This paper presents a visual attention based convolutional neural network (CNN) to solve the image classification problem in the real complex world scene. The presented method can simulate the process of recognizing objects and find the area of interest which is related with the task. Compared with the CNN method in image classification, the model is proficient in fine-grained classification problem...
This paper proposes a new algorithm that employs Adaptive Dynamic Programming(ADP) to solve the distributed control problem of urban traffic with an infinite horizon. Urban traffic congestions lead to a lot of time consumption and exhaust emissions. So alleviating congested situation will have a good impact on both economy and environment. The signal control at urban intersections is an effective...
This paper presents a reinforcement learning (RL) algorithm for multi-agent patrol tasks, which can be thought of as a dynamic programming problem with stochastic demands. We define the cover rate as the reward, the multi-agent physical positions including edges and nodes as the state, and the nodes adjacent to the agent as the action to model the patrol task. The modeling of this problem is totally...
Urban traffic congestions lead to a great deal of time consumption and exhaust emissions. So alleviating congested situation will have a good impact on both economy and environment. The signal control at isolated intersections is an effective and most important way to reduce the traffic jams and collisions. A lot of control theories including traditional mathematical ways and modern intelligent ways...
Ramp metering has been developed as a traffic management strategy to alleviate congestion on freeways. Most ramp metering control algorithms are concerned without queuing consideration, because its still a tough job to deal with the problems of coordinated multiple ramps metering with queuing consideration. In this paper, on the basis of our previous studies, we use action-dependent heuristic dynamic...
This paper proposes a fuzzy logic signal controller with adaptive dynamic programming optimizing for traffic intersection. Because fuzzy logic has a clear advantage that it is able to use expert knowledge well, we adopt it in our controller. As adaptive dynamic programming is an advanced technology which is suitable for solving non-linear stochastic system optimizing problems, we use it to optimize...
This paper aims at developing near optimal traffic signal control for multi-intersection in city. Fuzzy control is widely used in traffic signal control. For improving fuzzy controlpsilas adaptability in fluctuate states, a controller combined with neuro-fuzzy system and adaptive dynamic programming (ADP) is designed. This controller can be used for cooperative control of multi-intersection. The adaptive...
Increasing dependence on car-based travel has led to the daily occurrence of freeway congestions around the world. In order to improve the worse and worse traffic congestion situation and solve the problems brought with it, a new kind of effective, fast, and robust method should be presented. Ramp metering has been developed as a traffic management strategy to alleviate congestion on freeways. But,...
