Experimental workplace for research of car speed limiters
Kubát, Michal ; Možný, Radek (referee) ; Pokorný, Jiří (advisor)
The bachelor’s thesis deals with the issue of remote vehicle speed limitation. The aim of this work is to develop an experimental workplace where the speed limitation using connection to CAN bus will be tested. In the theoretical part, a research on existing solutions of speed limiters is conducted and their protocols and technologies are described. The theoretical part also includes a research and description of possible threats and attacks on technology ITS-G5. The practical part deals with the development of the experimental workplace that consists of an OBD-II simulator and a transmitter. The OBD-II simulator includes Arduino UNO and add-on modules, its communication is realised via CAN bus. Transmitter includes Arduino NANO. Then, a wireless communication between a transmitter and an OBD-II simulator on 433 MHz and the wireless speed adjustments are developed. Finally, the IVIM message is designed and implemented for car speed limitation. Its structure was selected according to ISO standards for communication in ITS-G5 technology. The implementation of this message was tested on an OBD-II simulator. On the whole, a complete experimental workplace was assembled, and its manual was created.

Emulation of infrastructure unit for inteligent transport system
Giertl, Juraj ; Krajsa, Ondřej (referee) ; Balík, Miroslav (advisor)
The thesis deals with the study of communication models for cooperative intelligent transport systems and the development of the application used for testing. The ETSI ITS-G5 and IEEE 1609.x DSRC/WAVE comunication stacks were compared to standartizes layered ISO/OSI reference model. The basic principes of comunication in inteligent transport systems are described for each model. Besides that the common messages structures for defining alert messages, the intersection geometry and trafic lights signals are described in further detail. Based on these structures and other requirements, an application is created that allows easy definition of alert messages, intersection geometry and its traffic light states.

Emulation Of Infrastructure Unit For Inteligent
Transport Systém
Giertl, Juraj
This article describes a characteristics of Cooperative Intelligent Transport Systems (C-ITS) and development of an application used to emulate Road Side Unit (RSU) for proof of concept and testing purposes. Application enables users to easily define common messages used in C-ITS such as intersection geometry and it’s traffic lights signals and phases.
