J -- I-95 TRAFFIC AND INCIDENT MANAGEMENT SYSTEM MAINTENANCE SERVICES. The Pennsylvania Department of Transportation (PennDOT) will be requesting proposals to maintain the I-95 Traffic and Incident Management System (I-95 TIMS) located along the section of I-95 traversing the metropolitan Philadelphia area. The traffic control center (TCC) is located adjacent to the PennDOT 6-0 building at St. Davids, PA. The maintenance services will include, but not be limited to preventive maintenance, response maintenance, and emergency repairs. It is anticipated that the duration of the maintenance services will be for at least 18 months. The I-95 TIMS consists of 12 closed circuit television (CCTV) cameras, four variable message signs (VMS), TCC, and T-1 and dial-up telephone lines leased from the local telephone company. A typical remote CCTV camera location includes a pole-mounted or sign structure-mounted camera assembly and a ground-mounted camera control cabinet that houses CCTV, communication, and electrical equipment. The VMS system includes two clustered light-emitting diode (LED) and two fiber optic technology based signs. The signs are mounted on overhead structures and the VMS control cabinets are ground-mounted adjacent to the sign structures. The TCC consists of two rooms - Room 1 housing operator workstations for CCTV, VMS, and communications systems and Room 2 housing communications equipment enclosures, uninterrupted power system, and electrical and telephone termination equipment. Information for preparing bids is expected to be available by mid September 1995 for a Fall 1995 bid opening. For further information please call Mr. Karl Ziemer at (610) 989-9326. (208)
