THE DISTANCE BEING IN MILES AND THE TIME IN HOURS, IT BECOMES A MILES PER HOUR, OR SPEED, FIGURE. IT HAS BEEN CALLED THE EFFECTIVE SPEED, BECAUSE IT MEASURES THE SPEED AT WHICH THE TRIP (OVER THE NETWORK) IS REALLY PROGRESSING TOWARD ITS DESTINATION, EVEN THOUGH ITS ACTUAL ROUTE MAY BE CIRCUITOUS OR CONGESTED. THUS, THE EFFECTIVE SPEED MAY BE ONE MEASURE OF AN OBJECTIVE CONCERNING SERVICE TO TRAVEL.
