Metrobus Line is a strategic dedicated transit bus line planned by Istanbul Metropolitan Municipality, which crosses the İstanbul city from Asia to Europe. Its length is about 52 kilometers and there is more than 500 busses in 24h service, which enables mass transit of about 800.000 passengers daily between two continents. In public transportation, the fuel cost is the most important part of the operating cost, which is 125 Million Euro for İstanbul Municipality. On the other hand, the amount of greenhouse gas “CO2” which is emitted to the atmosphere from public transportation is directly related to the amount of fuel consumed during the operation, which should be lessened for greener environment. Therefore, predicting and optimizing the effects of different bus cruises on fuel consumption over this route is important for establishing more economic and cleaner public transportation.
In this context, there are some methods that can be used for calculating the fuel consumption during a specified driving cycle. Among these methods, dynamic programming tools are advantageous with their easy and flexible application and high accuracy. In order to construct a simulation model that will be representative for real world fuel consumption of Metrobus line, AVL CRUISE + IPG Truck Maker program co-simulation was realized. A detailed drive train model of Mercedes Capacity articulated bus was created by using AVL Cruise by using the engine dynamometer data. The vehicle model of the bus and the road model of İstanbul Metrobus Avcilar-Zincirlikuyu route, which consists of 26 stations, was created by using IPG Truck Maker. The co-simulation model was validated with the experimental data collected on the real route with AVL KMA Mobile. Simulation and experiment results were post processed by using MATLAB. The model results showed ±1% accuracy on the specified route compared to real-world measurement, which means that the model can be used for further optimization works.
