#### Formula:

D = 0.0003 × (n × p^{2})^{(1 / 3)}
**Where,**
n = Number of Registered Vehicles
p = Population
D = Annual Road Deaths
### Example:

Calculate the annual road deaths using Smeed Law based on the number of registered vehicles of 50000 and population of 2000000.

#### Solution:

D = 0.0003 × (50000 × 2000000^{2})^{(1 / 3)}
