Traffic Level of Service Generation from Video Detection System Using Cluster Analysis
نویسنده
چکیده
In general, traffic service quality can be described by different parameters and the traffic level of service (LOS) is mainly determined by one of them, such as traffic flow or traffic speed. However, the traffic phenomenon is extremely complex; its characteristics cannot be well represented only by one single parameter. The aim of this research is to determine a more representable LOS based on three measured parameters, derived from the local traffic video data collected in Hefei, China. The result of this work will be used for data fusion with floating car data (FCD) and other traffic information in order to more accurately capture the current traffic situation of the city.

Traffic Scene Analysis using Hierarchical Sparse Topical Coding
Analyzing motion patterns in traffic videos can be exploited directly to generate high-level descriptions of the video contents. Such descriptions may further be employed in different traffic applications such as traffic phase detection and abnormal event detection. One of the most recent and successful unsupervised methods for complex traffic scene analysis is based on topic models. In this pa...

متن کاملMethod of Video-Measurements of Traffic Flow Characteristics at a Road Junction
In the theory of traffic flows the main characteristics are: intensity, speed, and density. They make it possible to use hydrodynamic models. In connection with the development of modern highways and road networks, traffic flows behavior is becoming more and more complex and diverse. In particular, the B.Kerner studies have shown that the laminar solution of hydrodynamic models is poorly corre...
