Intelektinių transporto sistemų poveikio eismo saugumui vertinimas ir jų diegimo Lietuvos automobilių keliuose galimybių analizė / Evaluation of the Effect of Intelligent Transport Systems on Road Traffic Safety and Feasibility Analysis of their Implementation on Lithuanian Roads

Strumskys, Mantvydas 10 June 2014 (has links)
Baigiamajame magistro darbe siekiama nustatyti, kurios intelektinės transporto sistemos (ITS) labiausiai teigiamai veikia eismo saugumą automobilių keliuose. Šiam tikslui pasiekti darbe analizuojama esama eismo saugumo situacija Lietuvoje, apžvelgiamos ITS, taikomos užsienio šalyse ir Lietuvoje, tarpusavyje lyginamas jų poveikis atskiriems eismo saugumo rodikliams. Siekiant gauti tikslesnius vertinimo rezultatus atliekamas ITS poveikio eismo saugumui tyrimas apklausiant šios srities ekspertus. Tyrimo rezultatai apdoroti analitinio hierarchinio proceso (AHP) metodu. Išrinkus ITS, kurios labiausiai teigiamai veikia eismo saugumą, pateikiamos rekomendacijos dėl jų diegimo Lietuvos automobilių keliuose. Apskaičiuojamas ekonominis efektas įdiegus rekomenduojamas sistemas. Baigiamąjį magistro darbą sudaro įvadas, keturi skyriai, bendrosios darbo išvados bei 2 priedai. Darbo apimtis 125 puslapiai, 50 paveikslėlių ir 18 lentelių. Rašant baigiamąjį magistro darbą panaudotas 91 literatūros šaltinis. / The aim of the Master Thesis is to determine which intelligent transport systems are the most common to reduce accidents on the roads. To achieve this aim, the work provides an analysis of traffic safety on Lithuania roads and an overview of the ITS in the foreign countries, and Lithuania. ITS were compared with each other by their effect on individual safety performance. In order to get more accurate results of the evaluation of ITS impact on traffic safety, a research of experts’ interview was carried out. The expert questionnaire was created and results were evaluated by the method of Analytic Hierarchy Process (AHP). The recommendations of ITS implementation on Lithuanian roads were proposed. The economic effect of the introduction of the recommended systems was calculated. The Master Thesis consists of an introduction, four chapters, conclusions, and 2 appendices. It includes 125 pages, 50 images and 18 tables. 91 references were used.

Eismo įvykių miestuose fiksavimo GIS posistemė / GIS subsystem for accidents fixing in cities

Petkuvienė, Jovita 21 July 2004 (has links)
Final master work proposes accidents fixing in cities GIS subsystem which includes database and map. Two databases conceptual models are formed in scientific work. One of them is choosing for detail projecting based on an accident dim. One parameter (the number of pedestrian passage) in database is involved in addition, not from the accident dim. Record accidents of 2003 year are marked by points on the map of Zirmunai part in Vilnius. Parameters describing accidents are saving in attributes table. Data of accidents were taken from archive of Vilnius road police. GIS subsystem projecting process, usage opportunity and users are presenting in this scientific work.

Automobilių važiavimo greičio automatizuotų kontrolės sistemų vystymas Lietuvos automobilių keliuose / Development of Automation Traffic Speed Control Systems in Lithuanian Roads

Čygaitė, Laura 23 July 2012 (has links)
Baigiamajame magistro darbe apžvelgiama avaringumo Lietuvos Respublikos valstybinės reikšmės keliuose situacija. Darbe analizuojama automatizuotos važiavimo greičio kontrolės sistemos diegimo Lietuvos automobilių keliuose patirtis, pateikiama automobilių važiavimo greičio tyrimų Lietuvos keliuose analizė. Baigiamajame darbe nagrinėjami visuomenės nuomonės apie automatizuotos važiavimo greičio kontrolės sistemos poveikį eismo saugumui tyrimo rezultatai bei vandalizmo atvejai prieš stacionarius greičio matuoklius. Darbo pabaigoje pateikiamos išvados ir rekomendacijos. Baigiamojo darbo apimtis – 101 psl. teksto be priedų, 30 lentelių, 63 paveikslai ir 3 priedai. / In this Master Thesis an overview of the Republic of Lithuania accident rate situation on national significant roads are given. An analysis of automatic traffic speed control system implementation experience in Lithuanian roads and car speed research on Lithuanian roads are given in this final paper. Also a part of the work reveals research results of public opinion on automatic speed control system influence to traffic safety and cases of vandalism against fixed speed cameras. Conclusions and recommendations are given at the end of the paper. Master thesis consists of 101 pages pure text without appendixes, 30 tables, 63 pictures ant 3 appendixes.
