Carl Johan von Seth: So many chipspåsar costs a week's SL-chaos

Slip, power outages, staff shortages and vagnbrist. And then continued the misery: Ställverksfel, signal errors, växelfel.

last week, the locals had a massive infarction of the city's large kollektivtrafiksapparat. First, it took a stop in the commuter trains and bus lines. In the aftermath of the snövädret have regional trains, metros and tramways also been delayed. Hardly any part of the network has been spared from the congestion and interruption.

a week of SL-chaos?

the Consulting firm IHS Global Insight made 2015 a simple calculation which gave an indication of how expensive snow storms in the USA's different states will be. This took particularly into account the disruption and the effects of reduced production, lost income, reduced retail sales and lower tax revenues.

The calculation showed that the socio-economic the loss of a really braksnöoväder in the state of Minnesota was approximately 160 million dollars per day.

Now differ Stockholm county in several respects from Minnesota. But if we only adjust for the difference in the population corresponds to the sum of 720 million dollars.

There will be 22 million chipspåsar per day if we use the same exchange rate between the sek and chipspåsar as finanslandstingsrådet Torbjörn Rosdahl (M) once did when he spoke about the increases in the prices of the SL monthly. But here we are talking about a extremscenario.

the Swedish transport administration's figures. The authority has a large model that is used to make socio-economic calculations of various trafikprojekt.

Here you will find a kind of distributed unit costs for delays and congestion. A one-hour delay in regional and local transport is estimated to give a loss of between 199 and 259 sek per arbetspendlare.

in Addition, congestion is a komfortkostnad. If the capacity utilisation of public transport is 200% and everyone is forced to stand to förseningskostnaden according to the Swedish transport administration is multiplied by the 2,93.

the locals have become in the week, unfortunately, there is no one who has figured it out. Therefore, we must rely on the testimony of the metro struldrabbade green line that says that the delays could be at least an hour on both Tuesday morning and on Thursday.

What we also know is that, during a regular morgonrusning step of about 125.000 passengers on the green line. If all was delayed by an hour, and at the same time we expect in trängselmultiplikatorn, we are up in a cost of around 73 million per morning.

And say, for the sake of simplicity, to just as many people were delayed in the other parts of the Stockholm public transportation at least two of the days the past week.

Then the bill for one week of SL-chaos: 9 million chipspåsar.

Eat them with dip, the Stockholm county council.
