From a technical point of view, in dangerous or emergency situation is very important motorcycle driver reaction and vehicle braking time. Motor-cycle deceleration parameters depend not only on the motorcycle brake system, but also on the driving experience. A significant influence on decel-eration the motorcycle has aerodynamic parameters, pavement type and condition, as well as the technical condition of the motocycle, shock absorb-ers, tire type and their technical condition. This article provides an analysis of the motorcycle longitudinal deceleration, braking modes of the mo-torcycle on a dry asphalt road surface. Motorcycle stopping – deceleration – acceleration efficiency issue, stopping in different modes. First ana-lyzed the dynamics of a motorcycle deceleration braking only the front wheel, then braked front and rear wheels and complex – then braked the front and rear wheels at the same time. The goal of experimental study is to determine the influence of braking modes intense fir motorcycle brak-ing deceleration when braking on dry road pavement, at three different braking modes, and set the braking path of change. Motorcycle decelera-tion in the longitudinal direction is an important parameter for analysis traffic accidents, for accident reconstruction process and the examination of motorcyclists technical possibility to avoid an accident. Pavojingoje ar avarinėje situacijoje techniniu požiūriu labai svarbus yra optimalus transporto priemonės stabdymas laiku. Motociklo lėtėjimo parametrai priklauso ne tik nuo motociklo stabdžių sistemos, bet ir nuo vairuotojo patirties. Didelę įtaką motociklo lėtėjimui turi aerodinaminiai parametrai, kelio dangos tipas ir būklė, taip pat motociklo techninė būklė, amortizatorių, padangų tipas ir jų techninė būklė. Šiame straipsnyje pateikiama motociklo išilginio lėtėjimo analizė, stabdant motociklą ant sausos asfalto kelio dangos. Motociklo stabdymo – lėtėjimo – pagreičio efektyvumas nagrinėjamas, stabdant skirtingais režimais. Pirmiausia analizuojama motociklo lėtėjimo dinamika stabdant tik priekinį ratą, paskui priekinį ir galinį ratus bei stabdant kompleksiškai – priekinį ir galinį ratus. Eksperimentinio tyrimo tikslas – nustatyti, kokią įtaką turi stabdymo režimai intensyviai stabdomo motociklo lėtėjimui stabdant ant sausos kelio dangos, trimis skirtingais stabdymo režimais ir nustatyti stabdymo kelio pokytį. Motociklo lėtėjimo pagreitis išilgine kryptimi yra svarbus eismo įvykių analizei parametras atkuriant eismo įvykio eigą ir nagrinėjant motociklo vairuotojo techninę galimybę išvengti eismo įvykio.

<p>A história do município de Conceição do Mato Dentro, localizado no Estado de Minas Gerais (Brasil), se confunde com a realidade de muitas cidades mineiras pertencentes ao ciclo da mineração, em especial o ouro durante o século XVIII. O município, que é um polo de atração de investimentos para a região, é marcado por um cenário social e econômico de forte expansão da atividade de exploração de minério de ferro e do turismo ecológico. Há, contudo, muita polêmica e indagações quanto ao efetivo papel da mineração para o desenvolvimento dos espaços onde ocorre: economias de base mineradora têm muito mais problemas do que vantagens para conduzir o processo de desenvolvimento econômico ou social? Limitam a capacidade de expansão de outros setores produtivos? É fator impulsionante no desenvolvimento? Afora as controvérsias sobre essa temática, o fato é que o empreendimento minerário gera impacto de muitas formas (positivos e negativos) nos municípios e regiões que se instalam e, por muitas vezes os dados oficiais censitários não mensuram essa dinâmica em curto prazo. Este artigo, ao avaliar o caso do município mineiro de Conceição do Mato Dentro, tem como objetivo analisar os possíveis impactos da atividade minerária na dinâmica demográfica e econômica local. Para tanto, foram utilizadas as bases extraídas do Censo Demográfico de 2000 e 2010 e da Relação Anual de Informações Sociais (RAIS 2006 a 2012), incluindo de outras instituições oficiais. Em geral, nota-se que as alterações observadas nos dados censitários não foram sensíveis à realidade atual, indicando, por exemplo, taxas negativas de crescimento e pequenos incrementos nos no fluxo migratório com destino ao município de Conceição do Mato Dentro. Contudo, dados mais recentes revelam um considerável crescimento no quantitativo da frota total (inclui ônibus, motocicleta, automóvel, caminhão, micro-ônibus), do PIB, da arrecadação municipal e de empresas e empregados ligados ao setor minerário, como nos setores da construção civil e do comércio e serviços. Estes dois últimos setores apresentaram um incremento relativo de 333% e 102% de 2006 a 2012, respectivamente.</p><p><strong>Abstract </strong></p><p>The history of the city of Conceição do Mato Dentro (CMD) is similar to the reality of many other mining towns at Minas Gerais state, mainly with the gold mining in the XVIII century. Nowadays the city is the center of investments in a region where the economy is based on ecological tourism and iron ore exploitation. However, there are a lot of controversy and questions about the actual role of mining in the development of the territory where occurs: economies based in mining have more problems than advantages to drive the process of economic and social development? Can the mining to limit the ability of expansion of other productive sectors? Or is it an propulsor factor to development? Aside from the controversy over this issue, the fact is that the mining activities generate impact (positive and negative) and, often, the demographic official census data do not measure this dynamic in the short term. This article, aimed to analyze the case of the mining municipality of Conceição do Mato Dentro, aims to analyze the potential impacts of mining activity in migratory and economic dynamics location. However, the data were extracted of the Demographic Census (2000 and 2010) and of the Annual Social Information (RAIS 2006-2012), including another official institutions. In general, it was noted that the changes observed in the Census data were not sensitive to the current reality, indicating, for example, negative growth rates and small increases in the flow of migrants bound for the municipality of Conceição do Mato Dentro. However, the more recent official datas demonstrate the considerable increase in the amount of the total fleet (includes bus, motocycle, car, truck and minibus), the GDP, the municipal levy and companies and employees related to the mining sector, mainly in civil construction and trade and services. The last two sectors demonstrated relative Increase of 333 % and 102% from 2006 to 2012, respectively.</p><p><strong>Keywords</strong>: Mining; Migration; Conceição do Mato Dentro/MG.</p>

This Master’s thesis deals with designing a measuring device that would record driver’s movements during dynamic riding states known as localization, and based on the recorded data creating a simulation in multi-body software. The first part reviews the current state of knowledge in the field of photogrammetry, sensors, and motorcycles’ characteristics. Moreover, the second part focuses on constructing the measuring device, practical aspects of data collection, processing, and evaluation in multi-body software.

This diploma thesis called Motorcycle Race Dynamics captures the development and development of motorcycles, a description of types, design elements and the techniques of riding a motorcycle. However, the aim of this work is to organize, perform and evaluate the measurement of braking deceleration and the crossing of motorcycles. Before separate data processing, a theoretical methodology for measuring transverse displacement and braking deceleration is proposed. This requires enough motorcycles, experienced riders, two cameras, a measuring instrument and precisely dimensioned lines. The lateral displacement and braking deceleration measurements are then performed and subsequently evaluated. Output of this work include, in addition to videos, an overview of transverse displacement times, or longitudinal deceleration output values gained from braking.

This thesis, within a long-term project at the Institute of automotive engineering at FME BUT, aspires to prepare a motorcycle for analysis of its dynamic riding behavior. A multi-body model of a motorcycle is created based on the measured parameters and a system for measuring driving conditions is designed. The necessary motorcycle parameters were measured using a 3D scanner and through experiments aided by computer technology and CAD software. This laid the foundation for the follow-up research and development work.
