SPR-5133: Evaluation of In-CAB Virtual Sign Network on CMV Safety and Operations

Construction work zones often have reductions in lane widths, reductions in shoulder widths, soft shoulders, and uneven pavement profiles that can present challenges for Class 9 vehicles. Although roadside signs can be used, it is believed that targeted incab alerts can perhaps be more effective at alerting commercial drivers of these issues and improve safety.
