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.
- 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.
The project is devided in workplans consisting of a Methodological Phase (months 0-6), an Experimental Phase (months 9-24) and a Validation Phase (months 25-34). Seven WorkPackages have been developed. The function of each is distinct, but provides outputs relevant to other WPs.
- 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 cognitve 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 deynamic performance.
- there are severe problems for elderly drivers using IVIS while driving.
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
