2014. The salient proposals in the Hartley Bends locality were as follows: INVESTORS An executive agency of the IMPFOPLF Denartment for Transnort Flax from May they they
Interactive vehicle activated signs (VAS) to be installed on the north and southbound approaches to Hartley Bends: These signs visually are activated by high speed and advise drivers to slow down and of the geometric hazards ahead; Introduction of high friction surface (HFS) material that will visually highlight the road's geometry and provide improved road holding for vehicles; Additional hatching to provide separation between opposing traffic streams_ (NB this was later deleted from the proposal after evidence emerged that the area to be hatched was consistently overrun and could present danger to powered two wheelers (PTW); The provision of yellow backing boards to augment the existing 50 mph signs (NB following discussions with the local Area of Outstanding Natural Beauty (AONB) Board these were removed in favour of the use of larger roundels to achieve the same improvement with reduced environmental impact): As previously stated, these works were programmed for early 2014 and therefore after November 2013_ However , following 2 November, we took the additional precaution of providing temporary advisory 30 mph signing while we looked into accelerating future road surface renewal works, over and above the planned safety scheme. am pleased to say that the road resurfacing and the majority of the safety scheme were completed in this year. The exception is the VAS signs that have been installed but not switched on, primarily due to construction issues but also to allow us to collect 'before' and after' speed information to determine their effectiveness and inform future decisions In section 5(3) of your report you make reference to 'rumble strips'. believe you are referring to yellow bar markings as used on the approaches to roundabouts These are not considered suitable for use on single carriageway roads as need to be laid verge to verge in order for their extremities not to cause hazard to oncoming vehicles and if used on bends such as the A46 can reduce traction for vehicles_ There are also adverse environmental effects such as increased noise_ However, high friction surfacing (HFS) can, and has_ laid in strips primarily for increased longevity of the material and improved vehicle traction: This also results in a similar rumble impact for drivers that believe you envisaged_ trust you consider the above satisfies points 3 and 4 of section 5 of your report: In reviewing the 2011 report still consider that the now implemented local measures to highlight the nature of the road are logical and proactive steps, which may positively affect speeds without the need: for revised posted limit; As regards recommendation 2 f Section 5 we proposed the following future actions: peer review by one of our other service providers not connected with this locality or the original piece of work. This is expected to be completed by the end of July 2014. May they been your
2 The gathering of data to ascertain the effectiveness of the now implemented safety scheme together with reasonable period of accident monitoring to gauge impact; and if required, further intervention development: In this case one year would seem appropriate. Additionally we have been in contact with Avon and Somerset Police regarding their support of the imposition of potential reduction in speed in this locality should monitoring and review of the new works indicate that it should be re-considered_ The Police have indicated that they would not oppose such proposal but confirm that it would not be routinely enforced. The Agency takes its responsibilities seriously in terms of road safety and the competing needs and requirements of our customers. trust that on this occasion you consider the tangible improvements we have already made since November, together with the commitment to continue to assess the situation, are in accordance with your recommendations
