  • 1. EVALUATION OF EXISTING, FUTURE CONGESTION DEFICIENCIES, AND IMPROVEMENTS
  • 2. Agenda • Existing Conditions • Future Year 2035 Conditions • Downtown Truck Percentages • Loading Zones (Constrained Capacity Locations) • Improvements • Next Steps
  • 3. Existing Conditions • Evaluation of multimodal traffic conditions • Analyzed existing (year 2015) intersection capacity conditions • Analysis included: • Automobile • Truck • Transit • Bicyclists • Pedestrian • Identified constrained capacity locations
  • 4. Existing Conditions: Traffic Data Gathering and Collection • Intersection traffic data gathered from these studies: • City of Miami’s Downtown Miami Transportation Analysis, 2013 • All Aboard Florida – Miami Station, 2014 • Miami Worldcenter, 2014 • Traffic collected at 13 additional intersections • Downtown wide annual growth rate of 1.86% (SERPM 2005 compared to 2035) • Growth rate applied to establish 2015 conditions
  • 5. Year 2015 Intersection Level of Service Figure 1 – Downtown AM Intersection Level of Service
  • 6. Year 2015 Intersection Level of Service Figure 2 – Downtown PM Intersection Level of Service
  • 7. Future 2035 Conditions: Future Traffic Volumes • PortMiami growth/future forecasts for freight and cruise passengers expected to grow significantly by 2035 • Downtown wide annual growth rate of 1.86% applied to 2015 volumes to develop 2035 volumes • Identified committed developments included in analysis: • All Aboard Florida – Miami Station • Miami Worldcenter • 7th Street closure • Miami River Development SAP • I-395 Reconstruction • Children’s Courthouse • Brickell CitiCentre • Miami Science Museum • Element • 1400 Biscayne Boulevard • 1700 Biscayne Boulevard • 888 Biscayne Boulevard • Riverside Tower • The Chelsea

  • 9. Year 2035 Optimized Intersection Level of Service - Signal timing optimization mitigates failure
  • 10. Year 2035 Intersection Level of Service - Intersection fails from 2015 to 2035
  • 11. Year 2035 Optimized Intersection Level of Service - Signal timing optimization mitigates failure
  • 12. Downtown Truck Loading • The PortMiami Tunnel largely successful in alleviating freight and goods movement within Downtown Miami • Right-of-way in Downtown Miami is limited and vacant property is selling at a premium • Transportation improvements must be examined from a multimodal perspective • Optimizing existing transportation network needs to be examined • Existing on-street freight loading activities is a focus. On-street freight loading activities exacerbate congestion in Downtown Miami
  • 13. Downtown Truck Percentages • FDOT study • Examined truck percentages on Port Boulevard east of Biscayne Boulevard before and after PortMiami Tunnel opening • Overall weekly traffic volumes reduced by 35 percent on Port Boulevard • Average weekly truck volume reduced by 77 percent on Port Boulevard
  • 14. Truck Loading/Delivery Observations • Large truck (tractor trailer) loading more significant in A.M. period • Smaller truck (single-unit) loading more significant in P.M. period • Majority of truck loading activity bounded by NE/NW 2nd Street to the north, SE/SW 2nd Street to the south, Biscayne Boulevard to the east, and NW/SW 2nd Avenue to the west • Many trucks utilize designated truck loading zones • Loading zones not always large enough to accommodate trucks • Trucks block sidewalks partially/fully to avoid blocking travel lanes at several locations • Specific locations where truck loading interferes with travel lanes noted in critical multimodal constrained locations
  • 15. Downtown Congestion Improvements • Programmed Improvements: • FDOT I-395 Reconstruction • FDOT Downtown Distributor Improvements • Conceptual Improvements: • City’s improvements on SE 3rd Avenue • Potential Improvements: • I-95 Ramps at NW 8th Street & NW 3rd Court/NW 3rd Avenue • Roadway reconfiguration at SE 1st Street and Biscayne Boulevard to accommodate loading zones • Loading Zone Improvements: • Policy • Physical loading zone improvements • Other Improvement Considerations: • Haz-mat routing accounting for Miami World Center (Existing route information to be provided by FDOT) • Bus-only lanes on select corridors (GPC V-29 Scope of Services)
  • 16. Programmed Improvement • FDOT District 6 I-395 Reconstruction Plans • Improve local access to and from I-395 • North Miami Avenue and SE 2nd Avenue • Reduces weaving along I-395 Mainline for north/south I-95 • Increases capacity to prevent future traffic congestion
  • 17. Programmed Improvement • FDOT District 6 Downtown Distributor Improvements • Additional I-95 on-ramp lane on southbound SE 2nd Avenue
  • 18. Programmed Improvement • FDOT District 6 Downtown Distributor Improvements • Additional I-95 on-ramp lane on southbound SE 2nd Avenue
  • 19. Contemplated Improvement • City of Miami SE 3rd Avenue Contemplated Improvements • Option 1 • One-way SE 3rd Avenue northbound (NB) between SE 2nd Street and Biscayne Boulevard Way • Option 2 • One-way SE 3rd Avenue NB between SE 2nd Street and SE 3rd Street • Signalizes intersection of SE 3rd Street and Biscayne Boulevard • Fully signalizes SE 2nd Street and SE 2nd Avenue • Option 3 • One-way SE 3rd Avenue NB north of SE 2nd Street and one-way SE 3rd Avenue SB between SE 2nd Street and Biscayne Boulevard Way • Removes lane between SE 2nd Street and Biscayne Boulevard Way for on- street parking • Provides third lane from NB Biscayne Boulevard to WB SE 2nd Street • All options provide additional lane to I-95 on-ramp

  • 21. Conceptual Improvements • City of Miami Potential Improvement Plans (Alternative 2)
  • 22. Conceptual Improvements • City of Miami Potential Improvement Plans (Alternative 3)
  • 23. Potential Improvement • I-95 on/off ramps/NW 3rd Avenue/NW 3rd Court at NW 8th Street • Re-designate southbound shared left-turn/through lane as left-turn lane • Extend southbound left-turn lane • Add a second lane to I-95 on-ramp and re-designate the outer through lane at the northbound approach of NW 8th Street as a “choice” lane for I-95 on-ramp or NW 3rd Avenue
  • 24. Ramp Only Choice Lane Exclusive Left-turn Lane Exclusive Left-turn Lane Ramp Only Choice Lane Extend Left-turn Lane Additional I-95 On-Ramp Potential Improvement
  • 25. Loading Zone Improvements • Loading Zone Policy • Policies for truck loading/delivery capacity and livability improvements will be developed • Many metropolitan areas nationwide have implemented ordinances for loading restriction policies Nationwide City Loading Zone Regulations City Loading Zone Regulation Loading Zone Operational Hours Miami Beach Permit Required 30 and 60 minute maximum Chicago Permit Required 30 minute maximum Houston Permit Required 30 minute to 2 hour maximum New York Posted Sign 3 hour maximum Orlando Permit Required 30 minute maximum Pensacola Commercial Loading Zone/General Loading Zone Commercial Loading Zone no time limit General Loading Zone 15 minute maximum Portland Permit Required 30 minute maximum Salt Lake City Permit Required 30 minute maximum San Jose Permit Required 1 hour maximum Seattle Permit Required 30 minute maximum
  • 26. Loading Zone Improvements • Loading Zone Policy: • Proposed freight loading zone regulations/program • Permit Program • Clearly define loading areas • High-emphasis loading zones • Larger loading bays • Define loading hours and maximum loading time periods • Enforcement • City of Miami Police Department • City of Miami Code Compliance Department • Miami Parking Authority • Enforcement Fine Schedule • Public Awareness Program • Delivery purveyors • Businesses • Agency coordination • Residents
  • 27. Loading Zone Physical Improvements • Define required length of loading zone • Maneuverability analysis prepared to determine required length of loading zones • High emphasis loading zones proposed • Improvements proposed at multimodal constrained locations
  • 28. Loading Zone Improvements Loading Zone Length for Head-in Truck Maneuver Truck Type Truck Length Approximate Required Loading Zone Length for Head-in with back- in Maneuver Approximate Required Loading Zone Length for Head-in Only Maneuver Scenario 1 Scenario 2 Single-unit truck (SU-30) 30 feet 45 feet 60 feet Single-unit dual-rear axle truck (SU-40) 40 feet 60 feet 72 feet Intermediate semitrailer truck (WB-50) 55 feet 110 feet 108 feet Interstate semitrailer truck (WB-62) 69 feet 180 feet 127 feet
