Sementes aleatórias em modelos de transporte
Este artigo, escrito por Tessa Hayman, especialista de produto, explora as fontes de estocasticidade em experimentos no Aimsun Next e como controlá-las. Discute como a incerteza é um aspecto importante a ser considerado em modelos de transporte e como a estocasticidade pode ser controlada através do uso de sementes aleatórias. O artigo explica as diferentes sementes aleatórias presentes no Aimsun Next, incluindo a semente principal, semente de geração de veículos, semente de atribuição de veículo, semente de transporte público e semente de gerenciamento de tráfego, e como cada uma pode ser controlada para remover a estocasticidade. Além disso, o artigo apresenta exemplos de como verificar o efeito dessas alterações em modelos de transporte.
Avaliando os impactos ambientais das Zonas de Baixa Emissão com o Aimsun Next
Avaliação dos impactos ambientais das Zonas de Baixa Emissão (LEZ) com o simulador Aimsun Next. Com o objetivo de melhorar a qualidade do ar nas cidades, as LEZ restringem a circulação de veículos poluentes, aumentando a eficiência na regulamentação da poluição atmosférica. Confira a nota técnica nº 75 de novembro de 2022 e saiba mais sobre o modelo de emissão de Londres e outros modelos de emissão disponíveis no Aimsun Next.
Executando uma simulação no Aimsun Next conectado ao SCATSim.
O post discute como reproduzir a operação do sistema de controle de tráfego adaptativo SCATS em uma simulação mesoscópica ou microscópica no Aimsun Next, conectando-se ao SCATSim. O SCATSim é um conjunto de módulos de software desenvolvidos pela RMS para emular uma implantação real do SCATS. Para realizar essa troca de dados, é essencial que os objetos do Aimsun Next, como controladores, sinais ou detectores, correspondam aos objetos do SCATS correspondentes. A correspondência pode ser feita automaticamente usando a Interface ITS do SCATS ou manualmente abrindo o aplicativo Access do SCATS e replicando os mesmos objetos e identificadores no software Aimsun Next.
