FDOT’S VISION FOR ARTERIAL AND FREEWAY OPERATIONS

• To operate our transportation system at the highest-level of cost-effective performance resulting in – Reduced excess delay on

arterials AND freeways – Real-time management

and traveler information for all modes

– Seamless coordination with ALL operating agencies

• Part of the FDOT’s 5-Year Work Program Plan for FY 2015 – FY 2019

• Part of the FDOT’s TSM&O Strategic Plan

• Collaborative effort between FDOT and MDC

Objectives • Ensure a smooth flow on SW 8 Street by improving system performance for the

through movements

• Improving or maintaining performance for both major and minor movements

• Increase system throughput, where feasible, by better assignment of the green time

• Improve travel time reliability

• Improve safety

• Better accommodation of special users and conditions

• Reduce environmental and energy impacts

• Maintain effective agency operations

Project Limits

SW 8 STREET ASCT PILOT PROJECT

• Major east-west route with interchanges at Turnpike and SR 826 (Palmetto Expressway)

• Highly congested with limited opportunities for adding new lanes

• Signal spacing

• Includes major traffic generator such as FIU

• Includes major cross street intersections

SW 137 Avenue, SW 127 Avenue, SW 107 Avenue, SW 87 Avenue

• There will be two major work zones during the evaluation period (planned construction projects at Turnpike Interchange and SW 107 Avenue)

• Two railroad crossings (CSX and FEC railroad crossings at SW 70 Avenue)

• Varying lane configurations

InSync System Deployments

Nation 2000 intersections 31 states

Florida 270 intersections (deployed) 97 (scheduled)

SW 8 STREET ASCT PILOT PROJECT

• Pinellas County (SR 580) – Reduced travel time (5% to 31%) and stops (22% to 74%) – Cross street delay results were mixed – Overall Benefit Cost ratio 20:1

• Other on-going evaluations (Deland, Bay County and Palm Beach County) – Significant improvements in travel time and delay reductions in

off-peak conditions – Awaiting results during saturated conditions and impacts to side

streets – No customer complaints – Significant improvements in transition after railroad preemption
