Fluctuation in Motor-vehicle Traffic
Traffic counts occur on freeways and federal highways nationwide at the behest of the Federal Minister of Traffic, according to a uniform method and for comparable periods. They are undertaken by the respective state authorities, in Brandenburg by the Brandenburg State Office for Traffic and Road Construction, in Berlin by the Department of Traffic and Utilities, which is also responsible for the supplemental elevations in the remaining major street network.
As stated above, the seasonal, weekly and daily fluctuation in motor-vehicle traffic are of essential significance for the evaluation and projection of traffic counts. Thus, for example, in the winter months (January, February), at the sudden onset of winter (end of November and December), as well as in the summer vacation (July), the traffic volume recedes significantly (cf. Fig. 3).
