Meanwhile, average passenger trip distance are becoming much longer yearly. But not enough is known about passengers' performance and evaluation of the four typical long-distance travel modes, namely, HSR, ordinary train, plane and coach because previous studies have mainly focused on inner-city travel. In this paper, an evaluation index system was established, including safety, economy, efficiency, comfort and punctuality. The survey data were collected and the Analytical Hierarchy Process (AHP) technique was applied to investigate the transportation performances of the above four mode. The results revealed that ordinary train was the most competitive mode followed by HSR, coach and finally plane. Furthermore, the paper provides detailed findings and implications on the competitiveness of each mode over different attributes. This study may help the establishment of public transportation resource allocation and service market in the long-distance.","PeriodicalId":389628,"journal":{"name":"2015 International Conference on Transportation Information and Safety (ICTIS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125541329","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}

To ensure the navigation safety and legal right of crew, it is of great necessity to re-evaluate the minimum safe manning standard of engine department in such area. By applying on board function model, the functions of engine department, which include sub-functions such as main engine operation, auxiliary equipment operation, general operation and daily management, are recognized. Based on statistics of questionnaires, the frequency of on board assignment, crew rank and time needed for completion of assignment are determined and based on which the number of manning of engine department are calculated with different levels. Then the manning standard of engine department in The Three Gorges Reservoir Area are obtained, such as ship with main engine power between 500kW and 1500kW and 10 hours or more continuous working time should be manned with one chief engineer, one second engineer, one third or fourth engineer and one oiler.","PeriodicalId":389628,"journal":{"name":"2015 International Conference on Transportation Information and Safety (ICTIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126430871","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}

An inland cruise ship is chosen as a research object, the wind loads on the ship including longitudinal and transverse forces and the yaw moment are calculated in wind angle of 0-180° by using CFD method, and then the numerical result is compared with those from empirical formula calculations such as Fujiware method, Blendermann method and Isherwood method. On this basis, the numerical flow field of the ship is analyzed. The result shows that wind load coefficients vary greatly with the coming wind angles; with the results from the four methods, it is concluded that the numerical calculations agree with Blendermann method very well, while Isherwood method has large discrepancy with the rest of the three methods. It should be mentioned that the wind moment could be obtained according to actual wind environment by using the method presented in this paper which could offer help for ship designing and stability assessing and the pressure distribution chart of the ship could provide reference for the optimal design of the superstructure of the ship by the CFD method used in this paper.","PeriodicalId":389628,"journal":{"name":"2015 International Conference on Transportation Information and Safety (ICTIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126072083","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}

A vehicle recognition system based on laser scanning point cloud data is designed in this paper. With this system we can accurately acquire 3D point cloud data of vehicles, and preprocess the point cloud original data with the methods including coordinate transformation and median filtering. On the basis of the traditional vehicle features, the variance of vehicle top height is proposed as a feature quantity of vehicle. In addition, we adopts GA-BP neural network as a vehicle type classifier and select appropriate parameters according to the optimal parameters Schaffer recommended such as mutation probability. By analyzing the experimental results, the chromosome fitness function is optimized for the purpose of accelerating the convergence speed of Genetic Algorithms. The result of experiments and its application indicates that these features and the optimized GA-BP neural network selected by this paper have advisable performance on different kinds of vehicle recognition.","PeriodicalId":389628,"journal":{"name":"2015 International Conference on Transportation Information and Safety (ICTIS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130448259","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}
