16. Abstract
CARMASM is an initiative to enable collaboration for research and development of cooperative driving automation (CDA). The goal of CDA is to improve safety, traffic throughput, and energy efficiency of the transportation network by enabling vehicles and the infrastructure to communicate to coordinate movement. This project aims to advance the CARMA ecosystem to enable further capabilities for CDA participants to interact with the road infrastructure, to enhance infrastructure performance, to improve network efficiency, and to reduce traffic congestion through transportation systems management and operations strategies on arterials. This concept of operations has two components: including a critical time step estimation (designed for roadside equipment) and trajectory smoothing for cooperative automated driving system-equipped vehicles (designed for CARMA PlatformSM) with the available vehicles' real-time information. The authors expect this approach to increase throughput and reduce energy consumption while ensuring safety at signalized intersections with a fixed-time/actuated signal setting. |
