How to Use the Calculator
- Enter the number of vehicles passing a point per hour in the "Vehicles per Hour" field.
- Enter the lane capacity (maximum vehicles that can pass a point per hour per lane) in the "Lane Capacity" field.
- Enter the road length in kilometers in the "Road Length" field.
- Enter the road width in meters in the "Road Width" field.
- Click the "Calculate" button to compute the traffic load and other metrics.
- Use the "Reset" button to clear all input fields and start over.
Understanding the Results
- Number of Lanes: Calculated based on the road width and standard lane width (3.75 meters).
- Traffic Load (vehicles/km): The number of vehicles passing per kilometer of road length.
- Road Capacity (vehicles/hour): The maximum number of vehicles that can pass the road per hour.
- Traffic Density (vehicles/km): The number of vehicles per kilometer of road length.
Principles of Traffic Load Calculation
The calculator uses the following formulas:
Traffic Load (vehicles/km) = Vehicles per Hour / (Lane Capacity * Number of Lanes)
Road Capacity (vehicles/hour) = Lane Capacity * Number of Lanes
Traffic Density (vehicles/km) = Vehicles per Hour / Road Length
The number of lanes is calculated by dividing the road width by the standard lane width (3.75 meters). This is based on typical road design standards, but may vary in some cases.
