6.14 VERTICAL CIRCULATION

6.14.1 Introduction

This section lists the main principles and standards relevant to the design of vertical circulation including escalators, elevators, stairs, and pedestrian ramps.

A. All stations will require some form of vertical circulation, in the form of ramps, stairs, escalators and elevators.

B. Escalators and stairs must be so situated that they carry passengers directly to the platform at a location convenient for boarding their particular train. Changes of direction should be avoided when possible. These vertical elements must be strategically located at all levels to make this direct route possible.

C. Ultimate quantity of stairs and escalators required in the foreseeable future shall be determined. Even though only some of these escalators will be installed when the system opens to accommodate Design Year loading, the station design must be such that it will permit the ultimate quantity to be installed.

D. Elevators from street level to mezzanine level, and from mezzanine level to platform level, or levels, will be provided as required to make the system accessible to the disabled, and for use by Metro Rail personnel.

E. Vertical circulation elements shall be accessible in compliance with relevant ADAAG and Title 24 (CCR) requirements.

F. At-grade stations shall have, in order of preference, sloping sidewalks, ramps, and/or stairs. Besides stairways, grade-separated or aerial stations, depending on height, will require other vertical circulation elements such as elevators or escalators or both.

6.14.2 Basic Goals

A. Safety, achieved through proper relationship of basic vertical circulation elements and the details of construction.

B. Maximum convenience for patrons, achieved through the establishment of uniform circulation patterns throughout the system.

C. Comfort, achieved through proper sizing and layout of the vertical circulation elements.

D. Facilities designed to provide for the patrons with disabilities.

E. Standard design to facilitate maintenance.

F. Interim maintenance and warranty maintenance agreement with installation contractorscope of work must include the following. Required maintenance shall be of the same standard as all other Metro transit elevators and escalators, and shall include Metro’s standard maintenance check charts as shown in Attachments C and D. The interim and warranty maintenance scope of workagreement shall also cover all repairs and damages above and beyond regular maintenance including vandalism for the period of the agreementone year beginning with ROD.
