A vehicle comprises a vehicle to vehicle communication module, a cooperative adaptive cruise control module to determine the location of a traffic cataract (obstruction, restriction or lane closure for example) 200. The module coordinates with other cooperative vehicles to form a platoon 204, and move the platoon at a constant speed through the restriction. Some of the cooperative vehicles might not have a vehicle to vehicle communications module equipped. The detection of the traffic restriction may be performed by the adaptive cruise control module detecting the traffic state changing from free flow to synchronous flow state, detecting the vehicle speed or change in speed (headway), or by detecting the availability of gaps in the traffic. Vehicle speed may be adjusted to reach a target location in a target time period. The determination of the presence and location of the traffic restriction may be communicated from the detecting vehicle to other vehicles. A method of operating the vehicle is also disclosed.
