This paper deals with a new energy saving urban transportation system called "EcoRide". The vehicle that does not have on-board driving devices runs using potential energy by the application of roller coaster technologies. The new urban transportation system is needed to be considered of ride comfort in traveling direction for using the vehicle system as public transportation system. Therefore, this paper proposes speed control design approach of vertical track geometry. At first, dynamic characteristics of energy saving urban transportation system was brought out. Then, speed control design approach was proposed by using dynamic characteristic charts.
