Exemplo 9 da Micro API do Aimsun Next¶

Exemplo de Controle (Alteração dos tempos de fase)¶

Este exemplo mostra como usar funções da API do Aimsun Next para alterar os tempos de um plano de controle.

Baseia-se na rede do tutorial: Editing - Finished network. A API com as configurações atuais alterará os tempos do plano de controle "Control AM" para o nó 1541. Observe que o tipo do cruzamento controlado deve ser alterado de 'Fixed' para 'External'
