Rated model of driving-related processes and objects The Salience, Effort, Effort and Value (SEEV) model for predicting the distribution of visual attention contains a parameter called 'value' which represents the importance of a certain area of the field of view concerning a given task context.

Does anyone know a project or study that actually did a 'value model' for the traffic context?
A 2006 study by Horrey, Wickens and Consalus implemented a computational SEEV (Salience, Effort, Effort, Value) model for driving behavior that predicted scanning behavior, which I surmise is what was meant. The authors conclude:


  The most important practical implication of the current results is
  that a simple expected value version of the SEEV model provides
  a plausible and effective predictive model of scanning in driving.


This seems to fit your request.
