The focus of this survey is on spatio-temporal data mining and database retrieval for visual traffic surveillance systems. In many traffic surveillance applications, such as incident detection, abnormal events detection, vehicle speed estimation, and traffic volume estimation, the data used for reasoning is really in the form of spatio-temporal data (e.g. vehicle trajectories). How to effective...

Traffic matrix reflects the volume of traffic that flows between all pairs of sources and destinations in a network. Its element is referred to as an Origin-Destination (OD) pair (or flow). And traffic matrix gives network operators a global aspect of how all the traffic in a large-scale network flows. Thus, with traffic matrix as a key input of traffic engineering and network management, it is...

the purpose of this study is to identify the effect of ordinary kriging (ok) and inverse distance weighted (idw) estimation methods for the delineation of mineralized zones based on subsurface data using concentration–volume (c–v) multifractal modeling in the dardevey iron ore deposit, ne iran. variograms and anisotropic ellipsoid were generated for the fe distribution by the above estimation m...

In this paper, a vision-based real-time traffic analysis system is presented, which can analyze vehicles in traffic from a traffic video sequence. This paper discusses object detection, and tracking of objects in multiple video frames. The functionalities of traffic analysis using computer vision include vehicle speed estimation, traffic flow direction estimation, traffic density estimation and...

conclusions it is proposed that the needed research be conducted at national and regional levels in coordination and cooperation with international organizations active in the field of traffic crashes in various parts of the world, especially in asian, african and latin american developing countries, where a greater proportion of pedestrian traffic crashes occur. results a review of the studies...

Fatigue driving is a main cause for road traffic accidents. In case an alarm can be sent to drivers one second before the potential traffic accidents, 90% similar traffic accidents can be avoided. Facial expression recognition of drivers is an important component of fatigue driving prewarning system. For the continuous video images obtained, facial features of eyes, nostril and mouth are firstl...

Researches using existing statistics and data collected from the area of study help officials at decision-making, to improve the region's problems, like the problem of the high rate of accidents in the region, despite the low volume of daily service. The uses of roundabouts in many parts of the world have many advantages over intersections, amongst them are increased safety and capacity and red...
