West Cervantes Traffic Feasibility Study Jill Lavender, Transportation Planner Cory Wilkinson, AICP CEP, Project Manager Mary Morgan, PE, Engineer
Purpose Determine feasibility of reducing number of lanes on West Cervantes from 4 to 2 Lanes between Dominques and A Streets Dec 2016 - Corridor Management Plan Recommendation: Option B (Road Diet) Option B: West Cervantes Street Road Diet – East of Pace Boulevard. Eliminate two travel lanes and add landscaped median and on-street parking
Study Area Project Limits • 2. 25 miles • As defined by December 2016 Corridor Management Plan
What does this study cover? In this Study ü Traffic Analysis & Results Not in this Study Final Recommendation Conceptual Designs Public Involvement Environmental Analysis FDOT Safety Improvements Any recommendation to proceed with lane elimination study is at discretion of FL-AL TPO.

Adjacent Parallel Corridors Capacity West Navy Boulevard / West Garden Street: • East of North Pace Boulevard There is sufficient capacity if traffic is diverted with the lane elimination. • East of North W Street • West of North W Street West Jackson Street: • East of North Pace Boulevard • East of North W Street • West of North W Street 0% 20% 40% AADT 60% LOS D Capacity 80% 100% 120%
Summary • Additional queuing anticipated Build 2045 (2 lanes) • PM conditions worse than AM • Average speed could be as much as 13 mph lower • Travel time could be as much as 5. 6 minutes longer −with diversion to grid network • Improved delay and queuing with diversion to grid: 20% diversion: 10% diversion: 10. 7 minutes 5. 6 minutes 10. 7 minutes 7. 3 minutes • Sufficient capacity on parallel corridors −W. Navy Blvd. / W. Garden St. and W. Jackson St.
