From a traffic safety point of view road users should be able to ascertain at a glance which priority regimen is valid. To this end TNO Technische Menskunde was requested by CROW to investigate which characteristics are crucial to the recognition of the priority regimen at a specific location. The investigation proves, among other things, that road users mainly depend on road signs such as give-way road markings when determining priority. The red bicycle crossing is also a main characteristic for road users to determine whether cyclists do indeed have priority. The set-up and results of the investigation have been described in publication 126a.
