SUBJECT/RECOMMENDATION:
Title
Provide direction on the recommended deployment of a one-way pair roadway system with Coronado Drive and Hamden Drive in the fall of 2016.
Body
SUMMARY:
The Traffic Operations Division has performed a modeling analysis using traffic counts at various intersections along Coronado Drive and Hamden Drive. These traffic counts have been entered into modeling software based on the Highway Capacity Manual/Synchro and other traffic engineering guidelines.
The analysis and modeling presentation which is part of this item was conducted to determine the operation impacts of making Coronado Drive one-way southbound and Hamden Drive one-way northbound on Clearwater Beach.
Some operational issues and impacts would be as follows: Coronado’s Volume would change from 10950 vehicles per day to 6380 vehicles per day due to the shift of northbound traffic to Hamden and the shift of southbound traffic from Hamden. Hamden’s Volume would change from 1210 vehicles per day to 5560 vehicles per day due to the shift of northbound traffic from Coronado and the shift of southbound traffic to Coronado. Traffic leaving the parking garages on Coronado would be required to turn right out of the garages and either access Fifth Street or Brightwater Drive to go north.
Under this proposal the conversion to one way on Coronado would occur at First Street. This would allow both northbound lanes on Hamden Drive to turn right and go north onto Coronado to the roundabout concurrently. This is because there would be no northbound traffic at that point south of First Street to conflict with the Hamden movements. All of the connecting side streets would be two way allowing for very good cross connectivity between Coronado and Hamden as well as Gulfview Boulevard.
The Traffic Operations Division is requesting guidance on whether or not to proceed with the one-way pair deployment in the Fall of 2016.
