Presentation on theme: "Chattanooga CCTV Early Deployment"— Presentation transcript:
1Chattanooga CCTV Early Deployment Jim Floyd, Volkert & AssociatesSteve Meyer, P.E. Volkert & AssociatesPurpose: to examine necessary considerations during the process of constructing a CCTV system, and how TDOT solved problems along the way.
2Hamilton County CCTV(There is one picture with numbers and one without, which do you want?)
3Overview of Design Concept 63 Camera SystemFirst System in Tennessee to Utilize Ethernet Protocols to Each Field DeviceField Hardened RoutersLeased T1 LinesDome CamerasDemarcation PointsLayout of Temporary TMC
4Design Concept 63 Camera System Ethernet Protocol Dome Cameras Ultimate system designed to include 148 camerasIncluded in Regional ITS Architecture.Chattanooga’s system is the first to use Ethernet protocols down to the camera.Allows for interoperability.Field hardened equipment, no HUTS.
5Design Concept At each Demarcation Point Field-hardened routers Single and dual-camera demarcationsRouters could be configured to serve 2 camerasCamera has 360 degree pan visibility and 184 degree tilt visibility, compare to GA Navigator at 160 degrees.Each camera is IP addressable.Reduction in number of Routers needed.Possibility of router to serve more than two cameras, only two currently proven to work.Demarcation point allows termination of camera inputs and outputs to interface with the power and communication utilities.
6Design Concept BellSouth provides leased T1 lines TDOT Plans Future Fiber BackboneTDOT’s future fiber backbone will allow for a system which includes Dynamic Message Signs and Roadway Traffic Sensors, and Camera Video Surveillance (info taken from TDOT web site)
7Design Concept Layout of Temporary TMC System Fully Equipped to Assist Incident ManagementSystem has all components to assist Incident Management.(?Keep in notes or in slide?)
8Design Plans Contract Let, Bid Awarded for $3.8 Million Construction Began March 2006Due to the complexity of the project, TDOT decided to select a firm to oversee construction, and selected Volkert and Associates Inc. to provide CE&I services.
9Considerations in Construction Site Selection FactorsView from CameraConstructabilityUtility ServiceFuture MaintenanceField changes may impact ideals of design.Example: South side of Chickamauga DamConsider the seasons when selecting a site, if the site is chosen in the winter when there is no foliage, keep in mind that when Spring comes around you will encounter increased vegetation.Utilities: limited power and communication service in remote areas. Advantage of using BellSouth.Maintenance example: Signal Mtn.
10Considerations in Construction Coordination with Other AgenciesCity of ChattanoogaTVAAvoid Conflicts Wherever PossibleCity: Electric permits and inspectionsTVA: Chickamauga Dam, Special provisions due to overhead power lines and archeological permit.Design avoided railroad conflicts.
11Considerations in Construction EquipmentTechnological AdvancesDiscontinued EquipmentFlexibility in Pole and Camera ConfigurationSome equipment may be obsolete by the time the construction phase begins.Some equipment may be hard to obtain because it is so new: field hardened equipment practically coming right off of the assembly line.Pole and Camera Configuration: Visibility- take into consideration obstacles in the line of sight of the cameras.
12Considerations in Construction Equipment (cont.)Compatibility of Communication ProtocolsTech Involvement with Specified EquipmentCommunication and coordination with techs involved in use of final product/spec’d equipment.Bring them into planning AS EARLY AS POSSIBLE
13Considerations in Construction Utility CoordinationSchedules for Placement & activationProvisions for Future Costs/Financial ProjectionsCurrent costs for communications alone are $20,000 per month.Electric costs are minimal. Each site has a meter.
14Considerations in Construction Adjacent Project ImpactEnvironmentalEPSC QA/QCStabilization of work site after poles and cameras have been installed, trenching.
15Considerations in Construction TMC CoordinationArchitectural CoordinationTMC Construction Contractor CoordinationDesign of TMC building was not included in scope of work for Prime Contractor, and was build by TDOT.
16FINAL STAGES OF PROJECT Conditional Acceptance: End of September6 month Burn In PeriodCamera images will be available to public through TDOT’s website
