Anzahl an Autos auf der Autobahn Strecke München - Nürnberg (pro Tag)

Brinja asked on Jun 25, 2018 - 1 answer

Ich würde wie folgt vorgehen:

Schritt I: Annahme: 170 km (170 000 m) * 6 Spuren = Gesamtlänge von ca. 1 Mio Meter

Schritt II: Durchschnittliche Auslastung d. Strecke: 40 % ("Rush Hour": 4 Std./Tag --> 80%, Mittel: 10 Std./ Tag --> 50%, Nachts/ Abends: 10 Std. / Tag --> 10%)

Schritt III: Autolänge ca. 3 Meter --> 1 Mio. Meter* 0,4 / 3 Meter = ca. 133.000 Autos

Schritt IV: 133.000* 24 (Angabe auf Tagesbasis) = 3.2 Mio Autos

Hi Brinja,

Ansatz passt aus meiner Sicht, nur

1. Eine implizite Annahme welche du hier triffst ist dass jedes der 133k Autos die durchschnittlich gleichzeitig auf der Autobahn sind wiederum im Durchschnitt eine Stunde zwischen München und Nürnberg unterwegs ist (siehe dein letzter Rechenschritt)

2. Die Auslastungswerte scheinen extrem hoch - 80% hiesse ja z.B. dass auf einer Länge von 100 Metern 80 Meter ständig von Autos "bedeckt" sind. Unter Berücksichtigung von Sicherheitsabständen eher nicht realistisch (es sei denn du unterstellst einen durchgehenden quasi stillstehenden Stau zwischen München un Nürnberg ;)).

Aber genereller Ansatz wie gesagt absolut okay!

(edited)

ok top, ja mir ging es hauptsächlich darum ob die Zahlen mit 24 multipliziert werden müssen (da 24 h), da war ich mir irgendwie unsicher. — Brinja on Jun 26, 2018 (edited)
