Live top speeds on Dutch motorways

Filed under: Automobiles by Branko Collin @ 1:52 pm

best-wel-snelThe site bestwelsnel.nl taps into the National Data Warehouse for Traffic Information (NDW) to bring you the top speeds registered on Dutch motorways.

The NDW registers speeds using over 24,000 detection loop pairs spaced 2.5 metres apart. Bestwelsnel.nl (the name means ‘quite fast’) displays three types of speeds: unconfirmed top speeds (grey), daily confirmed top speeds (green) and confirmed top speeds of all time (red, with all time meaning since 31 December 2013). A value counts as confirmed when it has been registered within the minute by two separate detection loop pairs that were no further than 5 kilometres apart.

In case you were wondering, the Netherlands does have a speed limit which varies depending on which stretch of motorway you are on, but the default (and highest limit) is 130 kilometres per hour. The values you see on bestwelsnel.nl all indicate speeding. The fine for going 39 kph over the speed limit on a motorway is 400 euro, if you go faster than that and get caught you have to appear before a judge.

This is an example of open data slowly getting more traction in the Netherlands—except in some cases it seems.

Speed cameras wrongly fine motorists for years

Filed under: Automobiles by Orangemaster @ 10:06 pm

Hundreds of motorists on Dutch motorways have been wrongly fined because of an error caused by speed cameras, according to Dutch news RTL. The government has known of this specific problem of mistaking vans, camper vans and cars with cycle racks for vehicles with trailers, such as caravans, which have a maximum speed limit of 90 km/h instead of 130 km/h on most motorways, since 2009. However, they said it didn’t affect enough people to do something about it so they just sat on it.

The software of the speed cameras will be updated after all and people will be refunded even though the government claims that the fines given in error were not that many.

It’s nice to see some effective journalism once in a while.
