Baker Street Two Way Post-implementation monitoring strategy

1 Baker Tw Way Pst-implementatin mnitring strategy During the last cnsultatin in July 2015, varius issues and cncerns were raised. Respnse t the general traffic and envirnmental issues raised were prvided as part f the cnsultatin respnse reprt. Hwever, a lt f cncerns were related t specific junctins and lcatins. In rder t address these cncerns, design changes at sme lcatins have been develped. These design changes have been discussed with residents grups, amenity grups and key stakehlders and are nw being cnsulted upn in this phase f cnsultatin. Cncerns were als raised regarding traffic impact at a small number f ther lcatins. During discussins with residents grups, amenity grups and stakehlders, it was agreed that instead f prpsing changes at these lcatins, these sites will be mnitred as part f the pst-implementatin mnitring strategy. This mnitring strategy wuld help t determine whether r nt cncerns raised by cnsultees regarding rat-running traffic have been realised. If it is determined that the prpsed scheme has led t significant traffic impact, in terms f increased rat-running n lcal rads, then additinal mitigatin measures can be cnsidered. It is als prpsed t have a cntinued dialgue with the residents grups, amenity grups and stakehlders s that residents and business cncerns can be addressed. Thrughut the cnstructin and implementatin f the Baker Tw Way scheme (BS2W), and fr at l 6 mnths fllwing pening, there will be regular and in sme cases cntinuus mnitring f cnditins acrss the area t ensure that: the Baker Tw Way scheme is delivered with minimal disruptin t residents, businesses and visitrs t the area; the Baker Tw Way scheme, pst-implementatin, perates bradly as expected and des nt give rise t significant traffic impact, especially high levels f inapprpriate vehicle rat-running n lcal rads (which was a cncern fr a number f previus cnsultees); if significant and unexpected traffic impact ccurs, then suitable mitigatin measures are identified and implemented. This mnitring strategy wuld als help t assess the impact f the prpsed measures and the success f the BS2W scheme against the stated bjectives. This will be achieved thrugh: a variety f dynamic and CCTV traffic mnitring, traffic surveys and ther data gathering, assessment and review; regular liaisn meetings with amenity and resident grups and key stakehlders; Over the next cuple f years, there are likely t be changes t traffic patterns acrss the rads f central Lndn as a cnsequence f the building and implementatin f ther majr transprt infrastructure initiatives, such as the Mayr f Lndn s Cycle Superhighways and the West End Prject (Tttenham Curt Rad Tw Way). Because f this, it will be essential t gather traffic data that accunts fr these changes, s that any impacts f the BS2W prject can be assessed independently. T accunt fr as many changes leading up t the start f BS2W wrks as pssible, new data gathering will be carried ut just befre the wrks start, and then again at a suitable mment after the scheme is pened, fllwing an apprpriate settling-in perid. The mnitring strategy will cmprise the fllwing: Cntinuus dynamic traffic management using CCTV and the TfL Urban Traffic Cntrl SCOOT system, t ensure that traffic cngestin is avided as far as pssible;

2 Baker Tw Way Pst-implementatin mnitring strategy Vehicle traffic flw and jurney time surveys n streets and at junctins acrss the netwrk, particularly n streets where residents have expressed cncern ver ptential rat-running; Cyclist and pedestrian flw and jurney time surveys alng streets and at junctins acrss the area; Pedestrian envirnment review (PERS); Vehicle speed surveys; Bus perfrmance and bus patrnage, barding and alighting surveys; Rad Safety Audits; Accident data analysis (cntinuus, fr at l 3 years t establish impact f scheme); Review f reprts f crime and petty theft; Parking and lading behaviur. Based n previus cnsultatin respnses, alternative scheme prpsals are nw presented that prvide mitigatin fr a number f cncerns, namely: Tauntn Place/ A41 Glucester Place junctin banned right turn int Tauntn Place; Ivr Place/ A41 Glucester Place junctin pririty cntrlled junctin with relcated Zebra crssing Ivr Place/ A41 Park Rad junctin maintain current permitted turning mvements, mdificatin t full traffic signal cntrl, revisins t cyclist facilities, new pedestrian crssing, enhanced public realm; Clarence Gate/ A41 Park Rad junctin revisins t junctin t match changes at Ivr Place junctin, revisins t cyclist facilities, additinal pedestrian crssing and a green man at all pedestrian crssings, with cuntdwn timer stage; Melcmbe Place, Drset Square and Melcmbe ftway widening, imprved crssing facilities and enhanced public realm; Melcmbe Place, Drset Square and Melcmbe ptential fr further ftway widening thrugh lss f parking; A501 Marylebne Rad/ A41 Glucester Place junctin retentin f left turn frm Glucester Place and imprvements t staggered crssing ver Marylebne Rad west side; A501 Marylebne Rad/ Balcmbe / Upper Mntagu junctin prvisin f new straight-ver crssing; Yrk / A41 Glucester Place junctin retentin f tw way traffic n Yrk west f Glucester Place. Nevertheless, if it is determined frm the mnitring that the scheme has led t unfreseen and undesirable traffic impact, in terms f increased rat-running n lcal rads (as ppsed t imprved accessibility fr lcal traffic), then apprpriate mitigatin measures will be cnsidered. Based n cnsultatin respnses frm the riginal prpsal, sme ptential further measures have already been identified and currently cmprise: Prhibitin f suthbund right turns frm Glucester Place int Ivr Place and Huntswrth Mews, due t cncerns fr rat-running thrugh the nrth Marylebne area; Clsure f the suthbund thrugh rute n Glentwrth, due t cncerns that traffic wuld rat-run t avid queues and delays n Baker and Allsp Place;

The junctins identified belw wuld be useful nt nly t verify frecasts and understand wider impacts f the scheme, but als will prvide invaluable data as part f a brader befre-and-after study.

These surveys wuld be useful t assess the value f the new facilities. This data will als be used t carry ut Pedestrian Cmfrt Level analysis n Baker t demnstrate benefits f public realm imprvements. Befre-and-after pedestrian crssing data required at: Ivr Place/ Glucester Place (if traffic signal junctin is intrduced)

This wuld require befre-and-after pedestrian crssing data at: Baker junctins with Yrk Crawfrd Drset Blandfrd Gerge Fitzhardinge Wigmre Bus passenger (BODS) data will be used frm all bus stps within the crridr t assess bus patrnage (barding and alighting) and verify the benefits f prviding 2-way bus services n Baker (as ppsed t split nrthbund and suthbund services). The data will shw whether r nt there is a change in bus passenger numbers and if the services becme mre attractive nce they are n a single

The review may lead t ptential revisins/ alteratins t schedules, number f services, etc. The perfrmance f the scheme will be reviewed ne year fllwing implementatin, using a Rad Safety Audit Stage 4. Analysis f casualties and cllisins fr the three years befre and fllwing implementatin f the scheme will als take place. In rder t expand the limited data that is available n the wider benefits f ne way t tw way street cnversins, it is prpsed t cllect further data t verify and validate the bjective and subjective frecasts f benefits that are expected t be achieved thrugh the cnversin, and t prepare a cmprehensive reprt n the prject. These surveys are: Vehicle speed surveys use speed measuring device t determine if excessive speeding issues are reslved n Baker and Glucester Place. This might lead t further cnsideratin f 20mph zne, traffic calming measures, traffic signal timing strategy review. Jurney times alng the Glucester Place and Park Rad/Baker crridrs. These wuld be useful t cmpare t VISSIM mdelling results, wuld validate the prpsed mdel frecasts and identify if further signal timing alteratins might be f benefit, particularly fr bus peratins. T a great extent, TfL will use UTC t adapt signal timings t prvide the ptimum strategy, hwever a detailed jurney time study wuld greatly assist with ptential imprvements. New rigin-destinatin data at a gd level f detail. This data wuld determine whether r nt the scheme results in any significant change t travel patterns acrss the area, and identify thrugh and lcal traffic. Parking and lading behaviur t determine if there is adequate prvisin and pssible nncmpliance issues. As stated abve and in additin t the technical analysis, it is als prpsed t have a cntinued dialgue with the residents grups, amenity grups and stakehlders s that residents and business cncerns can be addressed.
