Economic analyzes on the passage from 90 km / h to 80 km / h in France ...

as a taxi driver on sometimes long distances at night (for example this night a Tours Nantes by motorway) ... at 3 € per km ... on motorway dry loss: 60 € per hour ... with the limit to 80 we had lost 7km an hour so 21 € an hour (the hourly wages of the driver all inclusive) ... There ... 60 € ...

Bin bill by the hour

The regulations are such that you have the obligation to invoice at the "taximeter" device controlled by the state and price imposed by the prefectures ... So price with empty return at night or on Sunday is 3 € per km ( knowing that you do not have the right to charge someone after having made your deposit because you are not in your parking municipality), or, if you drive at less than 15km / h (slow walking or waiting) the taximeter switches to an hourly rate of 23 € 50 per hour ....

Source? Methodology ?

It seems to me that this simulator, very well done, does not give the same conclusion ... I need to replay it a little with ...

It is however logical, the safety distance increases to the square of the speed. By decreasing the speed, the number of vehicles traveling at the same time on the same portion of the road is increased, in a greater proportion than the reduction in speed ...

Yes this is valid for peripherals when there are a lot of vehicles and lane changes (this simulator deals with these cases precisely) ... but when it is "pure" highway with "normal" traffic I doubt that the optimum speed is 60 km / h!

Or then I didn't understand anything!

[dede2002]

But yes you understood correctly. I forgot to add "on a saturated road", and the safety distance does not increase exactly to the square of the speed, it must be weighted by the reaction time, which is variable depending on the condition of the driver. . that complicates the calculation a bit
