Firstly, the wave-number spectrum method is used to obtain the component of main vibration mode. Then the evanescent wave theory for infinite cylindrical shell is adopted to approximately analyze the decay characteristic of near field evanescent waves from the finite cylindrical shell. Based on the analysis results for evanescent waves, the interface between the near field and far field and the position of artificial boundary of numerical methods can be determined. In the end, comparison of numerical results between the FE-IE method and FE-BE method shows the validation of the approach for analysis the decay characteristic of near field evanescent waves. The proposed method can be used to evaluate the decay characteristic of near field evanescent waves from finite cylindrical shell structures and simple shape of ducts.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129238840","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the rapid development of URT in major cities, sustainable development has been paid more and more attention. In the process of new urbanization in China, the location of URT station no longer consider only the traffic demand and passenger flow, but also the connection with the regional transportation network, harmonious neighborhood environment and reasonable layout of land use. This paper presents a bi-level multi-objective model of location of URT station, which integrated land use layout and regional transportation network. A max-min ant system (MMAS) algorithm integrated with the Frank-Wolfe algorithms is proposed to solve this NP-Hard problem. The effectiveness of the model and algorithm is verified by a case study of the east area of Guang'an City, and the superiority of the scheme generated by the model is shown by comparative analysis.

The system loads the global image data and 3D models information of Google map through Cesium system. To quickly load the 3D models information, the system adopts 5G network to receive and send the data, and continuously sends the data of the automatic identification system (AIS) installed on the ship to the remote-control terminal through 5G network. Cesium on the remote-control terminal according to the received information to carry out 3D rendering of the controlled ship and other ships, thus generating the twin vision of the controlled ship in real time. To achieve the purpose of fast remote control, the remote-control terminal sends control signals to the controlled ship through the 5G network. When the controlled ship receives the signals, it starts corresponding actions immediately. At this time, Cesium will draw the twin visual images of the controlled ship in real time according to the AIS data received by the remote-control terminal. The remote-control terminal continuously receives AIS data and sends ship control signals through 5G network, and the CESIUM system can complete the remote rapid control of the ship by drawing the twin visual images of the controlled ship in real time, which enables the remote controller to grasp the dynamic information of the ship in real time.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122273930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the factors like the limited dimensions, some channels are difficult to meet the needs of free navigation for large ships, which causes intermittent congestion in waterways, restricting the smoothness of the traffic flow, especially in large port waters. In this paper, the ship traffic in restricted channels is divided into the regular traffic flow and the fault-caused traffic flow according to the occupation of channel resources by ships. Based on the assumption, the intermittent relative fault fairway system model is constructed, and the simulation experiment is conducted by taking the “Tiaozhoumen channel” in “Zhoushan” waters as a case study. The results show that the model can well reflect the real-time utilization of waterway under various traffic density. The simulation model has significant theoretical and practical meanings for the effective organization of the overall traffic flow, which can be extended to be applied to similar types of busy and restricted channels.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121201780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the paper focuses on removing mismatches from putative matches by investigating the idea of motion consistency. This paper converts the feature matching into an outlier detection problem based on the converted spatial distance matrix. The classic anomaly detection method LOF is adopted to detect the outliers so that the false matches can be identified and removed. The images for experiments are obtained from cameras mounted on a vehicle and roadside infrastructure. Experimental results demonstrate that the proposed method achieves 88.14% average precision, which is the highest among the other two methods.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122606536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
