Specifications include, but are not limited to: The purpose of this RFP is to procure an intelligent transportation system (ITS) hardware and software system with associated services. The proposed system will provide for a dynamic parttime shoulder use (PTSU) system operating along Interstate 95 (I-95) northbound from Exit 5 in New Hampshire to Exit 3 in Maine and along I-95 southbound from Exit 2 in Maine to Exit 5 in New Hampshire. This proposed system includes ITS hardware deployed along I-95 and the Maine Turnpike, along several approach ramps, and along arterial streets in Kittery, Maine and software integration and updates to the New England Compass Advanced Transportation Management System (ATMS) to manage and monitor the PTSU system. To support the ITS systems described above, the existing microwave wireless communication infrastructure along the I-95 bridge over the Piscataqua River shall be modified. The existing communication design is provided in Appendix I. This Project includes installation of two communications equipment shelters (one in Maine and one in New Hampshire), new and modified communications systems, and a new climbable antenna mounting structure. This new climbable antenna mounting structure shall provide line of sight access to the Hobbs Hill Water Tank at Pease and to the Sarah Mildred Long (SML) Bridge. New microwave wireless paths to support multiple ITS devices on the I-95 High Level Bridge (HLB) are shown in Appendix J. The proposed PTSU system will consist of an interconnected system of several ITS devices, including closed circuit television cameras, dynamic message signs, blank out signs, motor vehicle detection systems, a motorized gate system, overhead lane use signals, and flashing beacon signs. The PTSU system will also consist of infrastructure improvements including signs and sign supports, concrete foundations, guardrail, conduit and pull box systems, erosion and sediment controls, temporary traffic controls, and related design and construction activities.
