How to Calculate Traffic Growth Rate for DPWH Roads
In order to determine the growth rate of traffic on DPWH-managed roadways, it is essential to analyze historical traffic data over a specific period. This metric provides valuable insights for infrastructure planning and improvements. The process involves comparing traffic volumes from two different periods, typically using Annual Average Daily Traffic (AADT) as a measure.
The general formula for calculating the traffic growth rate is straightforward. However, it requires accurate traffic data from reliable sources, such as traffic count stations or reports. Here is a step-by-step guide to calculating the growth rate:
Steps to Calculate Traffic Growth Rate
- Obtain traffic volume data from the previous and current year. Data is usually recorded annually as AADT.
- Subtract the previous year's volume from the current year's volume to find the difference in traffic count.
- Divide the difference by the previous year's traffic count to get the relative growth rate.
- Multiply by 100 to express the growth rate as a percentage.
Formula for Traffic Growth Rate
| Growth Rate (%) | =(Current Year AADT - Previous Year AADT) / Previous Year AADT * 100 |
|---|
Important: Ensure that traffic volumes are measured under similar conditions, considering factors like seasonal variations or special events that may skew the data.
By following this method, transportation planners can identify trends in traffic flow, helping to forecast future demands and make informed decisions on road maintenance or expansion projects.
