However, in order to achieve the goal of unmanned inland ships, the independent navigation of the ship should be carried out in the typical river section including the bridge area. This paper takes the Wuhan section of the Yangtze River as the research object of the bridge waterway. the track is restored based on the ship’s AIS information. Combined with the navigation rule of ships passing through the bridge, this paper analyzes the track belt characteristics of ship crossing bridge, and establishes a track segment scale model suitable for ships to navigate safely across the bridge. According to the actual situation of ship crossing the bridge, taking wind, current disturbance and shallow water effect into consideration, the mathematical model of MMG three-degree-of-freedom maneuvering motion of inland river ship is established. After setting up the track segment scale model and ship maneuvering motion model, the differential evolution algorithm is applied to ship track control. When simulating the track control of ship's upstream and downstream bridges, two groups of experiments are further divided into the hydrostatic environment and the external disturbance environment. The control effects under the hydrostatic environment and external disturbance are compared and analyzed. The results show that the differential evolution PID track controller can make the ship safely pass through the bridge area no matter it is going upstream or downstream. This study can be used as a supplement to the theoretical system of pre-control of ship-bridge collision to promote the development of navigation safety assurance technology in bridge area.","PeriodicalId":325712,"journal":{"name":"2019 5th International Conference on Transportation Information and Safety (ICTIS)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114933483","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}

Studying the characteristics of the Yangtze River on waterway freight transportation plays a significant role in propelling the development of the Yangtze River transport network and releasing the transport potential of the Yangtze River. In this study, the data of ship visa in 2010 were used to conduct the OD matrices of different freight types. Then, freight desire lines of the YREB were drawn in TransCAD according to the OD matrices acquired. In addition, the freight relations and characteristics of each port and three economic circles in the YREB were analyzed. After that, this paper applies the freight distribution models such as gravity distribution models and the intervening opportunity models to analyze the distribution of coal and its products, steel and nonferrous metals respectively. In particular, the impedance function of the gravity distribution model include the inverse power function, the exponential function and the gamma function, then their parameters were calibrated. Finally, the value of Average Trip Length (ATL) and Trip Length Frequency Distribution (TLFD) were measured and compared with the value calculated, then the results indicated that the gravity distribution model based on an inverse power function was higher than the Intervening Opportunity (IO) models in the coincidence ratio, and the freight distribution matches this in the reality.","PeriodicalId":325712,"journal":{"name":"2019 5th International Conference on Transportation Information and Safety (ICTIS)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124597527","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}

This approach guarantees the traffic capacity during freeway reconstruction and extension and aims to optimize the traffic flow of a regional road network. The method is based on the status quo of the road network traffic flow, the feasibility of the road network diversion, and the rationality of the traffic organization of the key nodes. The various indexes of the road network that are affected by the reconstruction and extension are analyzed by considering the Shenshan Expressway as an example. The capacity model for an expressway reconstruction and extension project is established by considering the constraints of the regional road network, such as the road service level. The influence of the reconstruction and extension on the traffic capacity for the control nodes of the expressway is analyzed using the VISSIM software. The results show that the reconstruction and extension project negatively impacts the traffic operation status of the entire road network where the construction section is located. Using the proposed comprehensive evaluation method to determine the traffic operation status of the road network allows the feasibility of the bottleneck sections and the associated diversion schemes to be analyzed. This effectively alleviates the traffic pressure from the reconstruction and expansion sections through optimal use of the existing road resources.","PeriodicalId":325712,"journal":{"name":"2019 5th International Conference on Transportation Information and Safety (ICTIS)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130464518","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}
