NNS I ) <br /> ROADWAY SAFETY IMPROVEMENTS <br /> We are fully knowledgeable in the latest Federal requirements for guardrails and other roadway features.We <br /> have trained staff familiar with AASHTO's Roadside Design Guide and with the National Cooperative Highway <br /> Research Program's Report 350. <br /> TRANSPORTATION PLANNING/TRAFFIC ENGINEERING <br /> The Honolulu office has extensive experience in transportation planning studies including traffic impact <br /> studies, alternative analyses,transportation system management(TSM) studies, high occupancy vehicle <br /> (HOV) planning and transit planning. Our traffic engineering experience includes highway and intersection <br /> capacity analyses,traffic signal design and optimization, and the development of maintenance of traffic <br /> plans. <br /> TRAFFIC IMPACT ASSESSMENT SERVICES <br /> We have conducted numerous traffic impact analyses throughout Hawaii and are aware of the types of issues <br /> that are often raised. Our strengths lie in our ability to listen to those issues and in our comprehensive <br /> knowledge and experience base that help us develop cost-effective solutions to those issues.The Waimea <br /> Circulation Study is an example of our ability to address community concerns. <br /> TRAFFIC SIGNAL DESIGN <br /> WSP is experienced in traffic signal design for standalone and for multi-signal systems applications. Our staff <br /> is familiar with state-of-the-art signal design elements and has completed traffic signal installations in <br /> Hawaii.We are familiar with local practices for signal design and in preparing PS&Es according to HDOT and <br /> FHWA standards.We are also committed to thoroughly understanding the project issues so that the traffic <br /> signal is well integrated with the intersection in terms of signal phasing, signal timing, and intersection <br /> channelization. <br /> TRAFFIC CONTROL <br /> Many design and construction projects require complex traffic control plans or detour plans to re-route <br /> traffic. The transportation/traffic group provides expertise in providing innovative and creative solutions to <br /> minimize traffic impacts during construction. The Farrington Highway Improvements at Nanakuli Avenue <br /> and Haleakala Avenue and Interstate Route H-1 Rehabilitation projects are examples of our capabilities in this <br /> area,where high volumes of traffic flow had to be maintained during the construction of highways and <br /> complex highway interchanges in urban areas of Honolulu. <br /> CONSTRUCTION/PROGRAM MANAGEMENT <br /> CONSTRUCTION MANAGEMENT <br /> Our firm provided construction management services for the Interstate Route H-3 Trans-Koolau Tunnel <br /> project which was constructed through six separate construction projects:Halawa Approach and Tunnels, <br /> Haiku Approach and Tunnels,Ventilation Fans, Traffic Control Systems,Tunnel Mechanical/Electrical/ <br /> Architectural Finishes, and Exploratory Tunnel Finishes. Our construction management staff dealt with the <br /> complex challenges of coordinating and interfacing unique construction contracts into the final tunnel <br /> product.We provided the overall construction management of multiple contractors, construction <br />
