Developing a Clustering-Based Empirical Bayes Analysis Method for Hotspot Identification
Hotspot identification (HSID) is a critical part of network-wide safety evaluation. Put simply, HSID involves ranking sites (e.g., roadway segments or intersections) on the basis of observed and/or estimated safety so they may be prioritized for treatment. Typical methods for ranking sites are often rooted in use of the ...
Freeway Traffic Safety And Efficiency Enhancement Through Adaptive Roadway Lighting And Control Enabled By Connected Infrastructure Networks
Visibility of the roadway and roadside objects often decreases as light (from natural and artificial sources) diminishes under a certain level. Roadway lighting, when used appropriately for the given context and conditions, can be an effective means for increasing visibility; however, inappropriate lighting can lead to issues ...
