Abstract:

Work zones along interstates often have increased congestion and crash rates when locations are close to or over capacity. Having agile monitoring methods to identifying emerging issues and challenges can provide data to transportation agency decision makers to refine maintenance of traffic plans and inform future designs. This study developed techniques to fuse a multitude of data sources including connected vehicle speeds, connected vehicle hard-braking events, crash reports, digital alerts, commercial vehicle dash camera images, into a weekly interstate work zone report that gives stakeholders a holistic overview of their work zone operations and allowed for easy identification of opportunities for improvement. Approximately 249 weekly work zone reports were generated and distributed to approximately 100 stakeholders across the state on an approximately weekly basis. These reports provide an at-a-glance view of statewide, district, and route mobility, crash data, hard-braking, and most recently dash camera images to contextualize the heatmaps.
