NAME OF FIRM: PHONE: TAX PERMIT: UNSIGNED BIDS BUSINESS ADDRESS: CITY AND STATE. ZIP: WILL BE REJECTED AUTHORIZED SIGNATURE: TITLE: DATE. VideoTrak®-900 Video Vehicle Tracking and Detection System Technical Specification 2.0 This specification describes the physical and functional properties of a video vehicle tracking and detection system. The video tracking unit (VTU), only requires a computer/laptop interface for setup and query. 1.0 HARDWARE 1.01 Physical Dimensions The video tracking unit (VTU), has a 19" EIA chassis which may be rack or shelf mounted. Overall physical dimensions are 7"H x 19"W x 9.5"D (178x483x241mm). This chassis will accommodate up to 12 VME modules and a VME power supply. 1.02 Modules/Bus The VTU will utilize the VME (Versa Module Europe) bus. All modules will be 3U (160mm x 100mm) and will plug into the VME J1 connector on the bus. All modules will have slot ejectors. 1.03 Input Power The VTU will be powered by 120VAC/60Hz or 240VAC/50Hz with an automatic voltage sensing power supply. A typical 3 -wire •removable computer style plug will provide power to the unit. 1.04 Environmental The VTU will meet or exceed NEMA TS -1 and TS -2, as well as Type 170/179/2070 environmental specifications, and will operate between the ambient temperature range of -40C to +85C, 0 to 95% non -condensing humidity. 1.05 Operational Status Indicators The VTU will have Power On and SYSFAIL LED indicators for easy visual verification of unit operation. 1.06 RS -232 Communications The VTU will have two (2) RS -232 ports for serial communications up to 56.8K baud. Port C will interface via standard RJ -45 connectors. These ports can be used for communications to a modem, laptop, computer, controller, etc. Port "B" utilizes the ATMS (Advanced Traffic Management System) protocol to provide unsolicited data transfer via a user supplied program. VideoTrak®-900 Specification/ Rev. 26 Jan 1999 1 • • 1.07 RS -485 Communications The VTU will have a RS -485 port directly to a NEMA TS -2 controller or to a TS -2 BIU. 1.08 Input/Output Modules The VTU will accommodate up to 4 I/O modules. Each I/O module will be capable of 32 outputs and 16 inputs via a 'D' sub connector that will interface directly to cabinet terminals and facilities. I/O modules are available in either 12V or 24V configurations. 1.09 Detection Outputs Outputs can correspond to detectors or incidents. All outputs are •monitored by internal diagnostics for proper operation. 1.10 Cabinet Inputs Inputs can correspond to Phase Red and Green Status for detector functions and law enforcement, and other input functions as might be necessary. Video Input/Output The VTU can have up to 2 VPM's in operation for a total of 10 video inputs and 2 video outputs. 1.12 Video Connections Field video cables are terminated to lightning protection devices with BNC connectors on the VTU Interface Panel. From the Interface Panel, a micro -coax cable assembly allows clean, easy routing of the cable to the VTU, where the micro -coax cable interfaces via a single connector. 1.13 Video Indicators LED's on the VTU front panel indicate if the video signal is present and valid, and if the video picture is useable to provide quick verification of system status. VideoTrak®-900 Specification/ Rev. 26 Jan 1999 2 • • 2.0 VIDEO 2.01 Video Inputs The VTU will accept up to 8 video inputs for analysis and detection from video cameras or videotape players. Two (2) additional video inputs will be provided for routing the video from surveillance cameras. 2.02 Video Input Sources Video inputs can be either monochrome or color. RS -170 (monochrome), NTSC (color), CCIR (monochrome), and PAL (color) formats are accommodated. 2.03 Video Outputs Any of the ten 30 frame per second video inputs can be routed to the video outputs. These outputs provide real-time analog video, and do not require D/A (Digital to Analog) converters. 2.04 Digital Video The VTU can transmit digitized video, via serial communications, from any of the eight digitized video inputs. Built-in software CODECS (COmpress/DECompress) provide maximum frame rates for a given communication medium. 2.05 Viewing Video - Real-time VTU operation can be viewed utilizing the digitized images on a computer or laptop at some given frame rate (a function of the communication medium and computer speed), or in full motion 30 frame per second video. Analog video (30 fps) can be displayed on a computer with an appropriate digitizer board. Detection zone activity is indicated with highlighted detection zones when vehicles are present. 2.06 VCR Style Operation The Personal Interface Computer (PIC) provides a VCR type operation. When activated, the PIC will allow storage of digitized images. This video can be stored to some device such as a hard drive for later playback. • VideoTrak®-900 Specification/ Rev. 26 Jan 1999 3 3.0 TRACKING AND DETECTION 3.01 Tracking The VTU is a full Field of View tracking based system utilizing multi- resolution processing - therefore, detection is a by-product of tracking and is inherently accurate and robust. The VTU utilizes up to 5 tracking strips per Field of View (FOV) for tracking vehicles based on flow and direction. 3.02 Tracking Strips Tracking strips can be of any size and orientation within the FOV, and are typically associated with a lane, shoulder, or other areas of interest. Tracking strips define these interest areas and are comprised of 4 to 8 points making a polygon. Tracking strips are independent and can overlap and intersect. 3.03 Image Contrast Failsafe The VTU must have the capability to detect image contrast failures or poor quality video images from each camera. If the camera FOV does not contain a minimum amount of contrast, the VTU must go into a failsafe state. 3.04 Stabilization The VTU must be able to compensate for minor vibration or sway of the camera. Detection algorithms shall be designed to accommodate minor camera motion without the need for special hardware or programming. 3.05 Field of View Calibration The VTU has FOV calibration for accommodating perspective variations due to varying camera heights and angles. By defining 4 existing objects or points within the FOV and providing connecting distances in actual ground coordinates, the VTU will accurately adjust calculations for perspective. 3.06 Detection Zones The VTU can have up to 32 detection zones per camera FOV, for a total of 256 zones per unit (8 camera detection unit). A detection zone consists of a line or polygon of any size and orientation drawn on a video image. This line can consist of up to 4 points within or across any tracking strips. Detection zones can overlap and intersect and can span multiple tracking strips. 3.07 Detector Types Statistics Detection zones can be programmed as detectors or for incident monitoring. All zones are capable of traffic data collection. Special detector types are not required. VideoTrak®-900 Specification/ Rev. 26 Jan 1999 4 3.08 Statistics Each detection zone can log the following statistics: • Volume/counts (# of vehicles) • Lane Occupancy (% time lane is occupied) • Speed (average speed in mph or kph) • Density (average density = volume/speed) • Headway (average headway in seconds) • Length (average vehicle length in ft/meters) • Vehicle Classification by user -selectable lengths (5 bins) • Delay (average delay in seconds) • Queue Length This data can be stored in a selectable time period of 10 seconds, 20 seconds, 30 seconds, 1, 5, 10, 15, 30 or 60 minutes. This data is available via RS -232 in real-time and may also be stored in FEPROM for any zone. RS -232 real-time statistics can be retrieved via ATMS protocol defined under ATMS protocol section of the specification. All zones can have statistics stored in FEPROM; the number of zones selected for storage and time slice will determine the maximum storage time (days, weeks). 3.09 Incidents In addition to the detection zone statistics, any of the camera's 32 detection zones can be configured for automatic incident detection and output. Incident detection zones can monitor any of the following incidents: • Vehicle presence for 'n' minutes or seconds • Vehicle speed (under speed, over speed, or speed within specific range) • Wrong way detection • Queue Length exceeded • Delay exceeded • Occupancy exceeded (low occupancy, high occupancy, or within a specific range) • Red traffic signal runners For some incidents, the user must have the option to select whether incident zone activation is based upon "individual vehicle" data or "period average" data. Incidents based on "individual vehicle" data will trigger any time that a single vehicle meets the incident criteria. Incidents based on "period average" data will trigger any time that data gathered over the statistics time slice meets the incident criteria. For instance, this option may be used to trigger speed incidents based upon either individual vehicle speed or average vehicle speeds over the programmed statistics time slice. All incident detectors shall have the ability to both tum on an output and also log the incident. VideoTrak®-900 Specification/ Rev. 26 Jan 1999 5 • • 3.10 Output Assignments Detection zones can be assigned to any combination of outputs, independent of logging and reporting capabilities. More than one zone can be assigned to an output with the use of a logical operator. Selections must include OR, AND, NOR and NAND. The default operator shall be OR. 3.11 Detector Types A detector can simply operate as a presence detector; however, there are several additional detector types and options that may be programmed for a detector. The various types of detector operations are described below. Detect Always This option is the default state of all "detector" type detection zones. It should be selected if simple presence detector functionality is desired. When a vehicle enters a zone, it will activate immediately and remain active for the entire time that the vehicle is present. When the vehicle leaves the zone, the zone will immediately de -activate. This operation requires no phase associations or constraints Conditional Detector This option makes detector operation conditional upon an associated phase state (Red, Yellow, or Green). With a conditional phase association, the detector will only report detections while the assigned phase (input) is active. For more accurate turning movement counts, a detection zone can be placed well into an intersection but be programmed to activate and count only when an associated phase is green. This feature also allows users to design dilemma zones, etc. by disabling or enabling detectors based on phase status. Extend / Delay Detectors may be programmed to Extend or Delay activation and any associated output. An entry field shall be provided that allows the user to define a time period (in seconds) that the detection zone activation will be either extended or delayed. The Extend function forces a zone to remain active for a user defined time period after the last vehicle has exited the zone. The maximum extend time is 25.5 seconds. This operation may be associated to a particular phase. The Delay function forces a zone to remain inactive for a user defined time period after a vehicle enters and remains in the zone. If the vehicle remains in the zone, it will activate once the programmed delay time has elapsed. The maximum delay time is 30 seconds. This operation may be associated to a particular phase state. VideoTrak®-900 Specification/ Rev. 26 Jan 1999 6 • 3.12 Occlusion Compensation A feature must be available to allow improved multi -lane freeway count accuracy when using less than ideal camera locations. Occlusion Compensation operates on the premise that adjacent lane over counting on multi -lane freeways is often due to occlusion by large vehicles (tractor trailers, buses, and other large trucks). These vehicles visually appear to occupy the adjacent lane away from the camera. Assuming that these vehicles are usually long, as well as tall, the adjacent lane detector can be de -activated while the truck is occluding the adjacent lane. Without occlusion compensation, both detectors would count the truck. With occlusion compensation, the detector covering the lane on the far side of the truck is deactivated and does not count (or provide an associated output) until the truck exits the detector in its own lane 3.13 Camera Mounting The system shall optimally detect vehicle presence when the camera is mounted 30 feet (10 meters) or higher above the roadway, when the camera is adjacent to the desired coverage area, and when the length of the field of view is not greater than ten (10) times the mounting height of the camera. Cameras should be mounted as close as possible to the center of the traffic lanes to be viewed, to diminish the effects of cross lane, adjacent lane and same lane occlusion. 3.14 Per Vehicle Records (Academia Mode) A Per Vehicle record program shall be available. It shall be a DOS based program that allows access to actual "per vehicle records" (PVR's) for a specified camera. At each request (as fast as the PC can request data up to 57600 baud), the VTU sends back information for every vehicle being tracked within the specified field of view. Information returned includes vehicle ID, time tracked, current X -Y coordinates, length, speed and uncertainties, as well as several other parameters. The data is stored as rapidly as possible into a binary file, and then converted into a comma delimited ASCII file upon termination of the program. A spreadsheet, word processor or custom application can then analyze this file. 3.15 Detection Accuracy Using a camera mounted as defined in section 5 and in the location as defined in section 3.13, the system shall be able to count vehicles with less than four (4) percent error rate under normal conditions and less than seven (7) percent error rate under artifact conditions caused by shadows, fog, rain, and snow. The volume count shall be for the entire field of view and shall be compiled over time intervals, which contain a minimum of 100 vehicles to ensure statistical. significance. VideoTrak®-900 Specification/ Rev. 26 Jan 1999 7 • 3.16 Two Independent Configurations The database for each VTU shall contain two complete and independent configuration settings. These configurations are referred to as either Config #1 or Config #2. Each database contains a complete set of strip and zone layouts, tracking parameters, and calibration points for each Field of View. Each configuration also contains its own unique output assignment information. In some cases, it is desired to switch between these two configurations to perform certain advanced functions. For instance, in applications where lanes may be reversed during certain periods, the user may desire to change the placement and function of detection or incident zones accordingly. To accomplish this, the user may select to change configurations based upon Time of Day, Input, Output, or Zone State. Switching by Time of Day At the specified T.O.D., the VTU will automatically switch to the Config #2 settings. Switching by Input To implement an input must be selected and also defined as to the desired state of ON or OFF when active. When the specified input is in the programmed state, the VTU will automatically switch to the Config #2 settings. Switching by Output To implement an output must be selected and also defined as to the desired state of ON or OFF when active. When the specified output is in the programmed state, the VTU will automatically switch to the Config #2 settings. Switching by Zone To implement, select the desired state of the zone by selecting either ON or OFF in the selection box provided. When the specified zone is in the programmed state, the field unit will automatically switch to the Config #2 settings. 4.0 PERSONAL INTERFACE COMPUTER (PIC) 4.01 Computer interconnection A Personal Computer Interface (PIC) provides a user-friendly interface to the VTU via an RS -232 connection. 4.02 Computer Requirements The PIC can be any desktop, portable or laptop computer that is running, Windows 95, or Windows 98. The PIC should be a Pentium or higher with 16M RAM and a 50M available on the hard drive. A 16550 UART, standard on all new computers, is required for serial communications. VideoTrak®-900 Specification/ Rev. 26 Jan 1999 8 • 4.03 User Interface The PIC will run the Windows TM' program for programming and interfacing to the VTU. This Windows M program will enable setup and programming for the VTU and provide the interface for real-time viewing and operations. 4.04 System Configuration The PIC will be used, in conjunction with a mouse or other pointing device, to draw and configure tracking strips, detection zones, and other features required for configuration and setup of the VTU. Live digital video, a single digitized frame, or live analog video with a custom digitizer card of the actual camera FOV may be utilized in this setup. 4.05 System Monitoring The PIC will be used for watching real-time operation of any camera, by utilizing compressed digital video transmitted via a serial communication link. Multiple VTU's and multiple cameras can be viewed in different windows. Detection zone activity, as well as incidents, will be highlighted and indicated on the VGA display of the PIC as traffic moves through the scene. 4.06 Digital Movies The PIC will be used for capturing and storing digitized video for later playback, in essence providing a VCR type recording mechanism for storing critical events. 4.07 Database and Addressing The PIC will be used for programming and storing all parameters required for operation of the VTU. In addition, the PIC can upload or download any of this data in user selectable portions. All VTU s will be completely addressable. 4.08 Statistics The PIC will be used for storage of traffic statistics. This data can be manually retrieved. All data will be stored in binary files to conserve disk space, with the capability of converting to other popular formats such as ASCII for use in spreadsheets, etc. The Windows"" program will contain several built-in graphs, charts and reports for presentation of the statistics. 4.09 Security There shall be at least 2 levels of security in the VTU field unit: Read/Write and Read Only access.
