Когда я добавляю много транспортных средств , возникает ошибка значения ,особенно когда я использую сеть, кроме кольцевой сети.
Иногда , когда количество моих транспортных средств не слишком велико ,а длина сети велика ,ошибка не возникает.
Я не знаю, где возникает ошибка.
Какой код я должен изменить, чтобы избежать воспроизведения ошибки.
Может ли кто-нибудь дать мне какой-нибудь совет?
