INTRODUCTION Many important and long planned transportation and development projects are scheduled for con- struction in Downtown Seattle in the coming years. While these investments are essential to support economic development and job growth and to enhance Downtown’s stature as the region’s premier location to live, work, shop and play, in the short-term they present complicated challenges for con- venient and reliable access to and through Downtown. The Downtown Seattle Association (DSA) and its partners, Historic South Downtown (HSD) and the Seat- tle Department of Transportation (SDOT), seek to ensure that Downtown Seattle survives and prospers during the extraordinarily high level of construction activity that will occur in the coming years.

    PORT AUTHORITY OF ALLEGHENY COUNTY LIGHT RAIL TRANSIT V.4.0 7/20/18 STATION DESIGN GUIDELINES ACKNOWLEDGEMENTS Port Authority of Allegheny County (PAAC) provides public transportation throughout Pittsburgh and Allegheny County. The Authority’s 2,600 employees operate, maintain, and support bus, light rail, incline, and paratransit services for approximately 200,000 daily riders. Port Authority is currently focused on enacting several improvements to make service more efficient and easier to use. Numerous projects are either underway or in the planning stages, including implementation of smart card technology, real-time vehicle tracking, and on-street bus rapid transit. Port Authority is governed by an 11-member Board of Directors – unpaid volunteers who are appointed by the Allegheny County Executive, leaders from both parties in the Pennsylvania House of Representatives and Senate, and the Governor of Pennsylvania. The Board holds monthly public meetings. Port Authority’s budget is funded by fare and advertising revenue, along with money from county, state, and federal sources. The Authority’s finances and operations are audited on a regular basis, both internally and by external agencies. Port Authority began serving the community in March 1964. The Authority was created in 1959 when the Pennsylvania Legislature authorized the consolidation of 33 private transit carriers, many of which were failing financially. The consolidation included the Pittsburgh Railways Company, along with 32 independent bus and inclined plane companies. By combining fare structures and centralizing operations, Port Authority established the first unified transit system in Allegheny County. Participants Port Authority of Allegheny County would like to thank agency partners for supporting the Light Rail Transportation Station Guidelines, as well as those who participated by dedicating their time and expertise.
