MEETING OF TERENURE-RATHFARNHAM AREA COMMITTEE (1)

MOTION NO. 5

MOTION: Councillor T. McDermott

"That the Manager immediately re-instate the right turn from Templeogue Road into Springfield Avenue by applying the same logic as was applied by Dublin City Council in reinstating the right turn into Rathfarnham Road in Terenure Village. The same factors apply to both junctions."

REPORT:

A report analysing the current situation at Templeogue Road and Springfield Avenue and right turn included scenario was previously issued to the members the following was noted:

• The provision of a right turn lane would confine all the other traffic (left turning, straight ahead and bus traffic) into one lane.
• There would be less straight ahead and left turning traffic accommodated at the junction. This would result in traffic queuing back into Templeogue village.
• Journey times for buses would be increased due to additional congestion in the village.
• A new phase is required to permit the traffic to make the turning movement removing ‘green time’ from the remaining movements.
• The provision of the right turn would increase the amount of traffic using Templeogue Village in order to access the turn.
• In the network model comparison of the scenarios, the forecast congestion increased delays by an accumulative 171 hours and caused an additional 516km travelled in an attempt to avoid these delays.
• In the detailed junction model comparison of the scenarios, the reserved capacity was reduced from a current 8% reserved capacity to minus 16% (i.e. 16% more traffic than capacity at the junction)
• The associated congestion would have a negative impact on the environment of the village areas surrounding other approaches to the junction.

In summary in light of the above, it is not recommended to reinstate the right turn.
