Traffic Volumes ADT 2005

Abstract

Traffic still represents the crucial burden factor of the urban environment. Its numerical development is observed by regular traffic investigations. Responsible for these counts on highways, national highways as well as the remaining main road network is the ministry for urban development in Berlin. The current data refer to the year 2005 and update the values of the preceding count of 1998. Based on a high comparability of the data bases and methods you can look for further explications at the map text of the edition 1995.

The motorization level, i.e., the ratio of cars to the number of inhabitants, was also different for East and West Berlin in 1970. Thus, there were 77.5 cars per 1,000 inhabitants in East Berlin in 1970, compared to 175.4 in the western part of the city – a difference of almost 100 vehicles per 1,000 inhabitants. In 1995, partially due to reunification, the numbers are clearly closer together: In East Berlin, 1,000 inhabitants now have 302 cars at their disposal, compared to 346 in West Berlin (cf. Fig. 1). In comparison with other cities, Berlin thus still in 2005 has a favorable level: Munich, with 610 cars/1,000 inh. (2006), and Hamburg with ab out 480 car/1,000 inh. (2004), show far higher values. The average in Germany was about 500 cars/1,000 inh. in 2004.

h6. For the eastern part of the city, there is no information on the level of motorisation for the period from 1991 to 1993 due to the changeover of the number plates of all vehicles at that time. From 1996 onwards, a combined total is shown for Berlin.

The following overviews compare the development of the year dates of the important statistical parameters route-length and driving-performance according to traffic-burden classes in the period from 1993 to 2005. There is an increase of the total yearly-driving-performance by after all approximately 413 million km (= 3.8 percent of the yearly-driving-performance 2005 of total approximately 10.67 bil. km) (see table 1, 2 and 3).

Tab. 2: Traffic load (ADT), route length (km) and mileage (km/day) in the main road network in 1998/99

Tab. 3: Traffic load (ADT), route length (km) and mileage (km/day) in the main road network in 2005

In comparison of the three counting periods, it becomes apparent that an expansion of the main road network took place for the traffic investigations in 2005. Opposite to 1995, new highway sections were to be considered: BAB A 113 (new) Späthstraße – Adlershof as well as BAB A 100, the expansion of the western city ring through the tunnel “Ortsteil Britz” towards Buschkrugallee. But also some streets of the subsidiary, additional network “revalued” for the current traffic investigations of the main network.
So among other things these changes in the investigated network in 2005 affirm the increase of the low up to middle burdened network sections.
Taking into account the mentioned new highway sections, the class with the highest motor vehicle numbers (> 50,000) has been retained unchanged. So anymore the city-highway sections as well as the big arterial roads represents the main points of “stress concentration” within the city-road-network. The section in the range of the highway triangle Funkturm represents Germany’s busiest highway section with an average of about 212,000 Kfz/24 h passing the long-run metering point Halensee.

The main burden focuses still on the bigger highways and parkways. The continual replace of high-emitting cars through pollutant-reduced leads to a decreasing pollution in spite of the increasing driving-performance. However many traffic caused problems like particles from tyres, the noise burdens as well as the enormous surface demand of the recumbent and driving traffic remain as serious impairment of the urban life quality (see. map 03.11 Traffic-related Air Pollution – NO₂ and PM₁₀).
