A high accident potential exists at high-speed signalized intersections where an area close to an intersection, called a dilemma zone (also known as decision zone). The potentially negative impact of dilemma zones on the operational capacity and safety of signalized intersections, has motivated a great deal of effort to the mitigation of the dilemma zone issue. This mitigation system have been pursued...
This paper presents a decentralized merging assistant for mixed traffic situations aiming to increase traffic flow stability around the merging area by minimizing the conflict and limiting the changes in speed. The algorithm encourages early and smooth deceleration of the mainline vehicles upstream of the merging area in order to create gap for ramp vehicle. Simulation results show that the effectiveness...
In this paper we propose a novel design for the Lane Change Assistant (LCA). For drivers on the highway, LCA advises them on whether it is safe to change lanes under the current traffic conditions. We focus on how the LCA can provide a reliable advice in practice by considering the issues of changing circumstances and measurement uncertainties. Under some generic assumptions we develop a micro-simulation...
Traffic simulation technology is a practical computer simulation technology, and the development of traffic simulation software systems are usually based on the knowledge of computer and traffic. Aiming at the situation of china, an improved approach of the traffic simulation is proposed in this paper. Under the special condition in China, the mixed traffic whose lanes are not divided clearly is chaotic...
Virtual reality combining with vehicle running can exhibit vehicle's status dynamically in a virtual vision environment. The characters of intelligent vehicle running are analyzed. A virtual simulation system about intelligent vehicle running is realized based on virtual reality technology and MultiGen Creator/Vega, VC++, the constructing process of the system is introduced, the safety distance models...
