Analyzing Residential Speeding Using Connected Vehicle Data: A Case Study in the Charlottesville, VA Area

Abstract

This study uses connected vehicle data to analyze speeding behavior on residential roads. A scalable pipeline processes trajectory data and supplements missing speed limits to generate summaries at OpenStreetMap’s way ID level. The findings reveal a highly skewed distribution of both aggressive and reckless speeding. Based on a case study of Charlottesville, VA’s connected vehicle data on residential roads, 38% of segments had at least one instance of aggressive speeding, and 20% had at least one instance of reckless speeding. In addition, the point-based nighttime speeding rates were higher than daytime rates for the vast majority of residential segments, and extreme violations on specific road segments highlight how severe the issue can be. Several segments rank among the top 10 for both aggressive and reckless speeding incidents, indicating particularly high-risk residential roads. These findings support the need for both spatial and behavioral interventions. This study provides a rich foundation for policy and planning, offering a valuable complement to traditional enforcement and planning tools. In conclusion, this framework sets the foundation for future applications in traffic safety analytics, demonstrating the growing potential of telematics data to inform safer, more livable communities.
