TriMet PMLR
Minimizes transit delay, increases ridership, and improves safety.
Quick Facts
Seven mile MAX Orange line connects Milwaukie to Portland’s South Waterfront District and downtown Portland
Alignment crosses the Willamette River on the new Tilikum Crossing, Bridge of the People, which carries light rail trains, the streetcar, buses, bicycles, and pedestrians
Most of alignment is along an active Union Pacific freight corridor, which includes the only at-grade crossing of a light rail system and a heavy-rail line in the Pacific Northwest
Following a public vote against the LRT extension to Milwaukie, DKS assisted in the critical task of building public consensus by performing transportation analyses on the alignment and operations. Our fact-based approach was successful in obtaining public buy-in and moving forward with each phase of the South Corridor project: I-205, Transit Mall and PMLR
Results
Built public and agency consensus to successfully advance this project
Creates a safe multimodal corridor in spite of complex traffic engineering, circulation, and access issues and the heavy rail interface
Minimizes cut-through traffic and parking infiltration in neighborhoods
Improves light rail operations, travel times, and reliability while reducing impacts on autos, buses, bicycles, parking, pedestrians and businesses
Increases transit ridership by creating an innovative design that ensures safety and integrates pedestrians, bicycles, and the streetcar
Minimizes transit delay, increases ridership and improves safety
Our Work
Led transportation engineering services from concept planning through to environmental approvals, design and operational implementation
Performed alternative analyses by integrating advanced traffic analysis tools (Visum, EMME/2, Synchro, Vissim, SimTraffic, ArcView and aaSidra) to guide the decision process and build public consensus
Developed consolidated design of three at-grade crossings into one at-grade crossing at the 8th Ave., Division St., and Division Pl. intersection
Developed grade crossing applications, including quiet zone applications at 12 locations
Performed specialized traffic engineering analyses for bus access along dedicated trackway and intersection operations
Performed detailed traffic operational assessment
Designed dedicated bicycle signals and bicycle detection
Designed traffic signal phasing, lighting, signing, striping, and channelization to improve operations and safety
Designed interconnect plans to communicate between light rail and traffic signal systems
