Which component is essential for managing pedestrian safety on streets?

The correct choice emphasizes the importance of continuous handrails in ensuring pedestrian safety on streets. Continuous handrails provide support and guidance for pedestrians, especially in areas where many people may be walking, such as near public transportation or at intersections. They enhance safety by preventing falls, particularly for individuals with mobility challenges or those who may be unsteady on their feet. The presence of handrails can also help channel pedestrian movement, clearly delineating the safe areas for walking and making it easier for pedestrians to navigate areas that might otherwise be risky or chaotic.

While options such as increased traffic signals and wider vehicle lanes may contribute to overall traffic management, they do not directly address the specific needs of pedestrians in the same way that continuous handrails do. The reduction of sidewalks is counterproductive to pedestrian safety, as sidewalks are essential for providing a dedicated space for walking, away from vehicle traffic. Therefore, the focus on continuous handrails effectively highlights a proactive approach to enhancing pedestrian safety on streets.
