In this paper, we present computer simulation results of traffic flow on a two-lane roadway with different types of vehicles, cars and trucks for example. We consider two classes of two-lane traffic cellular automaton models, namely the well known Nagel-Schreckenberg model and an extension of the Fukui-Ishibashi model. These two models, which differ in their acceleration limits, show an importa...

This paper uses a semi-parametric Poisson-gamma model to estimate the relationships between crash counts and various roadway characteristics, including curvature, traffic levels, speed limit and surface width. A Bayesian nonparametric estimation procedure is employed for the model’s link function, substantially reducing the risk of a mis-specified model. It is shown via simulation that little i...

Cooperative vehicle-highway systems offer the potential to enhance the effectiveness of active vehicle safety systems which have entered the marketplace for light vehicles and heavy commercial vehicles. Cooperative intelligent vehicle-highway systems (CIVHS) offer an improved level of overall functionality. These systems are cooperative in that the vehicles can receive information from the road...

Road safety is a very important issue in many jurisdictions. Road collisions, which have been identified as a major public health problem by the World Health Organization, are the 11th leading cause of global deaths.1 This problem is being addressed in North America through improved education, enforcement and engineering. Having access to better information systems and tools to support decision...

An advanced break or a vast region of pressurisation may occur when the working face passes through an abandoned roadway, resulting in roof falling water inrush. The stress evolution passing roadway coal mine was comprehensively discussed using theoretical analysis, numerical simulation, and field monitoring. In this study, calculated critical width where main bound to 5.4 m. Reducing suspended...

Effective control of deformation failure surrounding rock in deep roadway has become an important prerequisite for the safe and efficient development coal resources. In this study, field measurement study area’s in-situ stress was carried out specific engineering geological conditions KCM −967 m level west-wing main track roadway. The roadway’s full-section features were summarized analyzed, no...

To study the deformation and failure mechanisms of soft rock mining roadways, 1506 return airway Anyang Coal Mine is taken as engineering background. Based on limit analysis theory, a model based rigid slider system constructed to assess surrounding roadway. The formulas for calculating self-weight power in velocity discontinuity line roadway, work pressure, energy dissipation rate are derived,...

In advanced driver assistance systems and autonomous driving vehicles, many computer vision applications rely on knowing the location of the vanishing point on a horizon. The horizontal vanishing point’s location provides important information about driving environments, such as the instantaneous driving direction of roadway, sampling regions of the drivable regions’ image features, and the sea...

The coal information system based on the electric power line was put forward after analyzing briefly the structure of mine distribution power network in roadway underground, connected with communication and monitoring networks existed already. The system uses a multi-level distributed bus network structure, roadway where harsh conditions, using a combination of multi-carrier and spread spectrum...
