Abstract:This report presents a high-level test and evaluation framework for cooperative driving automation systems that have the potential to significantly improve mobility and enhance traffic flow stability with better safety. It focuses on the test and evaluation of vehicle platooning that uses cooperative adaptive cruise control (CACC) and vehicle-to-vehicle communications to enable the automatic synchronization of longitudinal movements of a string of vehicles. This report defines comprehensive test procedures to facilitate the deployment of vehicle platooning concepts along an evolutionary path of enhanced system functions and capabilities, which consist of a progressive series of testing from very basic testing under closed track and normal driving conditions to more complex test scenarios and driving conditions on a test track and public roads. Results from first-pass, test-the-test procedures are summarized for a 5-car platooning proof-of-concept that was tested in July 2016 at a test track. This report delineates performance measures for car platooning and explains the test data analysis. Based on test results, this report offers several recommendations for features of the CACC-based vehicle platooning system that should be further assessed and potentially improved upon in the next iteration of the application.
