Development and Evaluation of Selected Mobility Applications for Vehicle-Infrastructure Integration

The objectives of this project are to design, test, and evaluate three ways of employing wireless communication, specifically to:  (1) Use probe vehicle data to characterize local freeway traffic speed and density, and then use that information to generate reference speed advisories back to individual drivers and vehicles to enact the speed control, to dissipate shock waves, and to improve throughput.  (2) Use vehicle-to-vehicle communication to generate reference speed and gap adjustment commands to cooperative adaptive cruise control systems, to enable them to follow more closely and safely, and also dissipate shock waves and increase throughput.  (3) Use vehicle-to-vehicle communication between heavy trucks to enable them to operate in close-formation automated platoons, increasing lane capacity, and reducing aerodynamic drag.  The fundamental technical approach follows the general iterative system paradigm of model-design-test-model. Mathematical and computer models will be used to predict system performance and interactions with the operating environment. These models will be the basis for making design trade-offs and focusing on the preferred designs for testing. The preferred designs will be developed in prototype hardware and software (building on extensive legacy hardware and software from previous projects), and then tested under the most realistic conditions that are possible within schedule and budget constraints. The results of the tests will then be used to update the models, and the models will be used to predict the impacts of widespread implementation. Additional milestones have been defined for the intermediate completion of stages of system design, for the completion of test vehicle hardware and software installations, and for demonstrations that will be offered to the sponsors and stakeholders.
