Project Details

Project Abstract: 

The goal of this analytical project is to develop and evaluate research methods to assess drivers’ acceptance and behavior when using Cooperative Adaptive Cruise Control (CACC) based upon specific scenarios derived from the mobility service concept outlined here. Human factors testing in field experiments and driving simulators will likely be needed, but the research requirements and the approaches to address them are not yet known and should initially be defined in this project.


The objectives of this exploratory project are to:

(1) Define a small set of scenarios, based upon the base Cooperative Adaptive Cruise Control (CACC) concept of operations, that recognize differences in the way this concept can be realized. These scenarios will, in turn, identify a series of independent variables that, when compared to current conditions, provide a basis for describing driver behavior and other human factors issues associated with the concepts.

(2) Identify possible key drivers and other human factors issues that must be addressed in order to develop effective mobility services as outlined here.

(3) Frame the issues by creating specific research questions or hypotheses.

(4) Identify and describe, in detail, possible methods of answering these research questions.

(5) Outline specific requirements for human factors testing methods and equipment.

(6) Establish general requirements and estimate costs of additional resources needed at Turner-Fairbank Highway Research Center to conduct these tests.

(7) Identify other appropriate resources, including driving simulators and test tracks, that might be employed to conduct these studies, either initially or as a followup step.
