Abstract (en)
[origin: EP1719687A2] Method involves solving of acceleration phase by differential equation v'(t) = av2>(t)+bv(t)+c, with speed v(t) and parameters a,b,c depending on the time t, by formulae. These formulae are to be used with constant speed or constant braking deceleration in order to determine travel time for train travel. During positive acceleration v'(t) greater than 0, it examines, whether the sufficient distance is there to attain maximum permissible speed. During negative acceleration v'(t) less than 0, it is examined, that whether the train eventually comes to a standstill and the point of time of the standstill and thereby mileage distance is determined. During the steady travel v'(t)= 0, a break-down speed of vo is maintained. Basically a specific limitation is allowed for a exit speed by a timely application of a braking device.
