The Smeed's law is a law which states about the empirical relationship between the traffic deaths and traffic population. As per the Law, an increase in motor vehicle registrations leads to an increase in fatalities per capita, but a decrease in fatalities per vehicle. This page contains the Smeed's law formula for you to calculate the annual road deaths. You need the input values of the number of registered vehicles and the population to perform calculation using this Smeed's law formula.

Where,

n = Number of Registered Vehicles

p = Population

D = Annual Road Deaths

Smeed's hypothesis has been argued by several authors, who claims that the occurrence of death per person has reduced. Make a note of this Smeed's Law formula to predict the fatalities based on the congestion.
