The article describes the questions of experimental researches in road traffic and possible alternatives for the implementation of the experiment. Evolutionary planning is suggested as the basic planning of the experiment. Some results are given from the research of the main parameter -volume of traffic flows. Satisfactory management is far from optimal management and huge reserves are still available here. The problems of collecting data on the parameters of traffic flow have been studied by many researchers. In this article authors also tried in a certain way to enlighten a number of questions related to the implementation and planning of experimental researches in the field of road traffic.Keywords: parameters of traffic flow, methods for the implementation of the experiment, evolutionary experiment, planning of the experiment.
