The work to be performed on this project consists of furnishing, installing, testing, and interconnecting a Computerized Transportation Management System. This project covers the IH 45 Gulf Freeway from Clear Creek to 61st street in Galveston. Components of the system are as follows: - Dynamic Message Signs - CCTV Surveillance - Fiber Optic Communications - Voice Communications - Interconnection with Houston TranStar Control of the systems will be via equipment located in the satellite control center as shown on the plans. Communications to the various hubs from the satellite control center will be via fiber optic cable. Video transmissions will also be via fiber optic cable. (1) Dynamic Message Sign System. The dynamic message sign (DMS) work on this project shall consist of providing and installing dynamic message signs, flashing beacons, field controllers, sign support structures, foundations, communications cable, modems, power cables, service poles, conduit and cabinet foundations. The dynamic message signs supplied on this project shall be of the fiber optic technology. Each sign shall display three (3) lines of message text each with fifteen characters. Two (2) flashing beacons utilizing Light Emitting Diode LED technology shall be installed on each sign. Control of DMS shall be from the existing DMS master controller installed at the Satellite Control Center and from the DMS remote terminal installed at Houston Transtar. (2) CCTV Surveillance System. The CCTV surveillance system shall consist of CCTV cameras to be located at strategic locations along the freeway. These cameras will furnish visual surveillance to verify that the various components of the system are in their correct mode. They shall also provide visual confirmation of free-flow conditions, incidents, or congestion along the freeway and frontage roads. The cameras shall be mounted on structures dedicated to the CCTV cameras. The following remote control features shall be provided for each camera: Pan, tilt, zoom, focus, iris control,

2 and camera power. The video signal from the cameras shall be transmitted to the satellite control center via fiber optic cables. Depending on the locations of the cameras, the transmission technique shall be baseband, frequency modulation/frequency division multiplexed (FM/FDM), or both. Personnel at the satellite control center and at Houston TranStar shall be able to monitor and control each of the cameras, one at a time, with the video monitors and a video switcher. Camera controls in the field shall be accomplished with the local control panels of the camera controllers. Camera controls in the satellite control center and at Houston TranStar shall be via central control panels. Control signal transmissions shall be via fiber optic cable. (3) Voice Communication System. The voice communications system shall provide one (1) voice channel and shall consist of equipment in the satellite control center and portable field equipment for field personnel to use in any of the field cabinets. Voice Communications shall be via the voice orderwire circuits of the D/I muldems in the communications hub buildings and in the Satellite Control Center. Each field cabinet shall have a voice communications Jack. Personnel at the satellite control center shall be able to talk with field personnel at any hub or field cabinet at the same time. (4) Fiber Optic Communications System. All of the field equipment shall be interconnected with the satellite control center equipment via fiber optic cable. The cable shall be connected to the required transmitters, receivers, D/I Muldem, and other interface equipment in "communications hubs" to be located as shown on the plans. Command data from the satellite computer shall be demultiplexed in "communications hub" locations for distribution to the various field equipment. Data from the field will also be collected and multiplexed in the "communications hubs" for transmission to the satellite computer. All field equipment between the "communications hubs" shall be interconnected to the "communications hubs" with twisted wire pair (TWP) cable. At the satellite control center, the fiber optic cable shall be connected to the fiber optic transceivers and a D/I Muldem which in turn shall be connected to the following equipment:

3 (a) DMS Master Controller (b) CCTV Central Equipment (c) Voice communications equipment (5) Interconnection with Houston TranStar.
