TRB’s Transportation Research Record: Journal of the Transportation Research Board, No. 2105 includes 17 papers that explore passive transit travel surveys; improving the usability of a complex household travel survey; harmonization of long-distance travel demand figures for European countries; Global Positioning System (GPS) raw data processing without additional information; a semidirective interview method to analyze travel behavior changes; cell phone samples in transportation surveys; household travel surveys with GPS; and suppressed travel measurement and estimation using enhanced activity-travel diaries. This issue of the TRR also examines household travel data synthesis using model-based approaches in small and midsize metropolitan areas; geolocation data compression for transportation target identification; using GIS in a public involvement context to assess transportation infrastructure of most relevance to livable communities; transport and surveillance aspects of location-based services; spatial interpolation of traffic counts; vehicle detection from satellite images; online travel time prediction using Bayesian training and committees of state-space neural networks; a distributed algorithm for estimating dynamic origin-destination demand; and a kinematic terrestrial light-detection and ranging (LIDAR) system for scanning.
