According to many studies, motor vehicle collisions lead deaths and disabilities, bring about huge economic losses societies individuals around the world. If risky scenarios could be recognized driver timely warned, frequency of traffic accidents reduced effectively, safety improved. This article summarizes current state research on warnings under connected environments-from risk recognition algorithms, collision avoidance systems, dangerous event identification notification methods,...
With the development of sensor and network technologies, a type hybrid (HSN) has been developed in traffic information acquisition systems. Sensor types HSNs are diversified, mostly by batteries or solar energy as their source. Energy determines lifetime. If consumption sensors can be reduced from aspect communication, saved lifetime increased, so to improve benefit efficiency whole network. To optimize HSNs, graph theory-based model was proposed considering nodes’ connectivity power data...
Aiming at efficiently mapping multiple virtual optical networks (VONs) on a shared substrate network. This paper proposes load balancing algorithm that is based key-link and resources contribution degree (RCD) for VONs (KLRVM) in elastic (EONs). In this algorithm, nodes gets the network status according to proposed RCD, comprehensively considers computing resource, shortest path length available bandwidth. While link length, occupied bandwidth parameters are holistically considered complete...
For efficiently solving the problem of special resource allocation in network function virtualization (NFV) scenarios with virtualized functions (VNFs) precedence constraints, we formulate such a as an integer linear programming (ILP) model and propose novel mechanism to both build map service chain (SFC) coordinated method inter-datacenter networks over elastic optical infrastructure. We design VNFs reusing deploying that is based on bandwidth change ratio each request. In chaining mapping...
In this paper, we discuss the impacts of fog warning systems on driving behavior and traffic safety under different conditions. Firstly, in order to obtain data, an empirical simulator platform was established based a real-world road Beijing. The comparison study conducted for eight scenarios which comprise four Thirty-five test drivers drove instrumented vehicle times, 2 conditions (light fog, heavy fog) × 4 (No warning, Dynamic Message Sign only, On-Board Unit & Sign). results show that...
Driving confidence psychology can guide drivers in calm driving operation when dealing with traffic issues, which is of substantial significance for reducing the accident rate and improving road efficiency. This study mainly analyzes differences face an emergency braking event a front vehicle warning as opposed to same situation without information. First, connected environment was designed based on simulation technology, provide information from emergency-braking by using onboard...
