Alta was the prime consultant for this transformative, $850,000 effort, applying the nationally recognized Safe System Approach to rethink how the region prevents traffic deaths and serious injuries.
This project featured an extensive data analysis task. In addition to routine analyses like a High Injury Network, crash profiles, and a systemic safety analysis, Alta piloted new and innovative analyses. The cross-sectional database used AI-derived data from aerial imagery to build a database of the cross-section of every roadway in the region. This includes the number and types of lanes, and the presence and width of sidewalks, bike facilities, medians, and landscaping. The database was an important input into the layered network analysis, which identified modal priorities for every street in the region based on land use and roadway features, enabling the engineering team to recommend countermeasures most suitable for the context.
The team is examining the underlying causes of roadway incidents, identifying systemic risks, and working closely with local partners to understand how people actually move through their communities. By combining technical analysis with community insight, the plan will outline targeted, evidence-based interventions designed to create safer streets for everyone—whether traveling by car, on foot, by bike, or via transit.
This initiative represents a shared commitment to protecting lives, strengthening neighborhoods, and building a transportation network that supports a safer, healthier, and more connected future for Guilford County.
