• Abstract:
  "The Wyoming DOT has an interest in collecting automated data on pavement shoulders. Such data would include shoulder width, ; type, as well as slope. Pathway Services Inc. has been collecting Pavement Management Systems (PMS) data on roadways in Wyoming, ; and indicated they had the ability to measure the transverse profile of 10 to 20 feet from the white strip shoulder marking. Pathway Services ; has offered to provide measurements on test sections in Wyoming since they had not collected such data for any other states, so it was ; important to them to determine the limitations or potential of the system. ; The test sections included seventy miles of Wyoming highways with shoulder widths varying from zero to ten feet in two foot increments. ; Vegetation observations were made by researchers from the Wyoming T2-LTAP Center on the same day when Pathway’s data was ; collected to ensure identical conditions. ; It was found that the section with no shoulder had the most vegetation and the most varied slope measurements. It was concluded that ; vegetation does affect the accuracy of the sensor and that the sensor could not read past the pavement taper. In addition, the manually ; collected slope measurements and the automated slope measurements were statistically different on most of the sections included in the ; experiment."
