How to calculate the Average Velocity of vehicles on a road within a time frame?

Hi,





I need to calculate the average velocity of vehicles on a road within a given time frame. In essence i need some statistics about roads within a road network( one of them is average velocity) for a tune frame.





I know road occupancy details (vehicles, individual speed etc) for each road at every time instance.





Any help would be highly appreciated.





Regards.|||This, to me, a bit more difficult.


Give me some time.|||If v(i) is velocity of ith Car and t(i)is the time it runs for then the average velocity of jth Car is


V(j)=sigmav(i)t(i)/sigma t(i) i=Car index. sigma(i)=T time frame


Now considering all the cars tpgether the Average velocity will be


V=sigmaV(j)/N N=total number of Cars in time T


Repeat the same for each Road and finally take the average.
