How do children perceive and respond to crosswalks and surrounding traffic conditions?

Children are particularly vulnerable when crossing streets. However, limited evidence exists on how they perceive crosswalk design, visibility obstructions, and other environmental conditions—and how those perceptions influence their behavior.

This study used immersive virtual reality experiments to examine how an unsignalized T-junction in a school zone affected participants’ perceived safety, crossing behavior, and visual attention.

A total of 178 participants took part in the study, including younger children aged 8–10, older children aged 11–12, and their parents.

Research Method

Participants crossed a virtual school-zone street under a range of environmental conditions. Their movements, viewing directions, attentive behaviors, and perceived safety were recorded and analyzed.

A key methodological contribution was the use of counterfactual analyses based on Reproduced Virtual Experiment Data, or CARVED, techniques.

Using participants’ recorded positions, movements, and viewing directions, we replayed each crossing and reconstructed the scenes they had actually observed. We then compared those scenes with counterfactual versions of the same crossing under different street conditions, such as the presence of parked vehicles.

This approach allowed us to examine how changes in the street environment affected children’s visibility and whether they adapted their behavior in response.

Key Findings

• Younger children showed fewer attentive behaviors

Children, particularly those aged 8–10, displayed fewer attentive behaviors on sidewalks and roadways than parents, despite having greater physical and cognitive limitations.

They were also more likely to follow informal crossing paths rather than remain within the intended crossing area.

• Responses to hazardous conditions varied by developmental stage

Older children and parents generally became more cautious when they encountered hazardous street conditions.

Younger children, however, made only limited behavioral adjustments. This suggests that recognizing a hazardous condition does not automatically lead younger children to adopt safer crossing strategies.

• Parked vehicles obstructed visibility, but younger children did not compensate

Parents perceived streets with parked vehicles as less safe. They also demonstrated more attentive and preventive behaviors when entering the roadway.

In contrast, younger children often failed to recognize the danger created by the obstruction. Even when a parked vehicle blocked their line of sight, they rarely moved to a more visible position or increased their visual checking behavior.

• Decorative crosswalks encouraged diagonal and dispersed crossings

Traditional crosswalks provided clearer directional guidance and encouraged participants to cross the street using shorter, more orthogonal paths.

Decorative crosswalk patterns, although visually attractive, often encouraged diagonal and dispersed crossing trajectories. They were also associated with a higher proportion of informal or noncompliant crossings.

• Posted speed limits had no significant behavioral effect

The speed-limit conditions used in the experiment did not have a statistically significant effect on perceived safety or crossing behavior.

Implications for Safer Street Design

A street should not be considered safe simply because it appears safe to an adult.

Street and crosswalk designs should be evaluated from a child’s eye level, with attention to what children can actually see, what may be hidden from view, and how they behave when they encounter risk.

The findings highlight several priorities for safer school-zone design:

• Provide clear visual guidance through conventional crosswalk markings.

• Prevent illegal parking near school-zone crossings.

• Evaluate sightlines from a child’s eye level.

• Use behavioral and visual-attention data when assessing pedestrian safety.

• Account for differences in perception and decision-making across developmental stages.

Safer streets require more than visually appealing design. They require evidence about how children actually perceive, interpret, and navigate the built environment.
