Older people may face **orientation problems** when they are not familiar with the streets, which increases their risk of accidents as pedestrians. This is due to several factors:

- **Hearing and visual difficulties**: Many older people have trouble hearing and seeing, which can hinder their ability to detect approaching vehicles or distinguish traffic light colors.

- **Complicated environment**: Ambient noise can prevent them from hearing vehicles, and poorly lit streets or obstacles like planters or poorly parked cars can complicate their orientation.

- **Inadequate infrastructure**: The lack of pedestrian crossings and high curbs can also pose a challenge for them.

These factors contribute to older people having more accidents when they are alone, especially in areas they are not familiar with.
