Replacement of Pavement Evaluation Equipment
| 项目名称： | Replacement of Pavement Evaluation Equipment |
| 摘要： | Roadway evaluation equipment presently in use at the South Dakota Department of Transportation (SDDOT) employs instrumentation, video cameras, computer hardware and software, and exacting survey procedures to acquire data ultimately used in various analysis of roadways. In combination, the equipment collects video images, roadway profile data, roughness measurements, pavement distress, and faulting values. The collected data is referenced spatially through inherent GPS capabilities, and also linearly to roadway centerlines using the SDDOT Mileage Reference Marker (MRM) system. Technological advancements coupled with the need to continuously seek ways to improve operations often render data collection equipment, computer hardware and software, and survey procedures to become outdated after a certain time. Also, systems that receive the data often undergo upgrades and transitions that tend to make the data collection systems obsolete. Pavement Management Systems (PMS), computer operating systems, and video log viewing software are just a few examples of "receiving" systems that might be upgraded and thereby force corresponding changes to roadway data collection processes. The SDDOT Office of Transportation Inventory Management's vehicle and corresponding equipment are now five years old. Because technology has changed over that time and the vehicle currently has 80,000 miles on it, the SDDOT will soon need to consider either replacement, or else renovation of the existing equipment. A needs assessment will be essential to the decisions on the most appropriate configuration of the roadway evaluation equipment. Determining the needs will help define the configuration's functional requirements and the ultimate system specification. Once acquired, the roadway evaluation equipment will need to be validated through a pre-defined testing process that will ensure integrity of the operations, technology, and use for several years. The objectives of this research project are to: (1) Identify the SDDOT needs for roadway evaluation equipment through assessments internal to the Department, reviews of similar equipment presently in use at other states and Canadian provinces, and appraisals of newly emerging equipment and technology. (2) Develop a specification for an optimum roadway evaluation equipment configuration that is based on departmental needs and functional requirements, and also includes equipment testing criteria that can be used to validate performance before final acceptance. (3) Validate the roadway evaluation equipment performance over a timeframe appropriate to the system configuration ultimately approved so that the SDDOT can ensure integrity of the intended use well into the future. |
