1.8 LegislationTransport facilities shall be designed to comply with the laws and regulations of the Republic ofSingapore.Page-5/31May 2013Section 2 of Architectural Design Criteria – Revision A2
Page-6/312 ACCESSIBILITY2.1 Pedestrian AccessDesigners shall ensure that transport facilities :- Are in accordance with the Building Control Regulations- Are accessible to people with disabilities in accordance with the current edition of the Code onAccessibility in the Built Environment.- Are modally integrated.- Have a clear sequence of spaces each indicative of their function.- Are designed in accordance with the principles outlined in the Guidelines for Enhanced BuildingSecurity by MHADesigners shall ensure that stations are accessible according to the Guide to the layout of the tactileGuidance System in MRT and LRT Stations.Each transport facility building shall have at least one designated barrier free route leading into thebuilding and linking to all possible passenger destinations within the building in compliance with theCode on Accessibility in the Built Environment.All disabled access routes into the transport facilities shall, where possible, be via the main entrance.Application of multiple barrier free routes shall be considered for transport facilities with multiplemajor passenger flow routes.Doors astride the tactile route shall be automatic or permanently fixed open. Automatic doors shall besliding in preference to swing doors.All doors accessed by the public shall require a maximum force of 22N to open or close.2.2 Congestion2.2.1 GeneralAll congestion modeling and calculations shall be based on projected passenger figures provided by theAuthority or site survey data weighted to suit future site loadings to the approval of the AuthorityDesigners shall assess predicted passenger movement, capacities and waiting times at circulationelements during peak operations.Designers shall ensure clear widths leading to all transport facilities allow uncongested access.Station designers shall demonstrate that platforms can be cleared prior to the arrival of the next trainduring normal peak operations.The capacity and flow per escalator and fare gate shall be as advised by the Authority. The quantity ofboth escalators and fare gates shall be defined by the designer to meet the projected patronage figures.Future expansion or removal of escalators and fare gates shall be included in the design to cater forfuture projected changes in demand. Facilities for the delivery, installation or removal of suchelements shall be allowed for and highlighted in the design.2.2.2 SimulationCongestion and pedestrian flow within and leading to all transport facilities shall be assessed usingpedestrian simulation software against the maximum projected pedestrian numbers. Reassessmentsshall be undertaken given any significant changes to a design or projected passenger numbers.Simulations shall be carried out for both the peak evening and morning hours or any other criticalperiod as advised by the Authority. Within the peak hours being simulated a peak within the peakshall be include by introducing a 1.3 weighting to the central 20 minutes of the simulated hour.The influence of walls, balustrades or other obstructions shall be considered in the simulation by theinclusion of a 0.3 meter zone beyond the obstruction were there is no pedestrian movement.The influence of shops alongside access routes shall be considered in the simulation by the inclusion ofa 1 meter zone beyond the shop front were there is no pedestrian movement.The influence of waiting and queuing areas such as for ticket machines or other vending machines shallbe allowed for to the approval of the Authority.The simulation shall include any interfacing station or bus interchanges (both existing and underconstruction) and make allowance for all trains and pedestrian movements within the completedinterchange. Recommendations for retrofitting measures within the existing infrastructure shall beincluded in the report.The scope of the study shall include allowance for redundancy in the provision of escalators. Multiplescenarios shall be simulated and reported in which any one escalator is unavailable to cater foroverhaul (Can't be used as a staircase).May 2013Section 2 of Architectural Design Criteria – Revision A2
