Role and Significance of Variable Message Signs in Traffic Management Systems
The article depicts the role of Variable Message Signs in traffic management systems. VMSs play a big role in improving the traffic safety, as they are an important source of information for the driver, thanks to their clarity and legibility. The fulfilment of formal and legal requirements regarding the VMS is an important aspect of their implementation. The article describes the principles of ...
متن کاملTraffic Signs Inventory System
The paper is focused on practical application of Cambridge Correlator. The goal is to propose a traffic signs inventory system by using excellent characteristics of correlator in the rapid optical correlation. The proposal of this inventory system includes obtaining of traffic signs to create the database either collecting the GPS coordinates. It is necessary to know the traffic signs position ...
متن کاملDetecting Related Message Traffic
Governments routinely intercept messages as part of counterterrorism efforts. We consider the problem of identifying and associating messages between members of a threat group when the content is apparently innocuous and senders and/or receivers are not identifiable as particular people. We show that clusters of related messages can be identified when they use words in correlated ways (which al...
متن کاملDetection and Extraction of Road Traffic Signs
The real-time road traffic sign recognition focused on the application of computer vision techniques in automatic detection and classification of video images of traffic signs placed on roadways acquired from moving vehicles. In this work, we present results of an attempt to locating traffic signs placed on local roadways based on image processing techniques. The developed algorithm is based on...
متن کاملDetection and Recognition of Alert Traffic Signs
Traffic signs provide drivers important information for safety and efficient navigation. Automatic detection and recognition of traffic signs inevitably become more popular. In this paper, an efficient algorithm/platform is presented to achieve automatic alert traffic signs detection and recognition. Histogram of Gradient (HOG) is adapted to extract features and an over-complete set of 1680 fea...
