TRAFFIC & SAFETY

Traffic

Traffic Volumes and Level of Service (LOS)

• Average Daily Traffic (ADT) for both U.S. 1 and Route 352 is projected to exceed roadway capacity
• Regional traffic growth factor was utilized to arrive at design year traffic volumes
• Design Year LOS for weekday morning (AM), weekday afternoon (PM), and Saturday peak hours for each intersection for both alternatives provided on a single board
• DVRPC’s regional traffic simulation model will be utilized to fine-tune the design year traffic projections for the no-build and build conditions using a selected alternative for each area during the next phase of the design
• Traffic analysis will be updated based on DVRPC’s traffic projections

Engineering Criteria 

• Both alternatives meet purpose and need
• Each alternative provides improved traffic operations compared to the existing conditions
• All existing traffic signals will be upgraded and interconnected
• Sidewalks will be added for pedestrian accommodation
• Predictive crash and travel time/delay analyses were performed for each alternative
• Alternative B for Area 1 requires additional structures, has higher complexity to construct, and one of the ramps will have over 8% slope
