Based on the actual road operation data of 169 PHEV buses in six typical cities such as Beijing and Shanghai in 2018, this paper analyzes the use characteristics (including travel characteristics and charging characteristics) of PHEV buses by constructing the characteristic data set, and studies the calculation method of pure electric mileage proportion based on the use characteristics. One of the most important results is that the actual charging frequency of PHEV buses in China is low, the charging power is small, basically with no charging travel behavior characteristics, resulting in a significant reduction in utility factor, which will make the actual energy saving and emission reduction effect greatly reduced. The research reflects the use status of PHEV buses in typical cities of China, which can lay a foundation for the research on energy consumption and emission test methods of PHEV buses, and provide suggestions for the formulation of test methods and standards for energy consumption and emission of PHEV buses.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"99 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":"125980137","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}

One of the reasons that cause this problem is that these data need to be anonymized when shared and analyzed, which makes it difficult to link trips together to form trip tour. As a result, this study intends to propose a method to match users across transportation modes (bikeshare and metro in this study) making full use of the characteristics of the transfer behavior, and the matching results are further pruned based on time and space constraints. The results show that there is a strong correlation between bikeshare travel and metro travel, which is consistent with the results of previous studies. Two empirical formulas are obtained by fitting bikeshare users with different trip times to the matching results. The goodness of fit is 0.981 and 0.865, respectively, and the matching effect is good. At the same time, it also shows that the algorithm in this paper can better handle the matching of users with transfer and commuting behavior. This algorithm can provide important support for transportation planning and operation management of the urban transportation system.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"4 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":"126541978","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}

ART travels counterclockwise along its driving lane, and the external truck drives clockwise along its driving lane, so that the two vehicles no longer share the same lane. Therefore, isolated lane layout can improve the efficiency of transportation. Finally, we build the simulation model of the isolated lane layout in automated container terminal yard through AnyLogic software. The performance of the isolated lane layout and the traditional automated container terminal layout which blocks are vertical to the quay shoreline is evaluated. Compared with the vertical layout, the simulation results show that under the isolated lane layout, the average waiting time of the ARTs and the external trucks could be reduced by 85% and 75%, the average queue length is reduced by 80% and 41%, and the operation efficiency of the yard is improved by 4%.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"455 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":"124316077","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}

The IoD in this paper includes the EV terminals, charging piles terminals, smartphones, etc., which collect and upload data from EVs and users. With the data collated from the terminals, the cloud platform could perform battery health and safety analysis with historical data, and help to improve the safety of the EVs. This paper discusses the services that the cloud platform can provide in each scenario, and cataloged the potential safety service into several groups.

This lane change path planning scheme is formulated as an optimal control problem according to the three-segment lane change model. Then the B-spline curve is applied to smooth the path. The core contribution is that a method based on hybrid intelligent algorithms is proposed to solve the optimal control problem fast and stably. First, an extended differential evolution is proposed to quickly provide a tough initial guess for the subsequent search. Then two criteria are set to judge whether the tabu search can start. After satisfying them, tabu search seeks a better solution based on the initial guess. Finally, a 1000 cycles simulation experiment is run to verify its stability and real-time performance. Simulation results show that the average time consumption is 0.7417ms, the success rate is 99.97% and the average maximum curvature is 0.13947m−1. Besides, it is also compared with other intelligent optimization algorithms as well as the optimization solver MIDACO. The result shows that our method surpasses other algorithms in comprehensive performances.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"107 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":"123240073","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}

Considering the URT stations' failure severities, a repair strategy which is called the model repair strategy is proposed to determine the repair sequences of failed stations under disturbances. The model repair strategy aims at minimizing a URT network's performance loss and maximizing repair efficiency, and it is constrained by the amount of repair resource and repair capacity. The model repair strategy is solved by the non-dominated sorting genetic algorithm. Finally, the repair strategies for the Chengdu subway network under random and deliberate attacks are calculated by the model and staci repair strategies. The results indicate that deliberate attacks are more harmful to the Chengdu subway network than random attacks. Compared with the static repair strategy, the model repair strategy has greater repair efficiency. It can effectively reduce a URT network's performance loss caused by the disturbances. The operators are encouraged to apply the model repair strategy to determine the repair sequences of failed stations.","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":"131785625","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}
