This research project aims to increase knowledge about the preferences of stakeholders involved in the implementation of Advanced Driver Assistance Systems (ADAS). Therefore, first stakeholder preference models will be developed and estimated. Next, using these models, the roles of stakeholders in the implementation process will be analyzed. Finally, preferences and roles will be used to develop a decision tool for development of ADAS implementation strategies.

Keywords: stakeholders, Advanced Driver Assistance Systems (ADAS), modelling

Background and problem definition

Policymakers are considering ADAS as a serious measure for reaching their transport goals. ADAS that are currently available on the market, such as navigation support and Adaptive Cruise Control, contribute to traffic safety and efficiency only modestly.  Better effects are expected of more technologically advanced integrated and co-operative ADAS, but for several reasons implementation is slow. One of the factors delaying implementation is the knowledge policymakers have about stakeholder preferences, which is necessary to guarantee the success of future ADAS policy development.

Methodological approach

In this research project a conceptual model of stakeholder preferences will be developed for each stakeholder, based on the stakeholder’s outcomes of interest. These models will be estimated by surveying the stakeholders on their preferences and stated preference modelling techniques. The estimated models will be combined with knowledge on stakeholder roles, derived from a gaming exercise, this knowledge on stakeholder preferences will be used to develop an appropriate decision tool.

Scientific and societal relevance

The results of this research will support policy- and decision making on the implementation of ADAS. Current research on stakeholder preferences regarding ADAS show serious shortcomings. Rarely the distinction between different stakeholders is considered. Next the main focus is on identifying preferences for system characteristics instead of how stakeholders value a system’s outcomes of interest, which is a necessity from a policymaking point of view. Finally, the way stakeholder preferences for new systems might evolve, has not been considered.

Expected practical and scientific results

Expected practical results are mathematical models that can be used to explore stakeholder preferences regarding ADAS implementation, and a decision support tool based on these stakeholder preferences. Expected scientific results are theoretical knowledge on how to model stakeholder preferences and empirical knowledge about stakeholder preferences, its differences and its variation in time.
