A Computational Vision Model-based Method to Address Work Zone Conspicuity

A computational means to assess the conspicuity of highway features was developed, verified, then applied to a sample construction work zone scene. This work was conceived as a balance between modeling the complex phenomena within the human visual system and the need for a simple applications oriented tool for practitioners to derive a quantitative relative assessment of real world construction work zones in order to rank choices in terms of conspicuity. The results indicate that our vision model-based tool can assess the relative conspicuity of individual elements of a roadway or roadside scene and is relatively straightforward in use. As such, it holds potential value in engaging in “virtual” prototyping of work zone sight lines, colors, and placement of hazard warning cues such as cones, markings and reflective vests.
