Classification: CPC G | IPC G

Claim 13:
14. The method of claim 10 and further comprising the steps of:
for a vehicle location spaced (queued) behind a stopline, determine a distance from a current location to the stopline;
apply a traffic engineering flow and queue dispersion model to each observed crossing relating it to the location where the respective vehicle was stopped and thus assumed queued;
The distance from the current location to the stopline is divided by an average vehicle length to determine the vehicle's position in the queue;
identify as a green start time a moment when the vehicle is observed to start minus the number of preceding vehicles in queue multiplied by the inverse of saturation flow rate multiplied by 3600 plus a startup loss time; and
adding this queued vehicle green start time to the other crossing data for the intersection for timing plan analysis.
