The father of a 21-year-old Amsterdam cyclist killed last month has started a petition calling for better traffic safety on De Ronde Hoep near Ouderkerk aan de Amstel.
Nina was out riding with her father on the morning of June 20 when she collided with a tractor on the route.
Resuscitation at the scene was unsuccessful.
The 28-year-old driver of the agricultural vehicle was arrested.
Why the route raises concern
Her father describes De Ronde Hoep as a popular but dangerous stretch of road.
In many places it is narrow and busy, with cyclists, walkers and runners sharing limited space with farm traffic and other motor vehicles.
Escape options are few, and the speed differences between users are large.
He is asking the involved governments and road managers to draw up and carry out a joint, comprehensive safety plan for the entire route.
Municipal and police response
He has also said he is considering legal steps against the municipality of Ouder-Amstel, which he regards as seriously negligent.
The municipality has called the fatal crash deeply sad and notes that drivers on the route generally keep to the 60 km/h limit.
It also states that more accidents occur there than average, yet sees no immediate reason for extra measures, a view it has shared with police.
The police say a site inspection still has to take place before any substantive comments, including on possible measures, can be made.
Small changes already under review
The local water board is already looking at whether minor adjustments are feasible.
De Ronde Hoep is a well-used scenic loop through the polder just south of Amsterdam and draws many recreational riders from the city.
The petition has gathered about 4,500 signatures so far.
No one can bring Nina back, her father writes, but authorities can still act to make the route safer for everyone who uses it.
