In Fig. 4, the communication graph from the Abilene network is presented, which consists of 11 nodes and 14 edges. Each node represents the physical backbone router and the node features include the inflow and outflow traffic volumes. Each edge represents the physical transmission link and the ...
Traffic flow is considered as a critical feature of intelligent transportation systems (ITS). Accurately forecasting future vehicular volumes is an effective means of mitigating traffic congestion. However, the nonlinear and complex traffic flow characteristics make the traditional approaches unable to achiev...
Existing methods have created a solid foundation for characterizing congestion propagation; however, they are either built upon simplified assumptions in traffic flow theory or predefined relationships among road sections, which would lead to downgraded accuracy in practice. This paper proposes a dynamic ...
Urbanization is beneficial to the cities’development,butit has also brought many problems, such astraffic congestion交通拥塞,environmental pollution, social injustice and so on.Given this,we should abide by the objective law of urbanization,propelling推动the sound development of the whole society. ...
To improve the prediction accuracy of traffic flow under the influence of nearby time traffic flow disturbance, a dynamic spatiotemporal graph attention network traffic flow prediction model based on the attention mechanism was proposed. Considering the macroscopic periodic characteristics of traffic flow,...

To formalize this idea further, we assign a congestion related latency function le(x), x≥ 0, to each e∈ E. We assume that le(x) is a nonnegative, nondecreasing, and continuous function of its parameter. Then, for an induced network flow f, the latency experienced by data traffic ...
Expanding cities face many transportation-related problems, including air pollution and traffic congestion. Early intervention based on traffic forecasting is seen as the key to improving the efficiency of a transportation system and to alleviate transportation-related problems. In the development and ...
