ENGINEERING – TRANPORTATION ENGINEERING CALCULATOR
Pedestrian Crossing Time
A precise tool.
What is the Pedestrian Crossing Time & How does it work?
Pedestrian crossing time is the duration required for an individual to traverse a marked crosswalk. It depends primarily on the width of the crossing and the walking speed of the pedestrian.
Transportation guidelines use this time to design signal phases, ensuring that the allotted walk interval is long enough for the slowest expected users while maintaining efficient traffic flow.
The calculation is straightforward: divide the crossing width by the pedestrian’s average walking speed. This yields a time value that can be rounded to the nearest tenth of a second for practical use.
t = frac{W}{v}
t = crossing time (seconds)

Frequently Asked Questions
How do I calculate pedestrian crossing time?
Divide the crossing width by the pedestrian's average walking speed to get the crossing time.
What factors affect pedestrian crossing time?
Pedestrian crossing time is primarily affected by the width of the crossing and the walking speed of the pedestrian.
Why is pedestrian crossing time important in traffic engineering?
It ensures that the walk interval is long enough for all pedestrians, including slower users, while maintaining efficient traffic flow.
What is a typical average walking speed for pedestrians?
A typical average walking speed for pedestrians is around 1.4 meters per second or about 5 kilometers per hour.
How does crossing width impact pedestrian crossing time?
The wider the crosswalk, the longer it takes to cross, assuming a constant walking speed.
Can I use this calculator for both metric and imperial units?
Yes, you can input values in either metric or imperial units, and the calculator will provide the crossing time accordingly.
What should I consider when designing signal phases based on pedestrian crossing time?
Consider factors like the width of the crosswalk, average walking speed, and the presence of any obstacles or distractions that might affect pedestrians' speed.
