ATM
|
On the M42 between junctions 3a and 7, the Highways Agency has implemented a new pilot scheme called Active Traffic Management (ATM). Controlled from the West Midlands RCC, Peek has provided a separate HATMS system for this pilot and has developed new software to provide Operators with the facility to use the hard shoulder as a running lane during periods of high congestion. Key to the development of this new software was its safe operation under all circumstances. As such, the software was based upon similar safety related software previously developed by Peek that provides a Tidal Flow facility on the A38M where the number of running lanes in or out of Birmingham can be varied between two and four. |

The ATM pilot scheme includes a denser than normal MIDAS provision with in-road loop detectors every 100m rather than the more usual 500m spacing. Incidents or high levels of traffic congestion detected by MIDAS will cause HATMS to implement mandatory speed settings on overhead Advanced Matrix Indicators in a scheme known as 'Controlled Motorways'. Enforcement of these mandatory setting will be made using a new Peek supplied Digital Enforcement Camera System (HADECS) which will encrypt evidence before transmitting this over secure links to a central processing facility.
