You cannot specify a spread of absolute speeds, only a spread relative to the speed limit. Assuming your roads have an average speed o 50km/h this is how you define it:
--trip-attributes "departLane=\"best\" speedFactor=\"normc(1.4,0.2,1.2,1.6)\" color=\"255,255,255\"" --vehicle-class emergency Explanation: speeds are defined as a truncated normal distribution centered on 1.4 (70km/h) with a deviation of 0.2 (10km/h) and truncated at 1.2 (60 km/h) and 1.6 (80 km/h). Note, that the option --vehicle-class is needed so that all attributes are correctly assigned (the speedFactor normc defintion must get written into a vType) Am Mo., 6.
