• cycleway:left=lane + cycleway:left:lane=exclusive
• cycleway:right=lane + cycleway:right:lane=exclusive
• cycleway:both=lane + cycleway:both:lane=exclusive
• cycleway=opposite_lane

Cat 2 — route mineure (calme explicite)

• highway=residential + maxspeed=30 (± oneway=yes)
• highway=residential + oneway=yes + oneway:bicycle=no (DSC zone 30)
• highway=living_street
• highway=unclassified + maxspeed≤30
• highway=service + access=destination (même avec DSC ou bicycle=yes)

Cat 2- — fond résidentiel (contexte de carte)

Cat 3 — partagé piéton (vélo ambigu)

• highway=path|footway|pedestrian (seul)
• area=yes + highway=pedestrian
• highway=path + segregated=yes

• cycleway:both=lane + cycleway:both:lane=advisory
• cycleway=opposite (DSC sans aménagement)
• cyclestreet=yes + highway=residential + maxspeed=20
• bicycle=yes + highway=service + oneway=yes + oneway:bicycle=no

Cat 5 — praticable mais pénible

• bicycle=dismount
• highway=steps
• highway=path|footway|pedestrian + bicycle=no

Cat 6 — overlay balisage (surcouche au rendu)

• route=bicycle (relation)
• network=icn|ncn|rcn|lcn (relation)

Règles de priorité (plus spécifique gagne)

1. path|footway|pedestrian + bicycle=no → Cat 5 (overrides Cat 3)
2. path + bicycle=designated + foot=designated → Cat 3++ (overrides Cat 1)
3. cyclestreet + residential + maxspeed=20 → Cat 4 (overrides Cat 1)
4. residential + cycleway=track ou bicycle=designated → Cat 1 (infra dédiée gagne sur Cat 2-)
5. residential + maxspeed=30 + cycleway=lane (sans exclusive) → Cat 4 (lane gagne sur calme)
6. service + access=destination + DSC → Cat 2 (calme gagne sur DSC)

Exclu / mis de côté

• cycleway:right=shared_lane (chevrons casse-gueule)
• cycleway=opposite_share_busway (rare)
• cycleway=opposite_track (deprecated)
• amenity=bicycle_parking et autres amenities vélo (à traiter plus tard)
• bicycle=no seul sur autres types de voies (Cat 0 « interdit » — non décidée)
• proposed:route=bicycle
