9. Year 2035 Optimized Intersection Level
of Service
- Signal timing optimization mitigates failure

10. Year 2035 Intersection Level of Service

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

15. 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

19. 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)

20. 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

21. Programmed Improvement
• FDOT District 6 Downtown Distributor Improvements
• Additional I-95 on-ramp lane on southbound SE 2nd Avenue

22. Programmed Improvement
• FDOT District 6 Downtown Distributor Improvements
• Additional I-95 on-ramp lane on southbound SE 2nd Avenue

23. 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

24. Conceptual Improvements
• City of Miami Potential Improvement Plans (Alternative 1)

25. Conceptual Improvements
• City of Miami Potential Improvement Plans (Alternative 2)

26. Conceptual Improvements
• City of Miami Potential Improvement Plans (Alternative 3)

27. 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

28. Ramp Only Choice Lane

29. 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

30. 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

31. Loading Zone Physical Improvements

required length of loading zones
• High emphasis loading zones proposed
• Improvements proposed at multimodal
constrained locations
