1. What is Stopping Sight Distance?

Stopping Sight Distance (SSD) is defined as the distance provided on the road before a sharp turn, allowing a vehicle to come to a complete stop safely.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( SSD \) — Stopping Sight Distance (Meter)
• \( ISD \) — Intermediate Sight Distance (Meter)

Explanation: The formula calculates the required stopping sight distance based on the intermediate sight distance, which is the distance required by the vehicle to stop before an accident.

3. Importance of Stopping Sight Distance Calculation

Details: Accurate calculation of stopping sight distance is crucial for road safety, ensuring that drivers have sufficient distance to stop safely before encountering hazards or sharp turns.

4. Using the Calculator

Tips: Enter the intermediate sight distance in meters. The value must be valid (greater than 0).

5. Frequently Asked Questions (FAQ)

Q1: Why is stopping sight distance important?
A: It ensures that drivers have enough distance to stop safely before encountering obstacles or sharp turns, reducing the risk of accidents.

Q2: What factors affect stopping sight distance?
A: Factors include vehicle speed, road conditions, driver reaction time, and gradient of the road.

Q3: How is intermediate sight distance defined?
A: Intermediate sight distance is the distance required by a vehicle to stop before an accident, considering various factors such as speed and reaction time.

Q4: Are there limitations to this formula?
A: The formula assumes ideal conditions and may need adjustments for real-world scenarios involving different speeds, road conditions, and vehicle types.

Q5: Can this calculator be used for all road types?
A: While the formula provides a general calculation, specific road designs and conditions may require additional considerations and adjustments.
