Transpo evaluated the Renton Plant’s on-site multi-modal circulation, in response to concerns about pedestrian safety. The site includes a wide mix of transportation uses, including vehicle traffic, truck deliveries, parking, pedestrian travel, forklift traffic, train loading and unloading, dolly use, and towing of airplane sections. Transpo completed an extensive site review process with Boeing team members and stakeholders, and prepared a State of the Plant report documenting existing conditions, analysis methodologies and recommended solutions. Transpo was subsequently retained to prepare signing and striping specifications for site-wide use, and to design specific solutions at 13 key locations throughout the plant’s exterior, as well as along all major transportation aisles within the plant’s primary manufacturing buildings.
 As a follow-on task to the project, Transpo conducted a separate train crossing safety study. The train’s entry and travel through the site was reviewed, together with fuselage storing and retrieval operations. Site operation as a whole was reviewed, together with each location where train sections were required to cross other modal paths. Since the train travels through the plant at the same grade and through the same areas as significant pedestrians, vehicle and fork lift corridors, and because it was determined that sound reverberation was of concern, three levels of improvement options were recommended – passive signing, active signing, and control signing.
