Monograph

This issue contains 16 papers concerned with urban and traffic data systems. Specific topics addressed are as follows: vehicle length measurement and length-based vehicle classification in congested freeway traffic; vehicle detector evaluation based on concepts of traceability and confidence intervals; a hybrid prediction approach based on weekly similarities of traffic flow for different temporal scales; the identification of network sensor locations for estimation of traffic flow; and an algorithm for detector-error screening on the basis of temporal and spatial information. Other topics addressed in this issue include a process to determine locations for motorcycle counts; software-based vehicle reidentification with existing loop infrastructure; the effect of traffic load input level on mechanistic-empirical pavement design; bias in traffic data aggregation resulting from transition of traffic states; a semiautomated tool for extraction of microlevel traffic data from videographic surveys; and reidentification of trucks on the basis of axle-spacing measurements to facilitate analysis of weigh-in-motion accuracy. In addition, the issue addresses the estimation of annual average daily bicycle traffic with adjustment factors; estimation of spatially and temporally continuous bicycle volumes by using sparse data; an automated analysis of pedestrians’ nonconforming behavior and data collection at an urban crossing; institutionalizing bicycle and pedestrian monitoring programs in three states; and the application of seasonal adjustment factors to subsequent year data.
