The approaches to Little Casterton from the west is national speed limit and the approach from the east is 40mph. The 40mph limit starts at the junction with the A6121 and finishes at the far eastern end of Little Casterton. The village is 30mph for its entire length. The road through Little Casterton can be used by vehicles to link the A6121 with the B1081. Vehicles travelling from Ryhall may use this road to access the B1081 to link onto the A1. 4 | P a g e Vehicles entering Little Casterton from the west are travelling from either Stamford along Little Casterton Road, or Great Casterton along Tolethorpe. Both of these roads are classified as C class roads. Both are rural lanes without any footpaths. The western approach has recently been upgraded to include new road markings, a chicane, and signs and buff coloured High friction surfacing, as illustrated below. The average speed at the western end of the village before the chicane was installed was 35mph (2015); following the installation of the chicane the average speed has reduced to 21mph (2017). (See Section 3 Speed Survey for further information). 5 | P a g e Vehicles entering Little Casterton from the east are travelling from the A6121, Ryhall, along Tolethorpe. There is only one road access with Tolethorpe between the A6121 and Little Casterton, Salters Lane. This road is used to access Tolethorpe Hall and links to Ryhall Road. The eastern approach to Little Casterton was upgraded at the same time as the western approach, to include a new village name plate, white lining and high friction surfacing. The signs have been placed approximately 100m east of the first house when entering Little Casterton from Ryhall. The village name plate includes the 30mph roundel and is on yellow backing. The 30mph roundel on the opposite side of the road does not have any backing. 6 | P a g e As shown in the image above, the Little Casterton sign is obstructed by vegetation. The Traffic Signs Manual Chapter 4 1states it is essential that drivers have an unobstructed view of traffic signs. The required visibility of a traffic sign will be depended upon the approaching speed. This traffic sign is for vehicles entering the 30mph limit from a 40mph limit, therefore drivers should have a clear visibility of the sign for 75m. It is important that sight lines are properly maintained so that the intended warning is not compromised. At this location the village name plate is not having the desired effect as it is obstructed by foliage. The Traffic Signs Manual Chapter 3 states “where a speed limit other than the national limit is in force, direction 11 (2) requires that repeater signs are provided at regular intervals along the road. However, this does not apply to a 30mph speed limit on a road with a system of carriageway lighting; in built-up areas it would be impracticable to place 30mph repeater signs on every road. To do so in some cases by not others would result in inconsistency and driver uncertainty. This is therefore prohibited by direction 11(4). Section 82 of the Road Traffic Regulation Act 1984 defines a road that has a system of street lighting (carriageway lighting in Scotland) as being a “restricted road” (see para 14.2). Section 81 specifies that the speed limit along such a road shall always be 30 mph unless an order has been made to impose another limit and remove the restricted road status. The presence of carriageway lighting therefore means that a road automatically has a speed limit of 30 mph with the lamps taking the place of repeater signs.”2 The speed limit through Little Casterton is 30mph. There is a series of street lights along Main Street, and therefore to comply with the Traffic Signs Manual Chapter 3, no repeater roundels have been installed through the village. 1 Traffic Signs Manual Chapter 4 - https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/226765/traffic- signs-manual-chapter-04.pdf 2 Traffic Signs Manual Chapter 3 - https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/223943/traffic- signs-manual-chapter-03.pdf 7 | P a g e 2 Accident Data There have been 2 recorded accidents through Little Casterton between 1/1/2008 and 30/9/2018. Accident 200802291 – V1 travelling north east towards Little Casterton at high speed collides with V2 turning right from Little Casterton Road. Both drivers were slightly injured Accident 201401043 – V1 reversing travelling south east from the Chantry Enters Main Road in front of V2 (motorcycle) travelling south west through Little Casterton. V2 swerves to avoid V1 and collides rear V2 parked ahead in carriageway. The motorcyclist was seriously injured. Neither of these accidents were in relation to the speed of vehicles through the village. 8 | P a g e 3 Speed Survey Speed survey western end of village prior to chicane being installed.

A speed survey was carried out at the far east of the village just inside the 30mph speed limit. This survey was carried out between 19/4/2017 and 26/4/2017. The approaching data is traffic entering the village and the receding data is traffic leaving the village towards Ryhall. 10 | P a g e Average Speed 34mph Bidirectional Approaching Receding 19/04/2017 36 35 36 20/04/2017 35 33 36 21/04/2017 35 34 36 22/04/2017 34 34 34 23/04/2017 35 35 36 24/04/2017 34 33 36 25/04/2017 33 32 33 26/04/2017 33 31 35 85th percentile speed 40mph Bidirectional Approaching Receding 19/04/2017 41 40 42 20/04/2017 40 40 41 21/04/2017 40 40 41 22/04/2017 40 39 40 23/04/2017 41 40 42 24/04/2017 40 40 41 25/04/2017 39 38 40 26/04/2017 40 38 41 This speed survey has highlighted that vehicles entering and existing the village are going in excess of 30mph. The approach to the village is slightly down hill and straight which could cause vehicle speeds to be in excess of 40mph as they approach the 30mph limit.
