The cooperation between connected and automated vehicles (CAVs) has emerged as a promising way to improve traffic efficiency safety for ramp merging on highways. Existing research mostly focused the collaboration of individual CAVs, while cooperative strategy in mixed considering vehicle platoons been less explored. To address above problem, this study aims build connections sequence scheduling motion planning traffic, where CAVs platoons, coexist. First, optimal control strategies are...

Next location prediction plays an essential role in location-based applications. Many works have been employed to predict the next of object (e.g. a vehicle), given its historical records. However, existing methods not fully addressed importance contextual features, such as short-term traffic flows. In this paper, we propose deep learning-based model incorporate features into prediction. First, conduct similarity mining among candidate locations. Second, trajectories, including both...

Connected and Autonomous Vehicle (CAV) has attracted much attention as it provides promising solutions to improve traffic performance in many scenarios, especially unsignalized intersections. However, for intersections where both CAV Human-driven (HDV) exist, reduce the impact of HDV uncertain behaviors, existing related research tend simplify scenario or behavior characteristics at intersections, ensuring passing safety without collaborative decision-making on efficiency optimizations. To...

The laid theoretical foundation for position control processing track planning Robot.

The on-ramp merging in multi-lane highway scenarios presents challenges due to the complexity of coordinating vehicles' and lane-changing behaviors, while ensuring safety optimizing traffic flow. However, there are few studies that have addressed problem ramp vehicles cooperative lane-change mainline within a unified framework proposed corresponding optimization strategies. To tackle this issue, study adopts cyber-physical integration perspective proposes graph-based solution approach....

As automotive companies standardize their electronic control units (ECUs) on a common electrical architecture across all vehicle platforms, more and software-enabled features will be delivered using assembly plant flash programming. Assembly programming is the process by which software or calibration data sets are downloaded to an off-board tool during final process, thus postponing product differentiation customization, reducing rate of growth in number unique ECU part numbers,...
