Я новичок в SUMO и Traci4J, однако мне интересно научиться использовать эти инструменты. Я столкнулся с проблемой при запуске практически чего-либо на Traci4J. При выполнении nextSimStep() для объекта SumoTraciConnection я встречаюсь с ошибкой
it.polito.appeal.traci.TraCIException$UnexpectedData: Неожиданный идентификатор команды/состояния: ожидалось 164, получено 2
Я не могу найти причину этого, я пробовал это на 2 машинах с чистой установкой последней версии SUMO, последней версии Traci4J и Java SE 1.7.
Основной метод
public static void main(String[] args) {
SumoTraciConnection sumo;
sumo = new SumoTraciConnection(URL_TO_SUMOCFG, (int) System.nanoTime());
sumo.addOption("start", "1");
try {
sumo.runServer(true);
sumo.nextSimStep();
sumo.close();
}catch(IOException | InterruptedException e) {
e.printStackTrace();
}
}
