Exemplo 7 da Micro API do Aimsun Next:¶

Exemplo de uma conexão ANG (atualizando um atributo de veículo de simulação ANG)¶

Este exemplo mostra como criar um novo atributo "VehStatus" (como um inteiro) no objeto ANG Simulation Vehicle e, em seguida, definir um valor dependendo da seção onde o veículo está localizado (na seção 241 o atributo é definido como 1, enquanto na seção 250 é definido como 2).
