Visual Analytics of Traffic Congestion propagation path with Large Scale Camera Data

Chinese Journal of Electronics 2018年第5期27卷 934-941页

作者： SHAN Zhenyu PAN Zhigeng LI Fengwei XU Huihui LI Jiming Hangzhou Normal University Zhejiang Police College

Congestion analysis is essential to traffic control, especially in crowded urban road network. The recent traffic forecasting methods can provide travelers and traffic managers with early congestion warning, yet unable to reveal the relationship of congestion roads. This paper presented a congestion propagation path estimation method based on greedy algorithm to quickly extract these congestion relationships for visual analytics. The data from traffic cameras are applied to build the propagation network based on a directed weighted graph. It describes the process of congestion spreading among different *** to this network, congestion propagation path predicts the process of congestion spreading between different segments. In our visual design, it is applied to demonstrate the segments that will be influenced by the congested road. This is helpful for traffic managers to make effective and efficient decisions. The experimental result shows that our method achieves high accuracy thus prove the effective for the congestion propagation method.

propagation path OF LOW-FREQUENCY SKY-WAVE SIGNALS

Science China Mathematics 1988年第8期 987-995页

作者：潘■德 Lintong Shaanxi Observatory Academia Sinica

The propagation path of the sky-wave signals are studied in detail and some problems and errors occurring in the relevant work in the past are analysed. In the consideration of the refraction effect of the atmosphere, the radio apparent range, the length of the propagation path of the low-frequency sky-wave, the launching angle and the incidence angle with their influence on the time delay and the field strength of the LF sky-wave signals are deduced and calculated. The predictions on the D-layer of ionosphere and the time delay and field strength of the LF sky-wave signals are studied and the results show that the difference between the predicted values and the measured values are within ±1.5μs and ±2.5 dB for the time delay and the field strength respectively and that the accuracy of the timing via LF sky-wave can be raised to ±1.2μs and ±2.8 μs st daytime and at night respectively.

In recent years,some propagation paths in the socialist core values have adopted invalid means to carry out the network propagation activities,which have seriously disrupted the normal social ***,the research methods of the traditional propagation path mainly rely on manual analysis,which has poor efficiency and is not suitable for the study of the mass propagation *** at solving the aforementioned problems,an valid propagation path of the socialist core values that takes the structural equation into consideration is put forward in this paper,in which the propagation path is analyzed from three aspects as the following:the state of the propagation path,the historical socialist core values and the neighbors of the propagation *** addition,structural equation is used to carry out the automatic path selection on the normal propagation paths and other propagation *** experimental results show that the method put forward in this paper can be used to carry out valid study on the valid path that can strengthen the propagation of the socialist core values,and the accuracy rate is as high as 95%.
