With the increase of vehicles in large urban centers, there is also an increase in the number of traffic jams and accidents on public roads. The development of a proper Intelligent Transport System (ITS) could help to alleviate these problems by assisting the drivers on route selections to avoid the most congested road sections. Therefore, to improve on this issue, this work proposes an architecture to aid an ITS to detect, analyze, and classify the traffic flow conditions in real time. This architecture also provides a control room dashboard to visualize the information and notify the users about the live traffic conditions. To this end, the proposed solution takes advantage of computer vision concepts to extract the maximum information about the roads to better assess and keep the drivers posted about the traffic conditions on selected highways. The main contribution of the proposed architecture is to perform the detection and classification of the flow of vehicles regardless of the luminosity conditions. In order to evaluate the efficiency of the proposed solution, a testbed was designed. The obtained results show that the accuracy of the traffic classification rate is up to 90% in daylight environments and up to 70% in low light environments when compared with the related literature.
Simulação é a abordagem mais adotada para avaliar redesveiculares, pois permite avaliar novos protocolos e infraesturutras de forma completa, ou seja, avaliar as novas ferramentas em todos os cenários possíveis. Para que essas simulações possam obter um resultado confiável é necessário que o ambiente de simulação utilizado se aproxime de um ambiente real. Portanto, os parâmetros de rede bem como o modelo de mobilidade tem que representar a topologia de rede real com alta fidelidade, ou seja, além dos parâmetros de rede terem que coincidir com os parâmetros e comportamentos dos equipamentos reais, o modelo de mobilidade também tem que representar a mobilidade do mundo real. Com isso em mente, foi proposto uma ferramenta que coleta o percurso dos veículos em tempo real de uma cidade na qual permitirá ao pesquisador utilizar esses dados em seu ambiente de simulação.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
