| Abstract | Traffic data collection is a vital part of the Strategic Highway Research Program's (SHRP) Long Term Pavement Performance Project (LTPP), of which the Arizona Department of Transportation is an active participant. The accurate monitoring and evaluation of traffic data, particularly along test sections (Specific Pavement Studies and General Pavement Studies) ensures that these studies are based on reliable traffic characteristics. this is an important parameter for the validity of study results and conclusions. According to the "Framework for Traffic Data Collection for the General Pavement Studies Test Sections" released by the Strategic Highway Research Program in january 1989, the Long Term Pavement Performance Program has six specific objectives, which are: (1). Evaluate existing design methods (2). Develop improved design methodologies and strategies for the rehabilitation of existing pavements. (3). Develop improved design equations for new and reconstructed pavements. (4). Determine the effects of loading, environment, material properties and variability, construction quality, and maintenance levels on pavement sdistress and performance. (5). Determine the effects of specific design features on pavement performance. (6). Establish a long term national data base to support SHRP's objectives and future needs. This report presents a summary of vehicle count, classification, and weight data collection and monitoring effort at the initial 27 program sites around the state of Arizona, most of which were installed in October/November 1992. It highlights procedures taken to identify performance shifts, calibration of equipment, and on-going efforts to upgrade and expand the data collection program. |
