INTELLIGENT TRANSPORTATION SYSTEMS (ITS)

DRMP is providing professional engineering services for the design of upgrades and expansion of a fiber optic traffic signal system (ITS).  The project extends along Park/Johnston Road from Community House Road to Charlottetowne Avenue (Pineville-Matthews Road) for a distance of nearly 11 miles including 30 signalized intersections.  The proposed improvements include provisions for a 96 pair communication fiber and 15 CCTV cameras.  DRMP’s scope of services includes developing fiber optic design plans, splice details, special provisions and engineer’s estimate of probable construction cost (preliminary and final), CCTV camera design, railroad permits (where applicable), utility make-ready plans, preparing construction documents for the implementation of the traffic signal system projects, coordinating utility make-ready work, reviewing contractor submittals and assisting with construction administration/inspection during construction.

DRMP designed the installations of Dynamic Message Signs along the Mainline Turnpike and various major arterial roadways having interchanges with the Mainline Turnpike.  This work included the coordination with various agencies such as FDOT Districts and Counties for development of fiber sharing agreements for use in communicating with some of the arterial signs.  Wireless communications with firewall protection were also used as another source of communications.  Structural designs were prepared for all sign structures both cantilever, mid span truss, full span truss and box trusses.  Major emphasis was placed on utility coordination to avoid conflicts.  Detailed specifications were developed for all components.  Coordination with various other construction projects was performed to ensure the sign structures would not conflict with the proposed construction.  Service Plaza Information Systems were also designed as part of this project to disseminate travel information along the Turnpike system to the traveling motorists.  This project included the installation of Ethernet switches, terminal servers, video monitors and CCTV’s inside each of the service plazas.

DRMP designed the 25 mile Intelligent Transportation System (ITS) along the Polk Parkway utilizing gigabit Ethernet communications with field installations of CCTV sites, Vehicle Detection Systems, Travel Time Systems, and Highway Advisory Radio (HAR) systems.  Data transmission for all field devices was aggregated at a Master Hub site for transmission via a Long Haul Edge Switch back to the Turnpike Enterprise Traffic Management Center on the Mainline Turnpike in Orange County.  DRMP provided engineering services including permitting for the crossing of railroad right-of-way, county right-of-way, and navigable waterways, designing electrical services for all field devices and developing an intricate grounding system for protection from lighting strikes.  Detailed specifications were also developed for all communications and field devices.

This project included the design for the installation of 26 Dynamic Message Signs and CCTV sites providing continuous coverage of various routes throughout the county.  Prior to finalizing the design for the CCTV installations, the County Commission voted to amend the contract to remove the installation of the CCTV sites.  The design of the DMS signs included the installation of new Fiber Optic Communications cable both aerial and underground, controller cabinets, and  layer 2 ethernet switches.  All field devices were supplied with power service from a circuit breaker connection which was designed to support a full load condition of all devices connected to.  Surge suppressors were installed on both the circuit breakers supplying the power service and the main circuit breaker housed inside the cabinet.  The signs were designed to be mounted on standard Mast Arm Assemblies in order to keep the construction costs to a minimum.
