Insights
Child pedestrian crashes are common, often occurring in good weather and daylight. Prevention efforts should address children
Area of Science:
- Pediatric injury prevention
- Traffic safety research
- Urban public health
Background:
- Motor vehicle-pedestrian crashes are a leading cause of serious injury in children.
- Previous research focused on child and traffic factors.
- The role of driving conditions in these crashes requires examination.
Purpose of the Study:
- To investigate the influence of driving conditions on pediatric pedestrian crashes.
- To identify specific environmental and temporal factors associated with these incidents.
Main Methods:
- Analysis of 3823 pediatric pedestrian crashes in Philadelphia from 1994-1999.
- Data abstracted from police reports, including pedestrian and environmental factors.
- Inclusion criteria: children under 18 years involved in pedestrian crashes.
Main Results:
- Crashes predominantly occurred in dry conditions (90%), good weather (90%), and daylight/under streetlights (92%).
- Peak crash times included Friday afternoons (3:00-6:00 PM) and spring months (May).
- Children were often crossing mid-block (87.9%) or behind vehicles (38.8%); 32.3% sustained injuries exceeding minor severity.
Conclusions:
- Optimal driving conditions (good visibility, dry roads) coincide with increased child pedestrian crash risk.
- Factors include high child exposure during favorable conditions and unsafe crossing behaviors.
- Prevention strategies must highlight the dual risk of optimal conditions for both driving and child play.
Objectives:
Motor vehicle-pedestrian crashes are one of the leading causes of serious injury in children. Prior studies have focused on child and traffic factors contributing to these crashes. The objective of the current study was to examine the role of driving conditions on the occurrence of motor vehicle crashes involving child pedestrians.
Methods:
Detailed information was abstracted for the period January 1994 to December 1999 from the Philadelphia Police Department accident reports for all pediatric (age <18 years) pedestrian crashes in a single, urban county. Data included pedestrian age, road and weather conditions, illumination, pedestrian location, and intent, time of day, and date of incident.
Results:
For the 6-year period of review, there were 3823 children under 18 years of age struck by motor vehicles (range 518 to 726 crashes per year), representing an average of 1.7 per day and a rate of 181 crashes per 100,000 children per year. The mean age was 7.9 years +/- 3.9 (range 1 to 17 years). Crashes occurred when the street was dry (>90%), with no adverse weather conditions (>90%), and during daylight hours or under streetlights (>92%). The most frequent day of the week was Friday (18.1%). The most common time of day was 3:00 to 6:00 PM (38.7%). The spring months (39.1%) predominated, with May (14.0%) being the most common month and January the least. When the circumstances were known, children were struck crossing in midblock 87.9% of cases and crossing behind a vehicle 38.8% of the time; only 4.8% were struck while playing in the street. Injuries as reported by the police exceeded minor in 32.3% with an overall fatality rate of 0.7%.
Conclusions:
Urban pediatric pedestrian crashes are common and occur most frequently during optimal driving conditions (good lighting, a dry road, and good weather). The data also suggest that pedestrian crashes are related to the saturation of the streets with children (optimal play conditions) compounded by poor street-crossing technique. Prevention efforts should reinforce the fact that optimal driving conditions are also likely to represent optimal conditions for child play and may increase the risk for pediatric pedestrian injuries through increased exposure.
