This scope of study is for Phase 1 only. Phase I1 of the study will be undertaken once the required improvements are determined and approved as results of Phase 1. Phase Il will include the 30% design of roadway documents including drainage and landscaping. This Phase I study will analyze the impacts of the developments at both macro and micro levels. An iterative process of analysis will be followed for the final recommendations where the proposed mitigations will be tested and evaluated using micro simulation. The preferred alternatives will be further investigated at a conceptual level. Since the future of Miami downtown is geared more towards multimodal systems of transportation, transit will be an integral part of the analyses. One of the major generators in the area of study is the Port of Miami and a Tunnel to provide relief to the Port traffic has been in the planning stages for a while, however currently the probability of this tunnel becoming a reality is in question. If this tunnel is to be built then it would help significantly alleviate congestion in the downtown area. Our traffic impact study will therefore consider two different scenarios — one with the Port Tunnel and one without it. PBS&J will sub -consult Kimley Horn and Associates (KHA) for the services listed below. The work effort is broken down into following tasks: Tasks for PBS&J Team Task 1: Data Collection and Field Observation Task 2: Update and Run CUBE Voyager Traffic Forecasting Model Task 3: Determination ofAADT, Multi Modal Split & Design Hour Volumes Task 4: Microsimulation Analysis of Existing Conditions Task 5: Microsimulation Analysis of Future Conditions Task 6: Generate/Evaluate Improvement Alternatives Task 7: Conceptual Roadway Configurations for Preferred Alternative Task 8: Recommendations, Presentations and Documentation Task 9: Meetings and Coordination with City and Developer Task 10: Coordination with DRI, SEOPW and KHA • • • Tasks for Sub Consultant (KHA)Team Task 11: Transportation Meetings and Coordination Task 12: Parking Inventory and Evaluation Task 13: Roundabout Analysis The tasks are described as follows: PBS&J Scope Task 1: Data Collection and Field Observation This task includes collecting traffic counts within the area of impact of the Miami World Center. This effort will include additional Turning Movement Counts (TMC's) for two (2) special events. It is assumed that up to five (5) signalized intersections will be counted for a period of four (4) hours during the special events. Additionally the data collection will also include up to seven (7) 7-day bi-directional automatic machine counts on selected roadway segments. All other counts will be obtained from the turning movement counts being performed for the SEOPW DRI. Any available State/County counts relevant for the study will also be obtained and used. All counts will be factored using the Florida Department of Transportation's (FDOT) seasonal adjustment factors to estimate peak season traffic conditions. The signalized intersection operational timing and signal phasing parameters will be obtained from the Miami Dade County Public Works Department and utilized in the microsimulation analysis of the signal system within the area of impact. Field observation will be conducted within the area of impact to help identify and document existing geometric and operational characteristics that will be used in the construction and calibration of the microsimulation model. All other information for the study area like future land use within the area of influence, other committed developments in the area, alignments of planned future transit systems, etc. will be obtained from the City. This will include other relevant input from the City staff, and will be made part of the analysis. Traffic projections for the Port of Miami tunnel will be obtained from Miami -Dade County/Port of Miami. Task 2: Update and Run CUBE Voyager Traffic Forecasting Model PBS&J will develop a model to be used to produce traffic volumes for the build out analysis of the proposed Miami World Center development and the vicinity. The adopted Miami/Dade County Metropolitan Planning Organization's (MPO) travel demand model will be used. The Southeast Regional Planning Model is not being considered for use in this project because its' primary purpose is for the evaluation of regional transportation projects. This project requires a local level of analysis and as such is more suited to the • • • use of the MPO model. It is assumed that the new CUBE Voyager model will be used. The analysis year is assumed to be the year 2030. A review of the model shall be performed to ensure that the model performs adequately in the study area. This will include a review of the base year and the horizon year models. If the model is found to not perform well in any part of the study area, the consultant will make recommendations for changes and submit those recommendations to the City for approval. It is assumed that the year 2030 will be the only year analyzed for this project. The socioeconomic data associated with the Miami World Center project will be entered into the model's year 2030 "ZDATA" file. The procedure for arriving at the number of trips by land use category will be discussed with the City and documented in a tech memo that will need to be signed off on by City prior to the start of the coding of the SE data into the model. This effort will be for a single iteration of land uses only. Additional scenarios will require a supplemental agreement. The model's 2030 highway and transit networks will be evaluated and updated as necessary inside the study area. We already are aware that the City is looking at the Miami Street Car and Bay Link projects. Also, Metro Rail and the Metro mover should see increases in ridership based on more interconnectivity in the area. Once the SE data has been updated, the 2030 model will be run for two base line multimodal scenarios. One of the scenarios will include the Miami Streetcar project and the Port Tunnel project while the second scenario will include the same transit conditions but without the Port of Miami Tunnel. Modifications to the highway network based on the needs identified by the inclusion of the Miami World Center project in each of the two base scenarios will then be coded into the model and run. No more than 2 total multimodal scenarios will be run for testing of the needs. Additional scenarios will require a supplemental agreement. Task 3: Determination of AADT, Multi Modal Split & Design Hour Volumes Once the models have been run and reviewed, the output Peak Season Weekday Average Annual Traffic (PSWADT) volumes will be converted to AADT. This is required for the development of Design Traffic for use in the traffic operations analysis. FDOT produces annually a report by facility type listing Model Output Conversion Factors (MOCF) that allow for the factoring of PSWADT to AADT. This is done by facility type and requires smoothing in order to maintain balanced volumes across facilities. This process will be carried out for each model run. Transit ridership will also be produced by line and mode for the Peak and Off-peak periods. Using the AADTs, the Directional Design Hour Volume (DDHV) will be calculated using procedures from the FDOT Project Traffic Forecasting Handbook (FDOT — 2002). The DDHV will be then be taken and used to estimate future year intersection turning • • movements with the use of the FDOT's TURNS5 program. The TURNS5 output will be the basis of the traffic operations analysis for the future year. Task 4: Microsimulation Analysis of Existing Conditions The collected data in Task I and those provided from other studies like DRI, FDOT, County, etc. will be used to perform traffic operational analyses for the existing conditions. The analyses will be performed in the area of influence at a micro Ievel utilizing a powerful modeling tool; the VISSIM model. VISSIM is the state-of-the-art micro -simulation model with powerful analytical modeling capabilities and robust graphic animation. The existing conditions analysis will generate an estimate of existing roadway capacity excesses and deficiencies and will be used as a base line for the analyses of future conditions which will be conducted at a later task with and without the proposed development. The analysis will be performed for typical weekday AM and PM peak periods and up to two (2) additional special time periods. The additional time periods for example could be during special events at the American Airlines or significantly increased activity in Port of Miami, the exact periods will be decided based on discussions with the City of Miami and the historic trend of seven day counts in the area. Task 5: Microsimulation Analysis of Future Conditions The operational conditions during the typical weekday peak hours and any other additional periods will be modeled for conditions in the year 2030 using the baseline model developed in Task 4. This will include the impacts of the Miami World Center and the year 2030 land use in the area. Two sets of conditions will be evaluated for all the hours of analyses: one with the Port of Miami Tunnel operational, and one without the Port of Miami tunnel. Therefore there will be two models for AM peak and two models for PM peak period with up to two additional sets for the special time periods analyzed in Task 4. The traffic volumes to be used in the peak period models will be obtained from the output of the planning model developed in the tasks above. This task will include analyzing the potential traffic impacts by determining the Measure of Effectiveness (MOE), which will include Level of Service (LOS) and the overall delay and congestion at the critical links and key intersections in the area for all the future time frames analyzed. This also includes qualitative analysis of the impacts (if any) of other modes of travel including buses. The results of these analyses will be interpreted to provide guidance on approaches to formulating a broad set of possible access improvement alternatives. Task 6: Generate/Evaluate Improvement Alternatives The results of the analysis and modeling operational conditions during the various periods conducted in Task 5 above will form the basis for generating improvement alternatives for operational conditions and improving the levels of service of intersections to acceptable levels. • • • PBS&J and the team will identify a wide range of alternatives to include new and "out - of -the -box" ideas. All ideas and options will be included for further screening and evaluation. The screening of the alternatives will be sensitive to cost, funding sources and will be sensitive to the downtown urban environment and aesthetics. The realities of today and the needs of the future for the Miami World Center and other stakeholders within the area of study will be factored in and included. The perceptions and viewpoints of other stakeholders and agencies within the area will be anticipated. Therefore, the screening of options will focus on a "win -win" approach while "Making the Case" for considering the Developer's basic access needs. Once the alternatives are screened and a shortlist of up to three (3) alternatives is developed, they will be examined. Each of the alternatives will be added to the MPO planning model and the traffic volumes will be developed using the tasks detailed above, each alternative will have a set of traffic volumes for the peak periods and scenarios micro analyzed. Each alternative will be modeled and micro analyzed using the models developed in Task 5 and the traffic volumes generated from the planning model. The resultant MOEs from the models will be compared with unmitigated conditions to quantify the traffic operational improvement. Task 7: Conceptual Roadway Configurations for Preferred Alternative In this task conceptual roadway configurations of the preferred alternative from Task 6 will be developed. The alternative will be laid out on the existing roadway system and will help summarize further actions that will be required by the City. This will be including but not limited to sidewalk improvement or elimination, possible lane widening or additional lanes, effects on multimodal system, effects on parking, etc. Conceptual cross-sections/layouts for improved roadway segments will be produced and included in the final report. Task 8: Recommendations, Presentations and Documentation This task includes making the recommendations for all efforts involved on the Miami World Center project including those related to the DRI conducted by others, efforts conducted by KHA and all other efforts within the area of study that have impacts on this study and representing the best interest of the City of Miami. This also includes generating on -going recommendations affecting the study based on the long range modeling effort and the microsimulation modeling effort as stated above. All presentations to the City, County, FDOT and other team members are also included in this effort. The work effort including data collection. assumptions made, analyses conducted, and alternatives generated and analyzed, results and recommendations made will all be summarized and documented in a draft report. This draft report will be finalized upon receiving and incorporating comments from all concerned. • • Task 9: Meetings and Coordination with City and Developer This task will include coordination meetings with the City of Miami and the developer of Miami World Center including the developer's representatives and architects will be conducted as requested/authorized by the City of Miami during the commencement of study and the development of alternatives and recommendations. It is anticipated that there will be up to 10 meetings Task 10: Coordination with DRI SEOPW and KHA This task will include all the coordination between Curtis Group, KHA as well as other parties as requested/authorized by the City of Miami. it is anticipated that there will be up to 10 meetings with the DRI team and up to 10 meetings with KHA. Sub Consultant (KHA) Scope Task 11: Transportation Meetings and Coordination It is anticipated that during the course of the transportation analysis meetings and coordination may be required with the Client (City of Miami/SEOPW CRA), PBS&J, agencies including Miami -Dade County Public Works (MDPW), City of Miami, and Florida Department of Transportation (FDOT). The purpose of these meetings will be to obtain data and information, discuss the appropriate methodology for analyses, and present study results, findings, and recommendations. Task 12: Parking Inventory and Evaluation The first step in preparing the evaluation of parking needs within the study area is quantifying the existing parking conditions. Existing public on -street and off-street parking inventory information will be provided by the City of Miami Parking Authority. This information will be verified in a field review. A parking inventory will be conducted to identify the location and quantity of existing parking for private off-street facilities within the study area. Particular attention will be directed to the use of space underneath existing expressways (1-95 and 1-395). A base map will be prepared showing the location and number of existing parking spaces within the study area. A field review of existing parking usage within the parking study area will be performed to quantify existing parking usage patterns. A parking usage survey will be conducted including public on -street and off-street facilities and private off-street facilities. Based on our understanding of the existing activity in the study area, the parking survey will be conducted during the mid -morning period. Based on the existing parking usage observations, key parking patterns will be identified including specific areas with parking demand surpluses and/or parking demand deficits, and strategies will be developed to address future parking needs. Findings and recommendations will be documented in a parking report. A draft report will be circulated for comments and input. A final report will subsequently be prepared • • • which addresses comments received. Up to 15 copies of the final report will be provided along with a CD containing the report in electronic (PDF) format. KHA will coordinate and attend up to three (3) coordination meetings with the Florida Department of Transportation (FDOT) staff to discuss the potential for using the space under the underpasses for CRA parking. Task 13: Roundabout Analysis A traffic analysis will be prepared for a roundabout alternative at the intersection of NE 15[ Avenue at NE 10`h Street. This analysis will assess the appropriateness of a roundabout at this location. A conceptual layout plan will be prepared of the proposed roundabout. The purpose of the plan will be to provide visional representation of the basic roundabout geometries such as the roundabout footprint (inscribed diameter), entry/exit approaches, and central island. Findings and recommendations will be documented in a report. A draft report will be circulated for comments and input. A final report will subsequently be prepared which addresses comments received. Up to 15 copies of the final report will be provided along with a CD containing the report in electronic (PDF) format.
