Transit Impacts on Jobs, People and Real Estate, from the University of Arizona, represents the culmination of nearly a decade of research into the economic effects of transit. To unpack the dense and substantial findings from 17 LRT, 14 BRT, 9 SCT, and 12 CRT systems in 35 metro areas across the United States, the final report is split into five volumes. Arthur C. Nelson and fellow researchers Robert Hibberd, Kristina Currans and Nicole Iroz-Elardo of UA have completed the final phase of res...

Both crash frequency analysis (CFA) and real-time crash prediction models (RTCPMs) typically divide a highway into segments with a constant length for data aggregation. Despite the significant impact of the segment length in several previous traffic safety studies, no standard approach exists for determining a recommended segment length for crash data aggregation. This research investigates the impact of fragment size (segment length) on traffic crash data aggregation and establishes a method...
