Final answer:
Pedestrians should walk facing oncoming traffic when there are no sidewalks and use sidewalks and crosswalks in urban areas to ensure safety.
Step-by-step explanation:
Pedestrians are advised to walk on the side of the road facing oncoming traffic when sidewalks are not available. This is because it allows pedestrians to see the vehicles coming towards them and take evasive action if necessary.
While walking in towns and cities where sidewalks are present, pedestrians should use them to ensure their safety. Traffic signals and crosswalks are also critical, allowing pedestrians to cross roads safely without having to dodge traffic.
It is vital for pedestrians to respect traffic signals and crosswalks to minimize the risk of accidents. Pedestrian safety is a concern, particularly in areas with high traffic volumes and where many people need to cross roads to access places like campuses.
