The FHWA has purchased the van and will be delivered to the vendor for installation of the equipment. The vendor shall offset the cost of the equipment with the Fair Market Value of the FHWA's current data collection vehicle (ARAN 4900 by Roadware). II. Equipment Installation on Data Collection Vehicle 1.0 On Board Equipment 1.1 Rut Depth Measurement Sensor. The rut bar shall consist of five laser sensors. One sensor shall be mounted above each wheelpath and may also serve as the sensor for the roughness system. A third laser sensor shall be mounted in the center of the rut bar. Two additional laser sensors shall be mounted to either side on the end of the rut bar. These shall point outwards 18 inches on either side of the rut bar. These sensors shall not extend beyond the normal width of the vehicle and its original bumper. The rut depth system shall include sensors to correct for vehicle attitude to accurately measure cross fall (cross slope). These sensors must be integrated with an on-board gyro systemto provide network survey level precision data to measure the true transverse slope of the road on straight sections (cross fall) as well as on curves (super elevation). 1.2 Roughness Measurement Sensor. Longitudinal Profile measurement system shall use laser/accelerometer sensors in each wheelpath to provide profile data with which to calculate ride indices. The system shall be of the type designated as a South Dakota Profiler and capable of calculating IRI in real time. The units of measurement shall be operator selectable in either inches per mile or meters per kilometer. The system shall measure roughness at speeds between 15 mph and 65 mph with better than 5% bias. The software shall calculate a Ride Number and IRI (International Roughness Index) in real-time. The system shall meet the definition of an ASTM Class I profiler and of the FHWA Class II profiler as defined in the HPMS (Highway Performance Monitoring System) Field Manual. After the data is processed, the profiles must show variations in slope as they affect roughness. The processing software must exclude the static elevation and slope of the roadway itself so as not to affect the validity of the data. The system shall collect and store profile measurement data at selected longitudinal distance intervals. Data samples for roughness shall be collected at 12.5 mm (0.5 in) intervals at speeds between 12.5 mph to 65 mph. Resolution shall be 0.1 mm. Profile shall be calculated for wavelengths from 0.5 foot to 1000 feet. IRI shall be calculated and displayed in real time at operator selected intervals from 0.05 miles to 1.0 miles. The standard deviation of repeat tests of the profiler shall be within +/- 5% of the mean IRI value on each test site. The accuracy of the profiler shall be within +/- 5% on specified test sections with a Face Dipstick or other HPMS Class I device. 1.3 Distance Measuring Instrument DMI. The DMI shall be a precision optical encoder mounted on the rear axle of the vehicle. It shall measure a minimum of 2000 pulses per wheel revolution to provide a resolution of 1.33 mm The accuracy shall be 0.02% of the distance traveled. 1.4 Global Positioning System (GPS) with differential correction. A Global Positioning System must be provided. The mobile GPS receiver shall be a Trimble AGM132, integrated 12-channel receiver/dual-channel MF differential beacon or equivalent. The receiver shall be RTCM-10 compatible. The GPS data shall be correlated to other sensor data via DMI chainage. The modularity of the GPS system shall allow for upgrades to either post processed differential GPS (DGPS) or real time DGPS provided by Omnistar (or equivalent). An inertial measurement unit (gyros) shall be provided for GPS fill-in in the event that the GPS signal is lost. 1.5 Inertial Measurement Unit (IMU). An inertial measurement unit must be provided. This system must integrate with the GPS system to fill in for loss of GPS signal. The IMU must also integrate with the rut bar data to calculate correct super elevation and cross slope. The unit must be solid state device such as a ring laser gyro or fiber optic gyro with a heading accuracy of at least +/- 0.5 degrees, and roll/pitch accuracy of +/- 0.05 degrees. A spinning mass gyro or flux gate compass is not acceptable. 1.6 Digital Perspective Video. One high resolution, progressive scan video camera, (1300x1030 pixel) shall be provided to record mid-point right of way features. The camera shall record directly to digital disk with no intermediate videotape devices. Two additional high resolution, progressive scan video cameras (1300x1030 pixel) shall be provided to record the left and right features of the right of way. These cameras shall also record directly to digital disk. The video cameras shall be mounted in a weatherproof enclosure that permits easy access for service and adjustment. The perspective video system shall be capable of recording images at 10 foot intervals regardless of the speed of the vehicle. The images shall be recorded in JPG format and compressed to between 50 KBytes and 100 KBytes selectable by the operator. Each image shall be tagged with a unique identifier to permit retrieving images with other survey data including linear distance and GPS location. The central perspective view images shall display header information such as Route, date, linear distance and frame number plus other data entered by the operator. The header information shall not intrude on the picture or cover any features in the image. The video server computer for all three cameras plus digital pavement cameras must be capable of storing up to 1,000 miles of images before downloading. A high speed digital linear tape or removable hard drives must be provided for transfer of images to an office workstation. 1.7 Digital Pavement Video. Two high resolution, progressive scan video cameras shall record pavement images. These cameras shall record directly to digital disk with no intermediate videotape devices. The images shall be automatically joined, left and right, and longitudinally to create a continuous view of the pavement. The images shall be tagged with a unique identifier to permit retrieving images with other survey data including perspective view images and linear distance and GPS location. Artificial strobe lighting shall be provided to reduce or eliminate shadows from overhead objects. 1.8 Central Control Computer. An on-board Central Control Computer shall be provided to record sensor data and to interface with gyro system, GPS, DMI, and other on-board sensors.
