Autonomous valet parking technology is available for safe and quick parking operations without a driver, and improving the driving convenience while greatly reducing the probability of parking accidents. A path planning method of autonomous valet parking in parking lots mixed traffic scenarios is proposed in this paper to resolve the following issues presented in the existing autonomous valet parking systems, that is, low efficiency of global path planning and low success rates of local obstacle avoidance. First, the parking lot traffic scenario model is established and analyzed. Secondly, a global path planning method based on Floyd algorithm is proposed and optimized. Then, the obstacle avoidance path is decoupled laterally and longitudinally based on the fifth-order polynomial in the Frenet coordinate system, and the optimal local path is screened out through the coupling loss function and defined constraints. Finally, a simulation scenario was built to verify the path planning method studied in this article. The results show that the autonomous valet parking path planning method studied in this paper can achieve good results and has strong robustness.","PeriodicalId":116712,"journal":{"name":"Frontiers of Traffic and Transportation Engineering","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125087308","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}

While many agricultural products supply chains are fully engaged in traditional retail channels, they are also generally opening online sales channels, thus forming a dual-channel circulation mode of farm products in which conventional and online retail channels coexist. Due to the high overlap between the two sides in selling products and target users, the potential conflicts in the dual-channel supply chain of agricultural products have become increasingly prominent. Under the guidance of evolutionary game theory, this paper analyzes the collaborative evolution law of supply chain enterprises under the penalty mechanism. By simulating the game process of cooperation between the two parties, it is found that setting a reasonable punishment mechanism can reduce opportunistic behavior. It can not only enrich and expand the research horizon and depth of the dual-channel supply chain of agricultural products but also have important theoretical and practical significance for promoting the cooperation of the dual-channel supply chain of agricultural products, realizing the resource sharing and complementation of the two channels, and improving the benefits of the whole supply chain.","PeriodicalId":116712,"journal":{"name":"Frontiers of Traffic and Transportation Engineering","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125575387","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 timely eliminate the terrible influence of incidents, the indirect incident detection method is designed and presented based on the actual data of the segment from the Lingdian interchange to the Tangwang interchange hub of the Jinan-Guangzhou expressway in this paper. Firstly, the existing data from diverse detection systems are collected and integrated into a unified format. Then, an actual-data-based simulation experiment is achieved to offer the required information to the indirect incident detection method through VISSIM. On this basis, a series of parameters are constructed to identify the mutation of traffic operation from multi-dimension. Finally, the indirect incident detection method is trained to recognize the mutation of traffic and classify the normal scene and incident scene with LightGBM. Compared to KNN, RF, and SVM, the LightGBM has an excellent performance on incident identification, with a 98.6% accuracy, a 100% precision, an 88.9% recall, and a 94.1% F1 score.","PeriodicalId":116712,"journal":{"name":"Frontiers of Traffic and Transportation Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132501861","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}
