Compliance
1.7. This Road Safety Audit has been carried out in accordance with the procedures and scope set out
in TII publication number GE-STY-01024 - Road Safety Audit.
5Audit Scope
1.8. As part of the road safety audit process, the Audit Team have examined only those issues within
the design which relate directly to road safety.
1.9. The road safety audit process is not a design check, therefore verification or compliance with
design standards or any other criteria have not formed part of the audit process.
1.10. All of the problems described in this report are considered by the Audit Team to require action in
order to improve the safety of the scheme and minimise the risk of collision occurrence.
62. Road Safety Issues Identified
2.1. Problem: Provision for Cyclists on Enniskerry Road
Location: Enniskerry Road, to North and South of junction with Glenamuck Road
Provision for cyclists is made in the proposed layout of Glenamuck Road, however it is unclear
how cyclists will be facilitated at the tie-ins to Enniskerry Road. Inadequate tie-ins between
proposed and existing infrastructure could serve to increase the risk of conflict between
pedestrians, cyclists and vehicles at these locations.
The proposed development, and those adjacent, may increase the number of cyclists at this section
of the Enniskerry Road. This could also serve to increase the risk of conflict between vehicles and
cyclists, where suitable facilities are not provided.
Recommendation
The Design Team should ensure that cycleways transition between each of the proposed sections
of carriageway in a consistent and safe manner. Consideration should be given to the provision of
cycle facilities on the section of Enniskerry Road within the proposed scheme.
2.2. Problem: Inadequate Visibility at Junction
Location: Junction 1, Enniskerry Road
Junction 1 onto Enniskerry Road is located on the inside of a horizontal curve. Visibility is blocked
for traffic exiting the junction by an existing wall and trees/vegetation. Visibility to the junction is
also obscured for traffic travelling southbound on Enniskerry Road due to these same constraints.
Poor visibility could result in side-on or rear end type collisions.
Recommendation
The Design Team should ensure that road users approaching the junction have sufficient forward
visibility and that road users exiting the junction have sufficient sightlines to approaching traffic.
2.3. Problem: Lack of Turning Provision
Location: Homezone areas MC10 and MC40
Turning heads have been provided for homezone areas MC20 and MC50 but have not been
provided for homezone areas MC10 and MC40. Lack of turning facilities could result in vehicles
reversing into/out of the home zones (particularly larger vehicles such as refuse lorries / fire
tenders). This could lead to collisions between general traffic and cyclists / pedestrians walking in
the carriageway.
Recommendation
The Design Team should include provision for vehicles to turn around safely.
2.4. Problem: Abrupt Transition to Cycle Lane
Location: Glenamuck Road
The cycle lane / track along the Glenamuck Road Westbound commences abruptly and with a
sharp transition to the ramp. The trafficked lane is shifted to the right in order to facilitate this cycle
track provision. Vehicles travelling Westbound along Glenamuck Road may fail to anticipate this
7change in lane alignment. This could cause vehicles to collide with the kerb or mount the cycle
track, which could result in collisions between vehicles and cyclists.
Recommendation
The Design Team should ensure that a smooth taper is provided approaching the cycle track and
that a consistent trafficked lane width is maintained by means of road markings.
2.5. Problem: Access Provision to Kilternan Abbey / Reservoir
Location: Golden Ball Junction
A dropped kerb is provided at the existing entrance gates to Kilternan Abbey / Kilternan Reservoir.
Drawing 5157801/HTR/DR/0102 notes that “entrance gates to former Kilternan Abbey not
impacted by scheme”, however there is a signalised pedestrian crossing proposed to be located in
front of these gates. The lack of formal access provision could result in vehicles mounting the kerb
and traversing the tactile in order to gain access to the entrance, which may increase the risk of
conflict between vehicles, cyclists and pedestrians.
Recommendation
The Design Team should ensure that access provision is maintained to these entrance gates.
2.6. Problem: Lack of Tactile Paving
Location: Pedestrian Crossing at Golden Ball Car Park Access
No tactile paving is shown to be provided at the pedestrian crossing across the access to the
Golden Ball car park. This could result in visually impaired pedestrians inadvertently stepping onto
the carriageway, which could lead to collisions with other road users.
Recommendation
The Design Team should ensure that tactile paving is provided at all pedestrian crossings.
2.7. Problem: Junction Radii
Location: Glenamuck Road to Enniskerry Road Southbound
The radius from Glenamuck Road to Enniskerry Road Southbound appears to be quite small. This
could create difficulty for long wheelbase vehicles such as double decker buses in navigating the
turn. This could result in conflict with other road users, particularly those waiting to turn right from
Enniskerry Road.
Recommendation
The Design Team should ensure that the radius provided is sufficient for a double decker bus to
complete the turn from Glenamuck Road to Enniskerry Road Southbound without conflicting with
other road users on Enniskerry Road.
82.8. Problem: Existing Bus Stop Facilities
Location: Glenamuck Road, opposite Cromlech Close
An existing bus stop is positioned at the location of the proposed cycle lane / grassed area. The
proposals do not detail the amendments to be made to this bus stop.
The lack of provision of a formal bus stop here could result in in-formal stopping of buses, which
could result in rear-end collisions by unsuspecting motorists following. Additionally, alighting bus
passengers at an informal bus stop could be struck by passing vehicles where there are insufficient
facilities.
Recommendation
The Design Team should make provision for the inclusion / relocation of this bus stop as part of
the proposed scheme.
2.9. Problem: Vertical Transitions to/from Cycle Track
Location: Glenamuck Road
The vertical transitions from cycle lane to cycle track (and vice versa) are located too close to both
the entrance to Cromlech Close, and the left turning lane on Glenamuck Road. This might increase
the risk of vehicles failing to anticipate cyclists who are transitioning from the cycle track to the
cycle lane.
Recommendation
The Design Team should ensure that the vertical transitions to and from the cycle track are
designed in accordance with the guidance outlined in the National Cycle Manual.
93. Audit Team Statement
3.1. We certify that we have examined the drawings and documents listed in Chapter 1 of this Report.
3.2. The Road Safety Audit has been carried out with the sole purpose of identifying any features of the
design which could be removed or modified in order to improve the road safety aspects of the
scheme.
3.3. The problems identified herein have been noted in the Report together with their associated
recommendations for road safety improvements. We (the Audit Team) propose that these
recommendations should be studied with a view to implementation.
3.4. No one on the Audit Team has been otherwise involved with the design of the measures audited.
