3 The appropriately sized chevrons The size of the yellow boarder on the (including appropriate yellow backing) chevron signs confirms to TSRGD 1994. should be provided on the bend to The chevron sign is still functional and benefit both directions of travel. Clear therefore no requirement to make visibility of the signs should be provided. changes until the chevron needs to be replaced: Due to the amount of kerb strikes, this An additional chevron sign (TSRGD bend may benefit from additional | Diagram

Advisory Maximum Speed Sign We have considered your recommendation of an 'advisory maximum speed sign' for the eastbound direction of travel: The Council is required to follow the Department for Transport's traffic sign regulations which include the following maximum speed sign (diag: 513.2): Max speed 30 The regulations for this sign state: "Maximum Speed Advised" is prescribed for use only in combination with the "Loose chippings" sign (Diag: 7009) or the bend warning signs (Diag: 512, 512.1, 512.2 or 513) The sign should be used sparingly, as in general it should be for drivers to judge what speed to adopt It is not easy to determine a standard safe speed to negotiate a bend; factors which influence this include radius of curvature, camberlsuper elevation, road surface condition and type of vehicle. The sign may be used where the road layout is such that a driver might be misled, e.g. at an exit from high-speed road where significant slowing is required before negotiating a sharp bend. It may also be used on high-speed roads where the horizontal design radius cannot be achieved, but a mandatory speed limit is not imposed: It must not be used with mandatory speed limit signs, nor in place of repeater signs: The above criteria for "Maximum Speed Advised" sign are not met at this location. However; the traffic sign regulations do include the following "Reduce Speed Now" sign as follows (diag: 511):
REDUCE SPEED NOW The regulations for this sign state: "An alternative to diagram 513.2 where drivers tend to enter a bend at excessive speed, is to plate the bend warning sign with diagram 511 "Reduce Speed Now" signs: The above criteria is met for this sign and therefore we will install a "Reduce Speed Now" sign plate below the existing eastbound combined 'bend to the rightlhorse warning' sign arrangement by the end of May 2017 . hope the above actions reassure you that We have addressed all the recommendations made.
