The aim of HASTE (Human Machine Interface And the Safety of Traffic in Europe) is to develop methodologies and guidelines for the assessment of In-Vehicle Information Systems (IVIS). To date, there have been attempts to provide manufacturers and testing authorities with a set of guidelines to assess the likely impacts of IVIS on the driving task, usually in the form of a checklist. Such checklists provide a tool that enables the identification of likely problems but they do not attempt to quantify safety problems.
Objectives include:
- to identify traffic scenarios in which safety problems with an IVIS are more likely to occur,
- to explore the relationships between task load and risk in the context of those scenarios,
- to understand the mechanisms through which elevated risk may occur in terms of distraction and reduced Situation Awareness,
- to identify the best indicators of risk (accident surrogates),
- to apply the methods devised to evaluating real systems,
- go recommend a pre-deployment test regime that is both cost effective and possesses the validity to predict performance,
- to recommend an approach for the preliminary hazard analysis of the HMI of an IVIS concept or design, including issues related to reliability, security and tamper proofing,
- to supply a validated methodology for preliminary hazard analysis of IVIS HMI supported by case studies.
Key results:
It is possible to devise an efficient and effective test regime for assessing the safety of interaction with an in-vehicle information system (IVIS) while driving.
The major constituents of a recommended test regime have been defined.
Visual distraction and cognitive distraction from the use of IVIS have very different impacts on the primary task of driving.
Static performance on an IVIS does not reliably predict dynamic performance.
There are severe problems for elderly drivers using IVIS while driving.
Technical implications of results:
There are still some substantive issues to be examined in order to fully specify a test regime:
coring and weighting issues,
test re-test reliability,
applying the HASTE protocol to the older driver.
