TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 1993 includes 22 papers that explore revenue risk mitigation in transportation project financing, traffic sign asset management, estimating highway investment requirements, estimating design hourly volumes, traffic prediction, digital dashboards, random count site selection, wireless location technology-based traffic monitoring, traffic flow impact on travel time variability, and transferability of National Household Travel Survey data. This issue of the TRR also examines the impact of nonresponse and weighting in a travel survey, data integration impact on travel behavior indicators, iterative proportional fitting algorithm for combining traffic count data with missing dimensions, an electronic freight theft management system using Internet-based mapping, and regional routing model for strategic waterway analysis. It also reviews the Highway Capacity Manual adjustment factor for annual weekday to annual average daily traffic, automated consensus-based data verification, enhancing truck data accuracy using dual-loop event data, video-based vehicle detection and classification system, gross vehicle weight distributions from weigh-in-motion data, detection and tracking of vehicle base fronts for traffic counts and speeds, and customizing quality assessment techniques for traffic data archives.
