Traffic monitoring is a means of counting and classifying vehicles and measuring vehicle flow characteristics, such as vehicle speed, lane occupancy, turning movements and other items typically used to portray traffic movement. In order for traffic monitoring data to be assessed properly, information on how the data were collected, edited, summarized and reported must be provided. This obligation…

A proposed new ASTM International standard will help consumer goods developers and manufacturers in the evaluation of their products to ensure product quality, consumer satisfaction and marketing success. The proposed standard, ASTM WK29225 , Guide for Design and Execution of Sensory-Instrumental Correlation Studies, is being developed by a task group of Subcommittee E18.03 on Sensory Theory and…

Since the appearance of the first California-type models around 1940, the profilograph has been a popular device used for quality control in the construction of pavements. Both roadway and airfield landing agencies have adopted roughness indexes computed from profilograph-derived measurements as a level of construction quality. Emerging high-speed inertial profilers can now quickly collect…

A proposed new standard being developed by ASTM International Committee E17 on Vehicle-Pavement Systems will be the first to describe how truth-in-data should be applied to traffic monitoring data collection, summarization and reporting. WK25280 , Practice for Highway Traffic Monitoring Truth-in-Data, is under the jurisdiction of Subcommittee E17.52 on Traffic Monitoring. Current traffic…

Being able to compile and interpret data on how traffic turns through an intersection could have an impact on future environmental and safety decisions regarding intersection geometry and traffic control. However, until recently no standard has existed to properly obtain and use this data. Now, ASTM International Committee E17 on Vehicle-Pavement Systems has approved E2667 , Practice for…

Many products can come in contact with drinking water during various stages of its treatment and delivery. This contact can have taste and odor implications that will be addressed in a proposed new ASTM International standard, WK21784 , Practice for Assessing Flavor of Drinking Water. Subcommittee E18.06 on Food and Beverage Evaluation, a part of ASTM International Committee E18 on Sensory…
