Th traffic and transportation issus in th Stratgic Dvlopmnt Zon Planning Schm (Chaptr 5) provid an ovrviw of th currnt documnt as wll as th Mobility Managmnt Plan prpard by AECOM. 1.2 Dvlopmnt Location Granggorman is an ara of approximatly hctars locatd north of th Rivr Liffy and south of th Royal Canal, approximatly 1 kilomtr from Dublin s City Cntr. Th sit is split by th road Granggorman Lowr and Uppr. Th Granggorman sit is boundd by Circular to th north, Prussia and Stonybattr to th wst, and to th south. Figur 1.1 Granggorman Sit Location 1.3 Dvlopmnt Proposals Th dvlopmnt proposals involv th provision of 21st cntury facilitis to accommodat th nds of th Halth Srvic Excutiv (HSE), Dublin Institut of Tchnology (DIT), and th local community. Th sit is currntly occupid by St Brndan s Hospital, a psychiatric hospital ownd and run by th Halth Srvic Excutiv. Much of th rst of th sit is undvlopd and can b considrd Brownfild. Th buildings which ar in us ar no longr suitabl for modrn mntal halthcar facilitis. DIT currntly occupis a total of ovr 40 individual buildings around Dublin city cntr. This divrsification of building locations gnrats significant travl dmand across th city. For DIT th Granggorman dvlopmnt will offr a consolidatd campus nvironmnt which can play an important rol in gnrating sustainabl travl pattrns. To support th HSE and DIT facilitis an appropriat lvl of mixd us (rtail and commrcial) dvlopmnt is rquird. This will b largly providd at th Broadston dg of th sit in ordr to achiv th ara s optimal dvlopmnt potntial in lin with th City Dvlopmnt Plan.

11 Introduction

12 AECOM Granggorman Ara Transport Assssmnt 9 Capabilitis on projct: 2 Introduction 2.1 Background Th Granggorman sit is a prim asst locatd in th hart of Dublin city. Th Dublin Institut of Tchnology has volvd sinc its stablishmnt in 1992 such that it now oprats som 6 facultis togthr with substantial rsarch cntrs across ovr 40 locations in Dublin. Th DIT Stratgic Plan and its subsqunt sris of thr yar Dvlopmnt Plans undrpins th nd for rlocation of DIT to a nw intgratd campus. Granggorman was idntifid by th Govrnmnt as an idal location for a nw intgratd campus clos to th city cntr and capabl of dlivring all that th DIT Stratgic Plan rquird. Th rdvlopmnt of th hctar Granggorman sit to accommodat both DIT s ducational and HSE s halthcar uss, and its potntial to contribut to th conomic growth and connctivity of th nighbourhood and city has bn rcognisd as a ky public projct in th currnt National Dvlopmnt Plan and is an objctiv of th Dublin City Dvlopmnt Plan Study Objctivs Th objctivs of this Transport Assssmnt ar as follows: - To dscrib th xisting transportation nvironmnt, highlighting ky dficincis in th transport ntwork and noting any futur schms or initiativs which will impact on gnral traffic and transport pattrns; - To dscrib th dvlopmnt proposals, and how thy hav bn dvlopd to tak account of xisting and futur transport nds through th locality; - To quantify th likly traffic and transportation dmand that will aris as a rsult of th dvlopmnt proposals, and to idntify th impact of such dmand on th ntwork; - To highlight thos aras whr th impact of th dvlopmnt can b dfind as significant, and subsquntly to idntify suitabl masurs, if any, to mitigat thos impacts. Th mphasis of this rport has thrfor bn on assssing th advrs impacts of th schm, idntifying th masurs that can b incorporatd into th schm to mitigat such impacts, and undrstanding th rsidual impacts of th schm with such masurs in plac. In addrssing ths qustions, th main critria for xamining rlvant impacts hav bn as follows: - Public Transport Will th schm complimnt or conflict with xisting and proposd public transport? Is sufficint capacity availabl to accommodat a phasd dvlopmnt of th schm? - Local road and junction capacity Is congstion or significant quuing nvisagd through th junctions in th futur, and will such congstion and dlay b xacrbatd by th dvlopmnt proposals? - Dmand Managmnt What masurs would b most succssful in rducing th dmand for travl arising from th dvlopmnt proposals? How can th travl dmand b influncd as th dvlopmnt progrsss through its phasd dlivry? - Rsidual impacts Ar thy significant and can thy b managd ffctivly? Th Transport Assssmnt is supportd by traffic modlling as appropriat to assss th capability of critical road junctions within th study ara to accommodat th xpctd lvls of traffic. 2.3 Study Mthodology Th mthodology for this study is st out in th figur blow. Th mthodology was dvlopd following consultation with National Transport Authority and Dublin City Council.

Th ast sid of th sit is accssd from Granggorman Lowr and Morning Star Avnu. Limitd accss is providd to on building (Connolly Norman) from Circular. Whil adquat pdstrian facilitis ar gnrally providd within th surrounding road ntwork, th dvlopmnt sit currntly suffrs from a lack of prmability causd by limitd accss and th boundary walls surrounding th sit. Public transport accssibility is dlivrd by bus srvics along Prussia, Constitution Hill and Circular, and th LUAS Rd lin which provids thr stops within a 12 minut walk tim from th sit. Th xisting traffic circulation systm south of th subjct sit is quit complx. It should b notd that a bus lan is in opration southbound on Blackhall Plac btwn its junction with King and Ellis. Th xisting junction arrangmnt btwn Gorg s Lan and is a major constraint to accss from th south. At prsnt traffic travls north on Gorg s Lan and thn right only onto th astbound on way traffic of. At prsnt Granggorman Lowr can only b accssd via Stonybattr and thn.

On-sit parking will b introducd on a pro rata basis in lin with th proposd provision outlind in Tabl 4.3 and th quantum of dvlopmnt compltd. Th proposd car parking aras will b managd and dsignatd for diffrnt aspcts of th proposd uss so as to control and limit vhicular accss to th sit, thrby managing th traffic impact of th dvlopmnt. Initially, a surfac car park will b constructd in th ara to th of th sit dsignatd for latr HSE facilitis aftr it is no longr rquird as a sit compound. Similarly, an intrim surfac car park will b constructd adjacnt to th xisting Lowr Hous building to th Southast cornr of th sit.

In gnral, only vhicls with a parking prmit or prior approval will b allowd th us of a parking spac at th Granggorman sit. Each stakholdr will b assignd th quantum parking spacs as shown in Tabl 4.3 abov. Th stakholdr is thn rsponsibl for th allocation of ths spacs to ithr staff or studnts. Th mthod of parking prmit allocation is at th stakholdr s discrtion. Howvr, th stakholdr will not b prmittd to issu anymor prmits than th outlind allocation. Clamping will also b mployd at th Granggorman sit to dtr inappropriat parking. Th parking prmit systm will rmov th possibility of motorists driving to th sit spculativly for parking spacs.

Th approach to th dvlopmnt of an appropriat Mobility Managmnt Stratgy is th mploymnt of th wll-documntd Carrot and Stick approach. Such an approach tackls th transport problm from both nds. It utiliss th Carrot which incorporats th improvmnts in altrnativ mods of travl, ffctivly opning up transport options for commutrs, and th Stick which discourags th us of car transport for thos who do not nd it. Carrot masurs incorporat masurs to facilitat Public Transport, car sharing, flxibl travl tims, and an improvmnt to th walking and cycling nvironmnt. Stick masurs includ car parking rstraint and othr fiscal masurs. Both lmnts of this approach ar rquird to achiv a succssful rsult. Th parking provision for th Granggorman SDZ will act as a powrful mobility managmnt masur as it has bn calculatd spcifically to nsur against an ovrprovision of parking and a rsultant ovr rlianc on th privat vhicl. This will b supplmntd by masurs to ncourag mor sustainabl mods of transport such as walking, cycling and th us of public transport. It is intndd that all stakholdrs will appoint a Mobility Managmnt Coordinator (MMC) who will promot all aspcts of th Mobility Managmnt Plan (MMP) within thir ara of th SDZ.

If a location has limitd public transport options and is outsid rasonabl walking / cycling distancs to th campus, thn th car modal shar would b considrd most dominant. Howvr, th modal shar of th car is rstrictd as a rsult of th proposd parking provision for DIT of 350 spacs and as a rsult is a major factor in th gnration of a modal split for ach rgion and consquntly th ovrall modal split.
