In the method of driving simulation, behavioral characteristics of driver can be learned safely even under abnormal state. This kind of experimental method also contributes to analyze driver's emergency response in a variety of complex conditions and it has a good experimental reproducibility, which can be applied in traffic safety, accident reconstruction, ergonomics and other fields. The combination...
The recurrence of traffic, environment and traffic accident scenery on the road is significant to research traffic flow, road and traffic safety, which could provide "humanization" of road safety traffic system with safe, economic, repeatable and ideal experiment platform. Drivers are direct users and key factors in the safe road traffic-system. Road traffic human-computer interface simulator...
Evaluating of Variable Speed Limits (VSL) is often only possible in indirect ways due to the lack of sufficient data. Since the majority of safety benefits is expected from warning and increased alertness of drivers, evaluation methods that focus on the informative nature of VSL such as the detection rate (DR) and false alarm rate (FAR) are useful tools. In the state-of-the-art these are typically...
Road accident hotspots Identification is important in road safety improvement project, especially in aspect of effective funds allotment. This paper presents a simple methodology called dynamic step filtration method to study the spatial patterns of accidents in a highway or a highway network. The dynamic step filtration analysis is improved from average and steady step filtration method, basing on...
Rollover accidents are of special concern for vehicle safety. Rollover accidents are especially violent and cause greater damage and injury than other accidents. In order to prevent rollover, it is necessary to know when a rollover is imminent. Thus, a approach based on energy considerations is introduced. Then, a linear bicycle model is used as a reference model, and it provide the reference values...
This study investigated what emotional feedback was effective for helping elderly drivers understand and modify their driving problems in the hypothesized driving re-education program using a driving simulator. A victimizer experience and the data review from the victim's perspective were compared with the image review from the objective, bird's-eye angle. The effect of combination of the victimizer...
Transition signal is one of the main factors contributing to the safety of intersection, scientific transition signal setting can greatly improve the traffic safety and efficiency. By analyzing the present situation of transition signal setting in our country, It is pointed that there is something ambiguously defined and non operating, and even some logical error in the law of road traffic safety...
A single-vehicle crash is a typical pattern of traffic accidents and tends to cause heavy loss. The purpose of this study is to identify the factors significantly influencing single-vehicle crash injury severity, using a data selected from Beijing city for a 4-year period. Rough set theory was applied to complete the injury severity analysis, and followed by applying cross-validation method to estimate...
This paper applies the principle of vehicle dynamics and traffic conflict theory to analyze the driver behaviors and speed of next two vehicles with green lights. Based on the analysis, we propose the smallest calculation formula of green change interval which ensure vehicles cross intersection safely. Combining with traffic psychology, we study the impact of signal countdown device to green change...
Driving safety support is one of the most attractive applications of an intervehicle communications system. Real-time and reliable packet exchange among vehicles is key to offering timely warnings to drivers in order to avoid fatal accidents. In this article we introduce multicarrier multicode spread Aloha (MM-SA) system, an intervehicle communications system developed to satisfy challenging requirements...
In order to evaluate road safety in design stage, virtual simulation tests are proposed. The system includes the modeling of virtual road based on Creator, the development of vehicle dynamics model and 3D model, the development of real-time simulation software based on Vega and road safety evaluation model. Through the visual simulation tests, the vehicle speed inducement effect of the road can be...
Traffic system is a dynamic complicated one which is constituted of some factors. Traffic accident will happen if these factors mismatch with each other. Safety level of traffic accident scene affects occurrence rate of secondary accident. In order to evaluate safety level of traffic accident scene, prevent from secondary accident happening and protect the policemen, crowds by the scene and party...
About 87 percent of road traffic accidents in China resulted from the incident errors of automobile drivers. Many practical analyses showed that the unreasonable installation of road traffic facilities will influence the drivers with un-efficient or even wrong guidance which would induce accidents. The dynamic visual characteristics of drivers are most closely related to traffic accidents. The video...
Vehicle safety is based on the avoidance of accidents (active safety) and reduction of injuries in case a crash isnpsilat preventable (passive safety). Therefore, the motion of the vehicle is measured with suitable sensors. The data analysis takes place in qualified vehicle control units. A vehicle stabilisation is calculated in the electronical-stability control unit (ESC). The restraint systems...
