【问题描述】：

我使用的是 Googleway 包，两者之间没有任何区别 “悲观”、“乐观”和“最佳猜测”以及提及“驾驶”、“步行”或“骑自行车”模式时的结果相似。也许我的代码错了：

google_distance(origins = "place Viarme 44000 nantes",
                             destinations = "rue de strasbourg Nantes",
                             mode="driving",
                             departure_time=heure_dep,
                             traffic_model='best_guess',
                             key = key,
                             simplify = T)
google_distance(origins = "place Viarme 44000 nantes",
                             destinations = "rue de strasbourg Nantes",
                             mode="bicycling",
                             departure_time=heure_dep,
                             traffic_model='best_guess',
                             key = key,
                             simplify = T)

谢谢
