Otoyol ücretlerini hesaplama örneği
Aşağıdaki örnekte, ücretli geçiş kartı kullanıldığında bir rotadaki ücret bilgilerini tahmini fiyatla döndürmek için computeRouteMatrix yöntemi kullanılmaktadır.
Bu özellik, istekte belirtilen routes.travelAdvisory.tollInfo alan maskesi ile etkinleştirilir. Otoyol geçiş kartı, route_modifiers alanında belirtilir. Döndürülen geçiş ücreti, belirtilen geçiş tarafından kullanılan fiyatlandırmaya dayanır. Birden fazla geçiş belirtilirse en ucuz fiyat döndürülür.
