Summary
The presence of pedestrians in a driving simulator encouraged drivers to slow down. Traffic engineering designs like warning signs and lane narrowing had mixed effects on reducing driving speeds at crossings.
Area of Science:
- Traffic Safety
- Human Factors in Driving
- Transportation Engineering
Background:
- Driver behavior at pedestrian crossings is crucial for safety.
- Traffic engineering designs aim to mitigate risks and improve traffic flow.
- Understanding driver responses to pedestrian presence and engineering cues is essential.
Purpose of the Study:
- To investigate if pedestrian presence and traffic engineering designs influence driver speed at crossings.
- To evaluate the effectiveness of different traffic calming measures in reducing impact speeds.
Main Methods:
- Utilized a driving simulator with a 14-km virtual road.
- Included scenarios with base intersections, pedestrian presence, warning signs, and perceptual lane narrowing.
- Measured nine speed profile variables from 28 licensed male drivers.
Main Results:
- Pedestrian presence led to earlier deceleration and lower speeds before crossings.
- Warning signs at intersections and perceptual lane narrowing showed limited effectiveness in reducing speeds.
- Warning signs placed in advance of intersections were associated with higher impact speeds.
Conclusions:
- Pedestrian presence is a significant factor in reducing driver speed.
- The effectiveness of traffic engineering designs varies, with some potentially being counterproductive.
- Strategic placement of warning signs is critical for enhancing pedestrian safety.
