Workshop Description:
Analysis, Modeling, and Simulation tools are an important component in determining the impact of the cooperative automated vehicle deployment. The deployment of cooperative automated vehicles (CAVs) will create opportunities and challenges for transportation system researchers and users that require transformative changes in simulation modeling algorithms, calibration and validation methods. These CAVs will create many uncertainties or concerns that simulation needs to model. How will these CAVs interact will other vehicles (human-driven vehicles) and moving objects such as pedestrians, bicycles, etc? How will the measurement errors from the numerous sensors (e.g., radar, lidar, GPS, etc.) affect the performance of these vehicles in both safety and mobility? What effect will the false positives and false negatives of object detection and position have on these CAVs? How will the dynamic temporal and special changes of the infrastructure affect the efficiency and effectiveness of these CAVs? How can we enable Analysis, Modeling and Simulation Tools to evaluate CAV applications and the uncertainties that will exist. To answer these questions, the Analysis, Modeling, and Simulation tools will need to be updated to reflect a traffic stream with mixed levels of emerging technologies—such as connectivity and automation—that affect both microscopic and macroscopic traffic characteristics. In addition, the various levels of uncertainties will need to be modeled to understand their impact on the safety and mobility performance.

7- Workshop Format
The workshop will start by a set of presentations related to the latest data collection platforms available to collect data on connected and automated vehicles. These data collection platforms will be either associated with real-world deployments or virtual/simulator environments. The panel of speakers will then be asked several questions by the audience. Afterwards, the audience will participate further in the discussion to identify several key research themes/thrusts. The objective is to outline/summarize the presentations while identifying possible areas of collaboration between the sponsoring/cosponsoring committees from one side and the vehicle instrumentation and driving simulator companies and the public agencies from the other side to further improve the discussed connected and automated vehicle technologies in order to be utilized for traffic flow modeling, calibration and validation. The synthesis of the workshop will serve as a guideline on the accuracy of existing real-world deployments and virtual simulation environments in representing the future of our roadways in a connected and automated transportation system.
8- Workshop Description
Connected and automated vehicles are continuing to be the subject of interest of policy makers, transportation agencies and the industry. Several efforts by major public (i.e. federal and local transportation departments) and private (industry companies) agencies have been made to collect data associated with these type of vehicles in order to understand their impact on the performance of our transportation system. These efforts may be associated with constructing connected and automated systems test-beds (involving 2 equipped vehicles and infrastructure components) or recreating these systems in simulator/virtual environments. However, such efforts are not completely shared yet with traffic researchers and practitioners and the corresponding findings are still not clear. This workshop aims at presenting 1) the latest virtual/simulator environment implementations efforts and 2) the real-world deployments/instrumentations efforts made to model, calibrate and validate traffic flow dynamics with the presence of connected and automated vehicles. The challenges faced in these efforts, the limitations of the associated tools/test-beds, and the opportunities to be still explored will be identified for possible future public/private/academic collaborations and initiatives.
