Jonny Taflin calls, in a letter to the editor on the DN View, more traffic police, as a complement to the cameras in the quest for lower speeds in traffic. His text is, however, marred by several deficiencies.
He writes: ”the Usual speed in the dense flow of traffic is usually 10-20 km / h higher than what is allowed”. According to the Swedish transport administration’s latest hastighetsundersökning (2016), the average färdhastighetent on the state road network is 78,7 kilometers in the hour (demo page 4) and the average speed was 82.7 km / h (page 33). The measured speed is thus lower than allowed.
Taflin continues: ”Estimates are that the reduction of carbon dioxide emissions can be reduced by approximately 700,000 tons of carbon emissions per year if the traffic is adapted to the processing speed”. This is a ten year old estimate.
cleaner. The current figure is 310.000 tons per year, a figure that has not yet been published, but can be confirmed by the Swedish transport administration.
Taflin writes further: ”Investigations show that high speed kills, and that about 100 lives a year can be saved a year if the speed is reduced, for example, from 110 to 100 kilometres an hour”. Taflin gives no reference, but I’m pretty sure that although these are old figures from earlier in the 2000’s when it killed more than 500 people a year in traffic. Today it is about 300. Then becomes the abatement potential is lower.
Taflin from the downside of the lower väghastigheter, namely, the lower the mobility – the trips takes longer. It is also a cost that I myself lift in the Transporforum.
