Consider highlighting:
- Places where speeding is a problem.
- Places where it is difficult to safely cross.
- Places where lighting is insufficient.
- Places where street design causes conflict between cars and pedestrians (like slip lanes).
- Places where pedestrian refuges would aid crossing.
- Bus stops that lack shelters.
- Places where sidewalks are insufficient.
- Places where you would like to bike but currently feel unsafe without protected infrastructure.
