Abstract:Transportation agencies are often faced with questions from communities concerning the safety and aesthetics of off/on ramps and intersections located below aging and unsightly interstate overpasses in the many rural-to-rapidly-urbanizing areas in Arkansas. A key issue is the challenges encountered by the citizens in their attempts to implement economic development projects, a crucial need for the Arkansas Delta. These challenges are routinely intertwined with those facing the Arkansas Highway and Transportation Department (AHTD) because communities and citizens have substantive issues but may not understand AHTD technical and regulatory needs and constraints. The project studied the feasibility of interstate bridge and intersection design solutions—including roundabout feasibility —and developed a model for community-based transportation planning that can facilitate the interface between community stakeholders and the agencies implementing infrastructure modifications. Phase 1 included analysis and presentation (for community and agency approval) of formal design options for the I-40/I-55 bridge intersection with state Highway 77 in West Memphis, Arkansas, to advance transportation efficiency, public safety, and visual enhancement as a response to increasing population growth and economic development in the area. Phase 2 focused on development and documentation of a community based expert-system planning model that could be used to address similar transportation issues throughout the Arkansas Delta and beyond.
