Thus, the methods of the intelligent control of vehicles traffic have to answer the growing demand. Optimization of traffic signal plans is an important step in this direction. Well-tuned traffic lights schedule augments the efficiency of vehicles flows processing. The research in intelligent traffic signal control helps to significantly improve a traffic situation, reduce the average vehicles waiting time and increase the average speed in the road network.In this study, we propose different configurations of a genetic algorithm to find an effective traffic lights schedule on the real road network. This heuristic evolutionary algorithm is known to cope well with different kinds of optimization problems. For application part of our research, we consider a complex segment of the street network in the city of Novosibirsk, Russia. Using a microscopic traffic simulator, SUMO, we model a corresponding road map fragment. The obtained model serves to evaluate the solutions of the traffic scheduling problem. We analyze the performance of the proposed genetic algorithm with different parameters and discuss the results of numerical experiments considering three different objectives functions which reflect traffic congestion. We show that the proposed approach can be applied to increase the quality of the traffic lights schedule, reducing traffic jams.","PeriodicalId":288547,"journal":{"name":"2019 15th International Asian School-Seminar Optimization Problems of Complex Systems (OPCS)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130149617","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 inverse problem is solved based on a sequence of direct initial-boundary value problems, each of which can be a resource-intensive interdisciplinary problem described by a system of multidimensional differential and/or integral (and/or discrete) equations in multi-scale computational domains with multi-connected piecewise smooth geometric configurations of boundaries and contrast material properties of multiphase media. This includes, in particular, the actual problems of surrogate optimization. The functional core of the ICE is focused on a high-performance support of all major stages of a large-scale computational experiment, including geometric and semantic modeling, generation of computational grids, approximation of initial equations, solution of algebraic problems, optimization algorithms for solving inverse problems, post-processing and visualization of results, decision-making on the results of the study. Technical requirements for the ICE involve a flexible expansion of the models and methods used, adaptation to the evolution of computer platforms, effective reuse of external software products, coordinated participation of different teams of developers and focus on a broad demand of the end users from different industries. These qualities are designed to provide a long life cycle and a qualitative increase in productivity in the development and application of the new generation software.","PeriodicalId":288547,"journal":{"name":"2019 15th International Asian School-Seminar Optimization Problems of Complex Systems (OPCS)","volume":"63 3-4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114046050","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}
