the conditional zones filter what is processed by the one or more smart traffic cameras;
automatically determining whether the conditional zones are to be validated;
upon automatically determining that the conditional zones are to be validated, validating the conditional zones manually based on human feedback or automatically to create validated zones; and
applying the validated zones to the one or more smart traffic cameras at the intersection, wherein switching from the conditional zones to the validated zones changes the portion that are processed from the one or more smart traffic cameras.
2. The method of claim 1 , wherein creating the conditional zones at the intersection comprises:
tracking objects detected at the intersection including points at the intersection at which different objects stop; and
creating the conditional zones based on movement of the objects and the points.

6. The method of claim 4 , wherein upon determining that the conditional zones are to be validated automatically, validating the conditional zones comprises:
querying a zone creation database to retrieve identified zones and parameters corresponding to intersections of a same type as the intersection; and
updating the conditional zones and the corresponding parameters based on the identified zones and the parameters retrieved from the zone creation database, updated zones and corresponding parameters constituting the validated zones.
7. The method of claim 6 , wherein the zone creation database stores, for each different type of intersection, corresponding zones and parameters, the corresponding zones and the parameters being constantly updated using a machine-learning algorithm operating on data collected on movement of objects at the intersection.

memory having computer-readable instructions stored therein; and
one or more processors configured to execute the computer-readable instructions to:
receive traffic data at an intersection from one or more smart traffic cameras installed at the intersection;

the conditional zones filter what is processed by the one or more smart traffic cameras;
automatically determine whether the conditional zones are to be validated;
