20 Flag Assessment for Multimodal Safety at Faulkland Road and Centre Road, Wilmington, DE

This presentation will show how the new 20 Flags Assessment for Pedestrian and Bicycle Safety was used to evaluate and conceptually redesign Centre Road and Faulkland Road intersection in Wilmington, Delaware. Two redesigns were created — one involving low-cost strategies and the other a more comprehensive adjustment of the traffic control.

A Five-Leg Protected Intersection: Opportunities and Challenges

The five-leg intersection of Cleveland Avenue, Paper Mill Road, Chapel Street, and Margaret Street in Newark, Delaware has been a capacity and safety challenge for decades. While a recent project helped to address capacity issues, there are still multimodal safety concerns at this location. This presentation will frame those concerns in the context of the community, describe walking and bicycling networks in the area, and propose an unconventional type of protected intersection to reduce conflicts among all modes of travel.
