Vehicular ad-hoc network (VANET) is an important component of intelligent transportation systems, in which vehicles are equipped with on-board computing and communication devices which enable vehicle-to-vehicle communication. Consequently, with regard to larger communication due to the greater number of vehicles, stability of connectivity would be a challenging problem. Clustering technique as ...

The Intelligent Speed Adaptation in vehicles using GPS technology is a method of speed adaptation in vehicles based on its position on the highway. The position can be recognized using the GPS receiver. The main objective is to make the system simple. The Toll gates on the highway are equipped with a transmitter that transmits a very small data to the receiver system in the vehicle. The receive...

Packet loss in block erasure channels creates a randomly switching networked system that impacts control performance significantly. This paper employs safety of highway vehicle platoons as a platform to study such an impact. By autonomous inter-vehicle coordination, a platoon can potentially enhance safety, improve highway utility, increase fuel economy, and reduce emission. By comparing differ...

Control systems have always been a vital part of the novel technological advancements of human being in any industry, especially transportation. With the introduction of the idea of autonomous driving, classical control systems are not effective anymore and the need for intelligent control systems is inevitable. Advanced Driver Assistance Systems (ADASs), which are systems proposed to help driv...

Advanced Driver Assistance Systems (ADAS) are in the focus of the vehicle control research. In the paper, the design method of a controller for a longitudinal ADAS system of a test vehicle is proposed. The cruise control must guarantee precise velocity tracking at varying vehicle mass and road inclinations. The mass variation and road slope changes are formulated as disturbances of the system. ...

With the rapid vehicle volume growth on roads, the performance of urban road traffic systems is a major concern to transportation planners, road users, and all members of the urban community. The evaluation of the performance measures relies on the accuracy and reliability of the collected traffic data. This paper describes a method of extracting transportation information using global position...

The existing intelligent vehicle trajectory-planning methods have limitations in terms of efficiency and safety. To overcome these limitations, this paper proposes an automatic driving method based on a variable Gaussian safety field. Firstly, the time series bird’s-eye view is used as input state quantity network, which improves effectiveness trajectory planning policy network extracting featu...
