AASHTO/ITE Pedestrian Clearance Time Validator calculator computes Pedestrian Clearance Time in s using the defined engineering formula and the input values provided. Pedestrian Clearance Time is expressed in s. No universal acceptance threshold is defined by this calculator.
Worked Example
Verified calculation
Given:
- Crosswalk Width = 12
- Design Pedestrian Walking Speed = 1.2
- Pedestrian Start-Up Time = 1
Expected Result:
- Pedestrian Clearance Time = 11
Engineering Interpretation:
Under the given input conditions, the calculated result is: Pedestrian Clearance Time = 11 s.
The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Frequently Asked Questions
What does this calculator calculate?
The AASHTO/ITE Pedestrian Clearance Time Validator calculator estimates Pedestrian Clearance Time based on the input parameters you provide
Why is crosswalk width important in this calculation?
crosswalk width is directly proportional to pedestrian clearance time. When you enter crosswalk width in m, the calculator uses it in the engineering formula to compute the output
How should I interpret the result pedestrian clearance time?
The calculator outputs pedestrian clearance time in s. The result is computed directly from the input values using the defined engineering formula
What units should I use for the inputs?
Enter each value in the units shown next to the input field: Crosswalk Width (m), Design Pedestrian Walking Speed (m/s), Pedestrian Start-Up Time (s). Make sure all inputs use the specified units for consistent results
What assumptions does this calculator use?
This calculator uses automatically validated engineering formulas. Results are approximate and should be validated against site-specific conditions, applicable codes, and professional engineering judgment
