College Green Bus Gate Traffic Management Options

Road Safety Reviews & Audits
Dublin City Council
The project was situated in the South side of Dublin City Centre between the junctions of Trinity Street and D’Olier Street and consisted of upgrading existing pedestrian crossings and creating new pedestrian crossings across College Green from Church Lane to Foster Place, and a new pedestrian crossing at Trinity Street.


DBFL were initially commissioned by Dublin City Council (Quality Bus Network Project Office) to undertake a road safety review of five (5) potential traffic management layout options regarding the introduction of a ‘Bus Gate’ at College Green. The proposed ‘Bus Gate’ incorporating a range of different but integrated traffic management measures seeks to introduce a strategic bus priority initiative through the segregation of bus services (in addition to cyclists, taxi’s, and coaches) from private motor vehicles with the key objectives of enhancing peak period journey times in parallel with delivering journey time reliability for public transport bus services operating through this core area of the city centre. In parallel with new traffic management layout at College Green, the scheme proposals also included supplementary traffic management measures to accommodate the reassignment of private motorised vehicles which would no longer be permitted to travel through the highly sensitive College Green area during peak times.


Following the initial preliminary options safety review, DBFL were subsequently retained to undertake a Stage 2 Road Safety Audit (RSA) of the identified preferred scheme prior following its detail design but prior to the commencement of the physical construction works. DBFL also undertook the role of PSDP at the request of Dublin City Council.


Following the incorporation of DBFL’s RSA recommendations the identified scheme included (i) the reassignment of road carriageway space; (ii) modifications to road junctions, street widths and traffc islands, (iii) upgrading of existing & new pedestrian crossing facilities, includes widened crossings, tactile paving, new signals, ducting and boxes; (iv) resurfacing of the carriageway with new road makings and anti-skid; (v) new footpath surfaces and (vi) new signage strategy including VMS covering information (Car Parking), direction and regulatory requirements.
