PURPOSE
The purpose of this study was to identify options and costs to calm traffic along Griffin View Drive, identify potential roadway improvements along Griffin View Drive at the intersection with Harbor Hills Boulevard and identify possible intersection modifications to improve safety and increase sight distances along Griffin View Drive.
EXISTING CONDITIONS• Posted Speed 35 MPH• Limited Right of Way• 8% and 10% Profile Grade
BACKGROUND DATA• 215 Trips Griffin View Drive – EAST• 1,000 Trips Griffin View Drive – WEST• 85% Speed – 46 MPH• 8% of trips 50 MPH• NO CRASHES reported 1/1/2000 through 3/1/2010
DESIGN ALTERNATIVES
1. Three-Way Stop Condition with Rumble Strips2. Curb Section with addition of dedicated East Bound Left
Turn Lane3. Re-alignment of Vertical Curve for 40 MPH design speed4. Re-alignment of Vertical Curve for 45 MPH design speed5. Re-alignment of the intersection horizontal geometry6. Addition of an Acceleration Lane for drivers exiting Harbor
Hills west bound on Griffin View Drive7. Addition of Speed Humps8. Intersection modification with Roundabout installation
EVALUATION
• ALTERNATE 1–Least Expensive–Easiest to Implement–No Right of Way Required–Wheel noise from rumble strips–Danger of cars running stop sign
EVALUATION
• ALTERNATE 3–Addresses Site Distance Issue–An Expensive Option–Requires Additional Right of Way–Grading Easement–Does not reduce speeds on Griffin
View Drive
EVALUATION
• ALTERNATE 5–Provides Traffic Calming–It is a Median Pricing Alternative–Requires Some Right of Way – Only
from Harbor Hills
