About This Document

The objectives of Task 2c (develop and validate equations) were to determine (1) how various vehicle parameters that are measurable by technologies in the SAVE-IT program can be combined to predict drivers’ subjective ratings of driving task demand (especially as a function of road geometry and traffic) and (2) when demand is rated by drivers as being too high to permit safe completion of specific telematics tasks, with task duration being a factor of particular interest.
