On a motorway what is used to reduce traffic bunching?

ماذا يستعمل على الطريق السريع لتقليل اكتضاض السيارات في نفس المكان؟

Explanation: Congestion can be reduced by keeping traffic at a constant speed. At busy times maximum speed limits are displayed on overhead gantries. These can be varied quickly depending on the amount of traffic. By keeping to a constant speed on busy sections of motorway overall journey times are normally improved.
