Instantaneous Information Propagation in a Traffic Stream through Inter-Vehicle Communication
The advancement of wireless communication technology has made possible the consideration of inter-vehicle communication as a foundation for developing decentralized advanced transportation information systems that would function as a sort of “internet on the road”. In this paper, we discuss the reliability of inter-vehicle communication in a traffic stream, dependent on the distribution of equi...
متن کاملCharacterizing Information Propagation Through Inter-Vehicle Communication on a Simple Network of Two Parallel Roads
In this report, we study information propagation via inter-vehicle communication along two parallel roads. By identifying an inherent Bernoulli process, we are able to derive the mean and variance of propagation distance. A road separation distance of times the transmission range distinguishes two cases for approximating the success probability in the Bernoulli process. In addition, our results...
متن کاملThe Process of Information Propagation in a Traffic Stream with a General Vehicle Headway: a Revisit
Effective intervehicle communication is fundamental to a decentralized traffic information system based on mobile ad hoc vehicle networks. Here we model the information propagation process through inter-vehicle communication when the vehicle headway follows a general distribution. Equations for the expected value and variance of propagation distance are derived. In addition, we provide simple e...
متن کاملInstantaneous Connectivity of One-dimensional Inter-vehicle Communication Networks for General Traffic Conditions
Rapid developments in various frontiers of telecommunications and information technologies could enable the development of next-generation Intelligent Transportation Systems (ITS) that rely on inter-vehicle communications (IVC) to disseminate time-critical and location-based traffic information. In this study, we present a new model for computing the instantaneous multihop connectivity and end ...
متن کاملA Method for Sharing Traffic Jam Information using Inter-Vehicle Communication (Invited Paper)
In this paper, we propose a method for cars to autonomously and cooperatively collect traffic jam statistics to estimate arrival time to destination for each car using intervehicle communication. In the method, the target geographical region is divided into areas, and each car measures time to pass through each area. Traffic information is collected by exchanging information between cars using ...
