3 ARAN Capability Summary Roughness Longitudinal Profile Faulting Texture Rutting Cross Slope Transverse Profile WiseCrax VisiData Curve and Grade Differential GPS Right-of-Way - High Resolution Digital Video Strobed Pavement Video Surveyor POS/LV Laserlux

4 ARAN-Automatic Road Analyzer Proven Multi-function Highway speeds Single Pass Modular

5 Roadware Technology History Founded in 1969 Technology Leader – 1980 ARAN proto-type – 1984 1st production ARAN – 1993 3rd generation ARAN – 1994 Surveyor – 1994 WiseCrax - Automated Distress – 1996 POS/LV Inertial Measurement Unit – 1997 WiseCrax/NT - 2nd generation – 1998 VisiData - Data Visualization Tool – 1999 Ultra Hi-Res Digital Video Modular Design Benefit: Protects Investment from Obsolescence

6 Roadware Experience 100+ employees – 85% technical staff Over 70 ARANs in 20 Countries – ARAN used by 25 States & FHWA Roadware operates 8 ARANs – Over 100,000 miles under contract Benefit: Experienced Qualified Support

11 Video Analog Video – Continuous or Sampled Multiple camera configurations – Panoramic – Side view – Guide rail – Rear view Digital Video –High Resolution –Ultra High Resolution

12 Right-of-Way Video High Resolution Digital - Full-frame Continuous or Sampled Multiple camera configurations – Panoramic – Side view – Guide rail – Rear view

25 Videotape to Digital +Acceptable Quality +Economical +Continuous 30 fps => 3 foot interval -3 to 6 hours time to digitize 60 miles -Hundreds of tapes to archive -Limited resolution

26 Direct to Digital +Not limited to 640 x 480 pixels +No additional time to convert +Sharper images -High Storage Requirements -Longer intervals between images

27 Videotape to Digital

28 Direct to Digital

29 Direct to Digital vs. Videotape to Digital

30 Conclusion Direct to digital is clearly superior IF You can afford the storage

31 Digital Storage Requirements High Res 640 x 480 = 900 Kbytes/image Mega Pixel 1300 x 1030 = 4 Mbytes/image

32 Image Compression High Res 640 x 480 = 900 Kbytes/image @ 20:1 = 45 KB Mega Pixel 1300 x 1030 = 4 Mbytes/image @ 20:1 = 200 KB @ 40:1 = 100 KB

33 High Res Uncompressed vs. Compressed

34 Size Comparison

35 Mega Pixel Uncompressed vs. Compressed

36 Storage Systems Analog Video Tape Tape = 100 miles 10,000 miles = 100 tapes Disc Removable = 20 GB = 4,000 miles DVD = 4.7GB = 940 miles CD ROM = 650 MB = 130 miles Digital Linear Tape DLT = 70 GB = 14,000 miles

37 Conclusions Compression rates have little effect on quality at 20:1 to 40:1 Major advantage of high resolution is the ability to zoom in on details Storage is feasible Digital is superior

38 VisiData-Visual Data Presentation Roadway data at your finger tips – Video – Hierarchical Tables – Charts Drive the network; review data concurrently Easy to use desktop application

39 Right-of-Way View of selected section Tool bar with play buttons to “drive” the road Data Grids to show tabular information such as location and numeric values Graphical charts display data to identify specific sections with out-of-limit values SQL Query capability to include or exclude data within specified limits such as to display roughness exceeding 200 in/mi
