PT Journal AU Opava, J TI Relation between Running Time and Energy Consumption SO Transactions on Transport Sciences PY 2009 BP 1 EP 8 VL 2 IS 1 DI 10.5507/tots.2009.001 DE Electric railway; running time; energy consumption; energy saving; energy navigation instrument. AB The traditional solution of energy efficiency has, up to now, lain in research into the design of electric traction equipment and utilizing the latest findings in electric materials, semi-conductors, driving and regulating aggregates and production technologies. Economical and ecological requirements create impulses for searching for different routes leading to the energy efficiency of electric railway operation, just like in other fields of technology. Research in this field has embarked on searching for unconventional options, characterized by the examination of the relationship between running time and energy consumption. This approach defines a rational method of the train guiding and can deduce ideal requirements for creating timetables. This paper elaborates on a particular approach to a given problem and introduces achieved outcomes. ER
