Speediness and willingness to get something done drivers#
Signs and signals which provide drivers with information that alerts them to hazards ahead.The system has the ability to see 100% of the carriageway CCTV cameras that our operators are able to move and zoom to monitor and manage congestion and incidents, where notified.Stopped Vehicle Detection (SVD) technology which can identify a stationary vehicle, typically within 20 seconds.Detection systems to monitor traffic for changes in flows.Clearly signed and orange-coloured emergency areas set back from the road and with telephones linking directly to our control rooms.Variable speed limits to help keep traffic moving, reducing frustrating stop-start traffic and making journeys quicker.We use a system of inter-related features and technology on upgraded motorways which include: In total there are 59 places to stop in an emergency, including retained sections of hard shoulder between junctions and on junction slip roads, every 1.3 miles on average. If drivers get into difficulty between junctions 3 and 8/9, they will be able to use one of 16 new emergency areas, bringing the total of emergency areas on the M4 between junctions 3 and 12 to 34. We have now increased the maximum speed on the upgraded section but we continue to make small adjustment to the technology and routinely check the system. Drivers were kept at a lower maximum speed limit while we adjusted the technology which detects stopped vehicles. You’ll have seen between junctions 3 and 8/9 all lanes of the upgraded carriageway were open and the speed limit was 60mph. This marks the lifting of the final restriction on the upgraded M4 between junctions 4 and 12.Ī section between junctions 3 and 4 in West London will remain at 60mph to help manage air quality in the area, and to manage traffic into London our upgrade of the road and calibration of the technology here is complete. The national speed limit has been restored between junctions 4 and 8/9. Upgraded motorway between junctions 3 and 8/9 now open
