N2  - Most current methods used to estimate vehicular delay at intersections involve some form of manual data collection. These methods rely on statistical techniques (such as multiple linear regression) to improve the accuracy of the delay estimates. In addition, most require significant data collection and reduction efforts. The theory, design, operation, and evaluation of a microprocessor-based system for the collection of vehicular delay data at intersections is presented. The principle of the automated system, including definitions of pertinent variables and equations, is discussed. An overview of the system design, including a description of the vehicle detection scheme and the microprocessor's recognition of vehicle arrivals and departures, is presented. There is a discussion of the system software as well as a description of the data collection and reduction processes. The system performance was evaluated both in the laboratory and through analysis of data collected in the field. Recommendations for further development of the device are presented.<p /> <p>Language: en</p>
