented road accident investigations in Member States. This can be seen as the start of the process for establishing road accident investigations throughout Europe which operate according to a common methodology. The recommendations propose a European Safety Oriented Road Accident Investigation Programme which sets out the procedures that need to be put in place to investigate a sample of every day road accidents. They address four sets of issues; institutional addressing the characteristics of the programme; operational describing the conditions under which data is collected; data storage and protection; and reports, countermeasures and the dissemination of data

The development of a European fatal accident database

A lack of representative European accident data to aid the development of safety policy, regulation and technological advancement is a major obstacle in the European Union. Data are needed to assess the performance of road and vehicle safety and is also needed to support the development of further actions by stakeholders. A recent analysis conducted by the European Transport Safety Council identified that there was no single system in place that could meet all of the needs and that there were major gaps including indepth crash causation information. This paper describes the process of developing a data collection and analysis system designed to partly fill these gaps. A project team with members from 7 countries was set up to devise appropriate variable lists to collect fatal crash data under the following topic levels: accident, road environment, vehicle, and road user, using retrospective detailed police reports (n=1,300).

The project will enable multidisciplinary information on the circumstances of fatal crashes to be interpreted to provide information on a range of causal factors and events surrounding the collisions. This has major applications in the areas of active safety systems, infrastructure and road safety, as well as for tailoring behavioural interventions

Proposing a framework for pan European transparent and independent road accident investigation

Unlike the rail, civil aviation and maritime transport modes, there is currently no standard process for investigating road accidents within Europe. There is, therefore, a wide range of road accident investigation procedures and protocols in place across Europe. However, as countries work towards meeting both their own road safety targets and those set by the European Commission, it may be that existing investigation practices are no longer suited to facilitating the decision making processes of road safety policymakers or practitioners. SafetyNet is a European Commission supported project, which is building a European Road Safety Observatory to facilitate the formulation of road safety policy in the European Union. Work package 4 of SafetyNet is developing recommendations for a Transparent and Independent pan-European approach to road accident investigation. These recommendations propose the establishment of an independent body for undertaking transparent and independent accident investigations where necessary, or the implementation of these investigations in existing national safety orientated accident investigation activities, in each of the EU Member States. This body would gather and manage accident investigation data and use this data to further progress road safety within the EU. To define the framework in which this body might operate, ‘Best practice’ from existing investigative organisations across Europe was examined in order to produce a set of draft recommendations which focused on four categories of issues: 1. Institutional, referring to the structure and functioning of the body responsible for road safety investigations; 2. Operational, detailing how the body carries out investigations; 3. Data, addressing issues surrounding the storage, retrieval and analysis of data generated by investigations; and 4. Development of Countermeasures, dealing with how investigation conclusions should be presented, used and disseminated. A consultation exercise was then undertaken in order to gather the expert opinion of European road safety stakeholders and to further develop the recommended framework. This highlighted a number of key questions about the Draft Recommendations including: • Is the proposed level of transparency and independence appropriate for road accident investigations? • Is one type of investigative activity appropriate for all types of accidents ranging from the most severe or ‘major’ accidents to the large number of more minor accidents that occur everyday? The major conclusion was that a ‘one size fits all’ approach is not appropriate for the investigation of road accidents and therefore multiple sets of recommendations are required. This paper discusses how the four categories of recommendations combine to form a framework where the data gathered during road accident investigations can be used to develop road accident countermeasures which will assist in casualty reduction throughout Europe

The development of a multidisciplinary system to understand causal factors in road crashes

The persistent lack of crash causation data to help inform and monitor road and vehicle safety policy is a major obstacle. Data are needed to assess the performance of road and vehicle safety stakeholders and is needed to support the development of further actions. A recent analysis conducted by the European Transport Safety Council identified that there was no single system in place that could meet all of the needs and that there were major gaps including in-depth crash causation information. This paper describes the process of developing a data collection and analysis system designed to fill these gaps. A project team with members from 7 countries was set up to devise appropriate variable lists to collect crash causation information under the following topic levels: accident, road environment, vehicle, and road user, using two quite different sets of resources: retrospective detailed police reports (n=1300) and prospective, independent, on-scene accident research investigations (n=1000). Data categorisation and human factors analysis methods based on Cognitive Reliability and Error Analysis Method (Hollnagel, 1998) were developed to enable the causal factors to be recorded, linked and understood. A harmonised, prospective “on-scene” method for recording the root causes and critical events of road crashes was developed. Where appropriate, this includes interviewing road users in collaboration with more routine accident investigation techniques. The typical level of detail recorded is a minimum of 150 variables for each accident. The project will enable multidisciplinary information on the circumstances of crashes to be interpreted to provide information on the causal factors. This has major applications in the areas of active safety systems, infrastructure and road safety, as well as for tailoring behavioural interventions. There is no direct model available internationally that uses such a systems based approach
