Unsignalized cooperative optimization control method based on vehicle speed guidance and information interaction

This paper introduces a new approach for optimization controlling the traffic at an unsignalized cooperative intersection under the Cooperative Vehicle Infrastructure System (CVIS) environment. An unsignalized cooperative optimization control method is proposed for effective intersection operations and management based on vehicle speed guidance and information interaction. For the features of information interaction in CVIS, the proposed method that does not require a traffic signal controller at the intersection; instead vehicle speed guidance and “right of way” information optimized by the method will be show on the DMI of On-Board Unit (OBU). Paper developed an unsignalized cooperative optimization control simulation platform based on the Q-Paramics. Experimental results show that compared with traditional actuated control method, the proposed method can effectively reduce the intersection average delay, number of stops and length of queue.
