PROJECT FACTS
  • The objective of this effort was to develop feasible improvements from an operational, safety and roadway design perspective in order to make traffic flow smoothly at all the intersections and along the entire roadway network on Old Cutler Road. The recommended Alternative 3 involves replacing only four signalized intersections on Old Cutler Road and constructing two-lane roundabouts at those intersections depending on available right-of-way. The remaining intersections where a two-lane roundabout is not feasible will remain as signalized intersections. The four intersections suitable for two-lane roundabouts are as follows:

» Old Cutler Road at SW 67th Avenue

» Old Cutler Road at SW 136th Street

» Old Cutler Road at SW 152nd Street

» Old Cutler Road at SW 184th Street

LOCATION
  • The following signalized intersections along Old Cutler Road from SW 67th Avenue to SW 184th Street:
  • Old Cutler Road at SW 67th Avenue
  •  Old Cutler Road at SW 136th Street
  •  Old Cutler Road at SW 144th Street
  •  Old Cutler Road at SW 152nd Street
  •  Old Cutler Road at SW 168th Street

PROJECT FACTS
  • The purpose of the effort included highlighting the importance of freight mobility in Miami-Dade County, updating the plan from 2014 to 2018, preparing a standalone application for a Countywide self-designated Freight Logistics Zone (FLZ) and to coordinate with freight stakeholders to prepare a list of freight transportation project needs for the 2045 Long Range Transportation Plan (LRTP). The update was guided through close coordination with a Study Advisory Team (SAT) including CSX Transportation, FDOT District 6, FEC Railroad, Florida’s Turnpike Enterprise (FTE),  Miami-Dade County Aviation Department (MDAD), Miami-Dade County Department of Transportation and Public Works (MDDTPW) and PORTMiami. This project also included outreach to all Miami-Dade County Cities and presentations to, and input from, the TPO Freight Transportation Advisory Committee (FTAC).

PROJECT FACTS
  • The ultimate objective of this project is to update the Pavement Evaluation & Five-Year Maintenance and Rehabilitation Report, March 2017. This will be completed by performing a survey of all City-owned roads, determining roadway conditions using PCI rating, and identifying a future five-year pavement maintenance and rehabilitation (M&R) plan for the City of Doral.

PROJECT FACTS
  • MARLIN Engineering was retained by the City of Hollywood Community Redevelopment Agency (CRA) to perform a traffic operational analysis for a proposed two‐way street conversion of Tyler Street. Tyler Street is currently a short three block segment that has three lanes operating as a one-way roadway in the core of downtown Hollywood. The street has generally low traffic volumes and experiences high speeds relative to the downtown context of the area.
  • MARLIN analyzed the roadway segment of Tyler Street from 21st Avenue to Young Circle to a two‐lane, two‐way traffic pattern while maintaining the on-street parking on both sides of the street. The analysis included a conversion to two-way operations including two alternatives, one with the two way left turn lane in the center and the other with increased sidewalks widths. The results indicated that the roadway would operate at acceptable levels and could be redesigned in context with the area allowing for new landscaping, a better bicycle and pedestrian environment and maintain the existing one street parking redesigned for both directions.

PROJECT FACTS
  • MARLIN provided traffic engineering and transportation planning services for the City of Miami. The traffic engineering services included performing preliminary field visits to evaluate the existing conditions, 24-hour volume and speed studies, data analysis, and crash analysis. Several public meetings were also conducted to identify any public concerns related to traffic mobility along local residential streets. Finalizing the traffic calming plan included creating traffic calming criteria, and developing prioritization and scoring models. Feasible alternatives and appropriate solutions for implementation were recommended for the warranted intersections or roadway segments.

     As part of the Citywide Traffic Calming Master Plan, several traffic calming studies were performed at areas such as the Shenandoah, Silver Bluff, the North Grove, the Roads Neighborhood and the Flagami Area. To reduce adverse traffic impacts such as speeding and excessive volumes within the areas and to improve safety and amenity, several traffic calming measures were recommended. These traffic calming measures included both the Passive Control Measures and the active Physical Control Measures. Some of the traffic calming devices recommended to improve mobility and safety in the City of Miami areas included roundabouts, traffic circles, extended chokers, full chokers, narrowed lanes, and forced turn islands.
