HIGHWAYS AGENCY RELATIONSHIP BETWEEN TACTICAUSTRATEGIC SIGNS AND SIGNALS There are two categories of usage for signs and signals , with these being tactical or strategic. In simple terms tactical signs and signals shall be set in an area which is a maximum of 5km or 2 junctions from either the scene of an incident (or other event which drivers need to be informed of), or from the rear of any queues which have formed as a result of the incident. Tactical VSS shall always focus on providing queue protection legends which warn drivers of an incident that is immediately ahead . Other incidents which have occurred further along the motorway shall be signed for using strategic legends. Once drivers have passed the original incident location then new tactical signs and signals relating to other incidents shall be set. This is to ensure that tactical legends which relate to different incidents are not mixed, as this can provide confusing and inconsistent information to drivers. With the exception of tactical diversion legends, all legends which advise drivers to use an alternative route due to an incident/event are strategic. Strategic VMS (signals shall not be used for strategic use) shall only be set outside of the tactical signing area and not within the tactical signing area except in the below circumstances where there is a requirement to display a strategic legend in the tactical incident area; In circumstances where drivers who have joined the motorway within the tactical signing area need to be made aware of the strategic information as to do so any further along their journey would not allow them to act on the information provided. A travel time or delay time message - see section 7.4 A security legend- see section 7.15 and Annex C.11 All other strategic legends such as campaigns , notification of future road works etc shall be removed from a tactical incident signing area until the incident has ended and the tactical signs removed. Specific uses of tactical and strategic VSS are detailed in sections 6 and 7.
