Due to the extra running time supplements, the minimum headway can be further compressed by multi-step braking operation of trains during the phase of entering station. To find the theoretical minimum headway with the constraint of punctual arriving, an optimization model which take driving strategy as decision variable is constructed. A dynamic programming based searching approach is proposed to solve the optimization model.

A mode, i.e. “originating from stations outside downtown before a temporary stop at stations in the city center” is proposed in this paper, with an intention to make full use of capacity of the high-speed railway stations and lines. Besides the target regarding the capacity, another target related to maximizing the flow of high-speed rail passengers in the whole city is also used in the optimization model, intending to make the high-speed rail service convenient to the passengers in the whole city. Lpsolve in c # is used to solve the optimization problem. The proposed mode and its corresponding optimization model as well as the way of solving it is finally validated by the data from Shenzhen, China. The results show that the optimization problem can achieve its optimized train operation plan within 10s under the proposed mode, in which 80% of the capacity of stations and lines in Shenzhen can be utilized in a geographically balanced way. The proposed organization mode and model for checking its superior effects can function as a decision support for the expansion of terminal stations and lines.","PeriodicalId":112371,"journal":{"name":"2020 IEEE 5th International Conference on Intelligent Transportation Engineering (ICITE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121200534","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}

Using the “from coarse to fine” strategy, a double-layer hierarchical series combination classifier is designed. HGA-BP classifier with two-layer structure is used for pedestrian recognition. Firstly, the candidates are extracted by combining the basic characteristics of the target object shape, in order to quickly eliminate most of the non-target areas, and then use the advanced features of the target to identify the candidate target areas after the processing of the previous classifier. Through the experimental analysis, this method can better classify and identify pedestrians and other negative moving objects, and count the number of pedestrians in the whole traffic scene accurately.","PeriodicalId":112371,"journal":{"name":"2020 IEEE 5th International Conference on Intelligent Transportation Engineering (ICITE)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128078683","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, exploring high-precision and efficient prediction methods is still a challenge. To capture the spatiotemporal characteristics of traffic flow and accurately perceive the traffic state, a spatial and temporal combination (STC) model was proposed. The radial basis function neural network (RBFNN) was used to capture the spatial characteristics of traffic flow, while the clockwork recurrent neural network (CWRNN) was utilized to predict the temporal characteristics. The prediction accuracy of the model can be further improved by the result fusion based on the spatiotemporal feature prediction model. To verify the accuracy and robustness of the algorithm, the Beijing 3rd Ring Road speed data are used to compare with other models. The results show that the accuracy of the STC algorithm is better than benchmark prediction models at different service levels.","PeriodicalId":112371,"journal":{"name":"2020 IEEE 5th International Conference on Intelligent Transportation Engineering (ICITE)","volume":"82 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134304544","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}
