Safety application to notify emergency events and non-safety application to improve the transport efficiency are provided at the same time. The emergency events should be transmitted as quickly as possible and vehicle’s driving status is collected by a road-side unit periodically. In a congested road, the road-side unit cannot collect vehicle information periodically because this is transmitted only on the service channel. In this letter, we proposed channel interval adjustment scheme to improve capacity of road-side unit. Simulation results show that the proposed scheme provides the improved performance in congested traffic condition.
