— 60 metre cycle lane to run in middle of four traffic lanes.
Planned traffic management changes mainly focused on the north and south quays in Dublin also includes making the junction at Christ Church Cathedral more complex with sub-standard cycle lanes.
The design goes against principals and key details in the National Cycle Manual and the Manual for Urban Roads and Streets, including the principal that left slip turns should be removed because these are unsafe for cyclists and pedestrians.
Public consultation on the changes also includes the planned Eden Quay bus gate, new bus lanes, and new but small and disjointed sections of cycle lanes on the quays. Details can be found on DublinCity.ie and the consultation ends on Monday.
The main changes are on the Nicholas Street approach to the junction. Instead of removing the slip turn as recommended in two national design manuals, Dublin City Council has chosen to retain the slip turn and add a second motoring lane to the turn while keeping the cycle lanes narrower than required under the National Cycle Manual.
The Cycle Manual calls putting cyclists between two traffic lanes “streaming”. It states that the “streaming cycle lane should be 2.0m wide to take account of moving traffic on both sides of the cyclist”, but the council are planing for the streaming cycle lane to be only 1.75m wide.
The kerb-side cycle lane, at 1.5m, will also be below the minimum for such a lane, 1.75m.
The Cycle Manual states that “Streaming is not suitable along HGV routes”, while the planned wider left hand slip turn at the junction is a part “designated HGV route” within the HGV cordon area.
The manual adds: “The permitted weaving area for traffic to cross the cycle lane must be clearly indicated and limited to no more than 10.0m long so as to reduce vehicular speed, and profiled line markings should be considered for the solid white line beyond the weaving area.” The current public plans for the junction, however, show no different coloured area and the permitted crossing area for motorists as defined by broken white lines as 50m long.
