The goal is to ensure absolute transit priority without heavy sacrifices from the general traffic. To achieve the goal, a Bus Priority Lane (BPL) is designed. The BPL is open for general traffic if needed. To implement the BPL, the proposed TBC controller would control whether and how general traffic accesses the BPL so that the sacrifice of general traffic is minimized. The proposed TBC controller is evaluated through comparison against the non-control baseline that ensures absolute transit priority with a Dedicated Bus Lane (DBL). Sensitivity analysis is conducted under different congestion levels. The results demonstrate that the proposed TBC controller outperforms the non-control baseline in terms of throughput benefits.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"12 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":"114969265","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}

From a realistic perspective, the asymmetric lane changing rules of right-lane preference are adopted for trucks, and the symmetrical lane changing rules are adopted for cars. Particularly, the characteristics of the tunnel is considered. The flow-density relationship obtained from the numerical simulation is basically consistent with the measured data. The unbalanced utilization of two lanes are captured from the spatial-temporal diagrams, and the trucks' effect on the cars' lane-changing behavior is reproduced. Furthermore the influence of Jiaodong'ao Tunnel on the traffic state of its upstream section gradually expands with the increase of the density. The properties of average velocities are studied with the variation of densities and tunnel positions, and the underlying mechanics are analyzed. The results will provide a theoretical reference for the traffic management and optimization of tunnel sections.","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":"123085474","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}

Designing an efficient feeder-bus network is essential for improving metro hubs’ distribution capacity. This paper divides the operation of the flexible feeder bus system into two stages. The first stage is to cluster travel demands with similar spatiotemporal characteristics, and then construct RLMP, SPS problems by using the column generation algorithm, which can reduce system travel cost and complete vehicle route planning at the same time. In the second stage, the mixed decision optimization of vehicle service attributes is carried out based on the reverse auction algorithm, which can minimize its impact on community bus and meet the demands of flexible bus operation. Finally, based on the bus operation data of three community bus routes near a subway station in Chengdu, it's verified that this model has good effects both on operational efficiency and benefits.","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":"127342645","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}

As the collision accident in the process of ship pilotage operation will cause large losses, it is necessary to analyze the risk of ship pilotage. Based on the establishment of the HFACS model of collision accidents for ship piloting operations, this study combined with Bayesian network analysis methods to quantitatively analyze the human errors during ship piloting. First, according to the characteristics of ship pilotage operations, the HFACS model of ship pilotage collision accidents is established. Secondly, rely on expert knowledge to analyze the risk factors in the HFACS model and establish a Bayesian network model for the risk assessment of ship pilotage collision accidents. Finally, combined with ship pilotage accident data and other subjective data, through Bayesian network reasoning, a quantitative assessment of the risk of ship pilotage collision accidents in Shanghai Port was carried out, and the main risk factors and risk casual paths in different stages of ship piloting were analyzed.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"58 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":"124839408","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, it is of great necessity and significance to realize the monitoring failure of ship's main engines in order to ensure that they can work properly. In view of this, this research proposed a method for the online monitoring piston ring wear of marine main engines based on the magnetic sensor technology. To verify the proposed method, a piston ring wear test bed was built, and the wear test of piston ring of two main engines with different cylinder diameter was carried out accordingly. Meanwhile, the magneto resistance signals of the two piston rings in different wear conditions were collected and analyzed comparatively. The results show that, firstly, both of the wear conditions of the two piston rings have a one-to-one correspondence with the characteristic values of the magneto-resistance signal; secondly, with the increase of the wear volume, the peak value of the magneto resistance signal shows an upward trend, thus verifying the effectiveness and adaptability of this method in terms of online monitoring wear of piston ring. The proposed method has the advantages of online, fast response and convenient use. This research provides a good reference for the whole-life monitoring of piston rings of main engines and the condition-based maintenance of main engines on board ships as well.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"44 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":"125552925","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 solve above problems, this article designs the storage structure and partition strategy of ship trajectory data, and builds attributes multilevel index and H3 spatial index on ship traj ectory data based on ClickHouse database, which not only achieves spatiotemporal query based on the oval, round, and arbitrary polygon area, and improve the efficiency of the spatiotemporal query; At the same time, the data storage space is reduced, so that a common server can manage 10 billion ship trajectory data.
