A12 and a120 route management strategy

9.3.24 Strategy Element

A12 and A120 Route Management Strategy

9.3.24 Strategy Element
Action: Install Variable Message Signs (VMS)
Priority: Medium Ref: 12A
Initiation: There are no facilities for providing driverswith real-time traffic information on the A12 or A120. This can be frustratingfor drivers as alternative routes once on the A12 or A120 are limited whenincidents occur.
Action description: Variable message signs at each end of the A12will be managed through the traffic control centres. When linked to other VMSon connecting routes, traffic can be diverted before reaching the A12 or A120.

Consultations have revealed that road users would like much more informationon conditions along a route even if they are held up in a jam and there is noalternative route.

Seven additional signs along the A12 and A120 would provide comprehensive coverage.
Objective(s) met: Economy objectives OC2, 3 and 4 will be the primebeneficiaries of the VMS system
Benefits: Vehicles being diverted before joining any queuescaused by incidents will minimise congestion and air pollution.
Timescale: VMS would be most effective if operated by a trafficcontrol centre along with active traffic management systems (see 7A), which arenot yet in place but are being proposed. Therefore, VMS is not practical untilabout year 5 of the programme.
