FHWA’s Localized Bottleneck Reduction Initiative (LBR) program focuses attention on mitigating the operational causes of recurring congestion “hot spots” (i.e., traffic bottlenecks) at ramps, merges, lane drops, intersections, weaves, etc. One of the efforts of the LBR program is to encourage age
The primary objective of this research was to identify significant environmental (i.e., weather) variables that may contribute to snow and ice buildup on LED traffic signal lenses. If a subset of variables can be identified that may predict the potential occurrence of snow and/or ice buildup on L
Traffic incident management (TIM) is a planned and coordinated program to detect and remove incidents and restore traffic capacity as safely and as quickly as possible. Over time, various tools and strategies have been developed and implemented in an effort to improve overall TIM efforts. The nat
