A method for controlling packet transmission at a PTN access node for an ITS communication network and an apparatus for the same are disclosed. A packet transmission control method according to an embodiment of the present invention may include: a step of classifying into a plurality of service classes including control traffic and video traffic based on the header and service identifier of a received frame; a step of receiving traffic event metadata including signal cycles, conflicting traffic events, and priority signal events from a control policy server; a step of generating scheduling parameters including time slot allocation parameters for a control traffic queue and weight adjustment parameters for a video traffic queue based on the metadata; a step of calculating a microburst indicator based on frame inflow characteristics in a short-time observation window, and determining the output order by performing queue management and scheduling control for a queue by service class according to the scheduling parameters and the microburst indicator; a step of transmitting by applying a predetermined transmission encapsulation according to a service identifier; and a step of maintaining an independent protection domain for each service and performing linear or ring protection switching only for the corresponding service when a threshold is exceeded based on an OAM performance indicator for each service.
