However, to clearly explain a safety problem or the recommendation to resolve a problem, the Audit Team may, on occasion, refer to a design standard without undertaking a technical audit. Issues 1.11. The RSA brief did not provide the following details and, as a result, the audit does not take these into account: Any departures from standards; Private and confidential Atkins Frideswide Square, Oxford Stage 2 RSA | Version 1.0 | October 2014 4 Frideswide Square, Oxford Stage 2 Road Safety Audit Lighting levels; Site clearance; Accident data; Classified traffic counts; and Vehicle speeds. 1.12.

Works are being proposed on Frideswide Square for the following objectives: To improve the sense of arrival for those entering the city via Frideswide Square, particularly from the railway station; To reflect the character of Oxford in the materials and landscaping of the space; To improve pedestrian, cyclist and bus user journey time and experience; To create a simple, uncluttered layout that is easy for all users to navigate without taking unnecessary detours; To reduce accidents; To improve actual and perceived journey times through the square; To promote sustainable transport and establish a balance between all modes of movement – pedestrian, cyclist, public transport, private vehicle; To create a stronger sense of place – promote public life within the space; Private and confidential Atkins Frideswide Square, Oxford Stage 2 RSA | Version 1.0 | October 2014 6 Frideswide Square, Oxford Stage 2 Road Safety Audit To boost regeneration of the West End; To accommodate the potential for events in the space; To create a public space which complements and enhances its context and provides a welcoming gateway to Oxford; To enable everyone to move through the space safely and efficiently; To co-ordinate the surrounding road network with Frideswide Square to protect buses from congestion and improve air quality in the city centre; and To give priority to movement by pedestrians, cyclists and public transport users. 2.5. To do this the following has been proposed: The proposed development significantly revises the existing arrangement of Frideswide Square. Traffic signals will be removed with traffic movements being managed by roundabout junctions instead; Buses will no longer be segregated from the through traffic and stands will be provided in lay-bys on the north and south sides of Frideswide Square; The lane widths are significantly reduced on the approaches to and through Frideswide Square in an effort to reduce and regulate traffic speed; The absence of traffic signals removes the formal crossings for pedestrians who are now catered for with a series of informal crossings on or close to the anticipated desire lines; and Becket Street, the northern part of which is currently a one way street that only permits access to Frideswide Square, will be made into a two way junction.
