Dynamic vehicle detection and tracking can provide essential data to solve the problem of road planning and traffic management. A method for real-time vehicle detection and tracking using deep neural networks is proposed in this paper and a complete network architecture is presented. Using our model, you can obtain vehicle candidates, vehicle probabilities, and their coordinates in real-time. The...
Aimed at the problem that it is easy for buses to roll in the extreme-turn conditions, the paper finished a series of analysis. First, bus turning driving dynamics model was established based on the effect of suspension motion on roll angle. In the extreme-turn conditions Roll stability and critical roll angle threshold were analyzed, and formulas of roll angle prediction and roll angle threshold...
Based on the force analysis of the roll for vehicles under the extreme turning, comparative analysis and simulation verification are carried out for the two kinds of calculation methods of the roll critical safety speed under the situations of whether or not taking account of the effect of suspension in the vehicle roll analysis. From three aspects of "driver operation — vehicle structure parameter...
Vehicular networks have been increasingly used for applications like road infrastructure monitoring and traffic jam detection, etc. Data forwarding is a well-known challenging problem in vehicular networks, which suffers from delay and error due to the frequent network disruption and fast topological change. The minimizations of the delivery delay and network cost are both central to data forwarding...
Vehicular ad hoc network(VANET) is increasingly studied recently due to its promising benefits to the urban life. The roadside unit(RSU) is one of the most important components for VANET. An effective deployment of RSUs will enhance the efficiency of the data delivery in VANET. In this paper, we propose to address the RSU deployment problem by formulating it as a mobility clustering problem. We adopt...
The proliferation of location-based services and applications calls for provisioning of location service as a first class system component that can return accurate location fix in short response time and is energy efficient. In this paper, we present the design, implementation and evaluation of WheelLoc — a continuous system location service for outdoor scenarios. Unlike previous localization efforts...
