Influnce of Driving Style of a Tram Driver on the Tram's Energy Consumption

A typical feature of city tram transportation is increasing its effectivity. The main effort of public transportation companies is seeking savings for decreasing the energy intensity of mass transit. During operative measurement of power consumption in the tram cars it was found that on the whole the tram energy consumption have well-known influences such as tram occupancy, use of heating etc., and less known factors such as e.g. driving style of driver. We would like to estimate how much more energy is consumed by aggressive driving style of driver. Because it is impossible to ensure the same conditions at passing the same track, we concentrated on devising a tram car model that quantifies the difference of consumed energy in case normal driving style of the driver and in case of dynamic driving style of the driver. Because we use mathematical model, we can set the other conditions such as vehicle occupancy, the number of accelerations, stoppings etc. on the same values.
