Snížení doby jízdy v městské dopravní síti pomocí lokálního směrování
Přibyl Ondřej; Maia Pereira André; Dieckmann Claudia
2019 - English
The thesis explores the concept of local level routing, where vehicles receive either travel times or route advice based on accurate short-term traffic conditions to reroute themselves throughout a network. We focus on developing a system to provide time-dependent road travel times considering information of signal timings, queue lengths, road closures and vehicle arrivals, in which traffic controllers model the movement of vehicles and share their knowledge about the traffic amongst themselves as a flexible centralized or distributed system. Our motivation is to reduce travel times, avoid congestion and balance the load of vehicles throughout the network. In order to achieve this, we first analyse how similar route guidance systems estimate travel times and define optimal routes. Then, we study possible solutions for the optimal route problem, specially shortest-path algorithms, and we defined the necessary inputs for the chosen algorithm type. After that, we research methods for estimation of discrete time-dependent travel times and decide to propose an event-based traffic theoretic model that models the driving behaviour of vehicles and cope with the restrictions of communication bandwidth between traffic controllers, the necessity of certain degree of prediction, and running time in larger networks, while feeding an deterministic queueing model that ensures estimations within a horizon of planning. We describe the functionality of our proposed system and evaluate it through simulations of a real-world scenario for several penetration rates, comparing it against the best, worst and current situations cases. Finally, we discuss the performance and future work for our local level routing system.The thesis explores the concept of local level routing, where vehicles receive either travel times or route advice based on accurate short-term traffic conditions to reroute themselves throughout a network.

Technologie iBeacon a její využití pro osoby se specifickými potřebami
Krčál Jan; Kochkurov Dmytro; Vaniš Miroslav
2019 - English
V této práci navrhujeme systém využívající iBeacon pro vnitřní polohování. V tomto systému iBeacon dokáže přesně nalézt místo, kde je uživatel ve vnitřním prostředí, a poskytne mu potřebné pokyny pro další pohyb. Naším cílem je poskytnout přesnější a efektivnější bezdrátový indoorový navigační systém využívající signály Bluetooth s nízkou spotřebou energie.In this thesis we propose a system utilizing iBeacon for indoor positioning. In this system, iBeacon can accurately locate where the user is in an indoor environment and give him/her required instructions for further movement. We aim to provide a more accurate, effective wireless indoor navigation system using Bluetooth Low Energy signals.

Návrh multidetektoru pro integraci různých dopravních senzorů
Langr Martin; Posekaný Lukáš; Scháno Martin
2019 - English
Diplomová práce se zabývá zkoumáním možností integrace senzorů a detektorů použitelných v dopravním odvětví. Velký důraz je kladen především na definování požadavků na senzory a detektory použitelné v systému Multidetektoru. Stěžejním bodem je definice Multidetektoru a to jak z hardwarového tak softwarového pohledu. Systém vytvořený dle zásad této práce je využitelný jak pro dlouhodobé a krátkodobé dopravní průzkumy, tak i pro rozsáhlejší telematické systémy. Navržené požadavky na Multidetektor jsou ověřeny v laboratorních i reálných podmínkách.Diploma thesis deals with the possibilities of sensors and detectors integration for transportation environment. Great effort is placed on defining the requirements on sensors and detectors usable in the Multidetector system. The main part is the Multidetector definition, both from the hardware and software point of view. A system built on the principles of this work would be usable both for long-term and short-term transport surveys and for larger telematic systems. The proposed Multidetector requirements are tested in both laboratory and real-world conditions
