Transcription

1 SCOPE OF SERVICES INTERSTATE 195 CORRIDOR PLANNING STUDY FROM INTERSTATE 95/NW 12 TH AVENUE TO ALTON ROAD (ROADWAY ID MP TO MP 4.910) (ROADWAY ID MP TO MP 4.132) BACKGROUND Interstate 195 is an important limited access facility in Miami-Dade County providing a direct connection between Miami International Airport (via State Road 112), Interstate 95, and the densely populated areas of Miami Beach. The corridor is the one of two (2) limited access facilities in Miami-Dade County connecting the mainland to the barrier island carrying approximately 130,000 vehicles daily. In the City Miami, the corridor provides interchange access to several neighborhoods recently experiencing significant growth: the Design District, Midtown, and Wynwood. With the expected continued growth within both the City of Miami and the City of Miami Beach, travel demand in this corridor is expected to continue to increase over the next 30 years. Geometric expansion opportunities along the corridor are limited within the existing rightof-way. The following interchanges exist within the study limits: NW 12 th Avenue (partial), Interstate 95 (system-to-system), North Miami Avenue (partial), Biscayne Boulevard (full), and SR 907/Alton Road (full). It should be noted that an ongoing corridor planning study is underway for Interstate 95 within Miami-Dade County that is examining the Interstate 195/State Road 112 interchange. BACKGROUND The purpose of this scope of services is to evaluate existing conditions and deficiencies, identify needs, and develop and evaluate improvement concepts. The study incudes the evaluation of study interchanges, interchange influence areas, and ramp junctions to identify deficiencies focusing on reoccurring bottlenecks and development of a series of proposed improvements to address existing and future (short-term and long-term) demands of the corridor. If necessary, multiple improvement alternatives will be developed for the mainline and system-to-system connections. The study will also evaluate the feasibility of providing bicycle/pedestrian facilities for providing a connection from City of Miami Beach to the City of Miami. Page 1 of 17

4 Alternatives Development Task 4 Performance Measures Performance measures and targets will be developed specifically for the project. These performance measures are intended to assist in the evaluation of alternatives and to provide a basis for evaluating improvements on subsequent studies. With current Fixing America s Surface Transportation (FAST) Act and Moving Ahead for Progress in the 21st Century Act (MAP-21) requirements, FDOT Central office has been developing performance measurements and targets, system wide and corridor wide. It is the desire of this project to further develop performance measurements that are consistent with community goals and objectives and that address technical concerns that are identified in FAST Act MAP-21. Performance measures will be developed for the following areas: mobility, quality of travel, safety, energy and environmental impacts, and freight movement. The FAST Act and FHWA have adopted regional models of cooperation as an emphasis area, with performance measures for regional collaboration in areas such as technology and tools, institutional arrangements and governance, and performance management processes. These measures will be incorporated into the I-195 Corridor Study through the Public Information and Intergovernmental Coordination, including coordination and collaboration with partners throughout the development of the study, and sharing of data and information. The approach for developing performance measurements for this study will be to assemble a draft set of performance measures and targets building upon the efforts of FDOT Central Office and District Six and taking into consideration the information available from existing data sources. The draft performance measures will be presented in a draft technical memorandum. After the review period, refinements will be implemented and a final document will be created and used as a guiding document throughout the course of the study. The results of this task will be summarized in a final memorandum. Task 5 Data Collection This task consists of assembling the transportation planning, social, economic, and environmental data and information within the corridor and the area influenced by the corridor. These activities should draw upon the latest existing data, as feasible and appropriate, including recent studies for both the Interstate 195 and Interstate 95 corridors. The amount of new traffic data collected should be sufficient to develop conceptual improvements. Pertinent data will be collected for the entire corridor including previously completed studies and new traffic data along the corridor. Data collection will consist of the following: a.

Travel Time Data A six (6) hour travel time and delay study will be conducted in both directions along the mainline of the corridor during a typical weekday. The study will be conducted consistent with the most recent version of the FDOT Manual on Uniform Traffic Studies (MUTS) Manual. A minimum of ten (10) travel time runs in direction should be performed as part of this task. 13. Supplemental Traffic Data Additional traffic data will be collected as required for modeling/operational analysis purposes. This will include additional speed, lane utilization, vehicle classification, travel time, weaving, queuing, delay, and origindestination, as necessary. A maximum budget will be established as part of this scope of services for these types of additional data collection, and the specific types and locations will be determined during the initial phases of this project. 14. Crash data The most recent available crash data (5-years) will be obtained from FDOT s crash database (on-system) along the corridor and within interchanges/interchange influence areas, as needed. No off-system crash data will be collected/compiled as part of this task. Summary reports shall be prepared to identify crash frequencies along the I-195 mainline and along ramps, predominant crash patterns, high crash locations, severity of crashes and other pertinent crash statistics. 15. Operational Field R eviews Initial field reviews will be conducted to identify preliminary operational deficiencies on the corridor's mainline, interchanges, and interchange influence areas during the two (2) weekday peak periods of two (2) hours in duration. In addition, the visits will determine/verify signal phasing information, such as protected/permitted left-turn operation, right-turn-on-red restrictions, and phase overlaps. These field reviews will be conducted via passenger car and or/sun Page 7 of 17

8 Guide Center observations for the corridor mainline. Individual site visit field reviews will include interchanges/interchange influence areas. Two (2) staff members will perform these field reviews. Task 6 Existing Conditions Data Analysis An existing conditions data analysis will be performed for the data collected as part of Task 5: Aerial photography, current transportation plans, typical cross sections, right-of-way, ITS equipment, utility infrastructure, drainage system, and public transportation data. The geometric (horizontal and vertical) analysis will be conducted at a level of detail consistent with the data provided by FDOT. The analysis will be summarized in a report with exhibits. Traffic and crash data analysis will be performed as part of other tasks in this scope of services. Task 7 Future Traffic Volume Forecasting Future year forecasts will utilize the Southeast Florida Regional Planning Model (SERPM). The most recent version of the SERPM model at the time of contract notice to proceed will be utilized. Future traffic projections will be developed for future no-build and future build conditions and will be used to prepare improvement concepts for roadway typical sections, interchange, and intersection designs. A traffic volume forecasting methodology memorandum will be developed, reviewed, and approved by FDOT prior to the development of future traffic forecasts. Average daily traffic, design hour volumes, and AM and PM peak hour turning movement volumes will be developed for the present year and two (2) future year horizons: short-term (year 2025) and long-term (year 2045). The development of future traffic volumes will be consistent with the policies and procedures outlined in FDOT s Project Traffic Forecasting Handbook and Project Traffic Forecasting Procedure (# ). Future AM and PM peak hour traffic forecasts for intersections will be developed using the FDOT's TMTool or a similar analysis tool. SERPM will be utilized to produce forecasts for the two horizon years to test various infrastructure improvement and operational strategies in the I-195 study. Future year AM and PM turning movement volumes will be developed for the 27+/- intersections within the study corridor based on differences between model estimates and observed data using the FDOT's TMTool or a similar analysis tool. The results of this task will be summarized in Design Traffic Technical Memorandum. Task 8 Operations Model Development A VISSIM micro-simulation model will be developed for I-195 from east of Alton Road (E) to west of the I-95 interchange area/nw 12h Avenue including all crossing interchanges and adjacent intersections that have influence on operations for both the AM and PM peak periods. These simulation models will assist in analyzing the operational performance for the corridor. Another objective is to develop a micro-simulation model that can be used for analyzing operations on subsequent studies after this study is completed (e.g., future PD&E studies). The VISSIM model will be calibrated to existing conditions based on FDOT/FHWA guidelines and criteria. The calibrated VISSIM model will be used to develop models of future long-term no-build (future traffic Page 8 of 17

9 without improvements) and build alternatives (future traffic with improvements). Simulation analyses will be performed to assess operating conditions for the network within the I- 195 area of influence. VISSIM traffic simulation models will be used for evaluating traffic operations for the no-build alternative and the build alternatives. The following scenarios will be analyzed: 2017 Existing Conditions (model calibration) 2030 No-Build and Build Alternatives (short-term) 2045 No-Build and Build Alternatives (long-term) Due to the complexity of the study area, the likelihood that there could be several alternatives for each interchange location and several typical section alternatives for the I-195 mainline creates the possibility of multiple full corridor build alternatives; therefore, it will be necessary to employ a modeling strategy that capitalizes on the analysis tool and minimizes resources. The number of build alternatives modeled in the full VISSIM model that is documented in the final reports will be limited one (1) build alternative for short-term conditions and three (3) build alternatives for the long-term conditions. The short-term build alternative run will examine the short-term improvements identified through the study area as a basis of comparison to the shortterm no-build alternative. The long-term model runs will be managed such that the final model alternative for the long-term design year will be represent the recommended long-term alternative. The two (2) initial alternative runs for the long-term conditions will be used to test a range of concepts that can be used to learn about the best features that should be part of the recommended third long-term alternative. The following subtasks describe in detail the VISSIM Simulation work to be performed: a. Prepare Existing Conditions Model An existing conditions model will be prepared for both AM and PM peak periods. These models will be constructed based on the following items, which will confirm that the calibration process is performed properly: Finalize model limits Code geometry Code signals/traffic control Code traffics volumes/routing Enter AM and PM traffic data Error checking Prepare output processing The model limits extend approximately 5 miles along I-195 from west of I-95 to Alton Road (E). All study interchanges (NW 12 th Avenue, I-95, North Miami Avenue, Biscayne Page 9 of 17

10 Boulevard, and Alton Road) and mainline portions will be included. The interchange areas of influence will consist of the intersections outlined in Task 5.c.13.b and all connecting/adjoining roadway segments. Since the alternatives will include potential connections to the 95 Express lane system, the model will include the sufficient coverage of the 95 Express lane system to adequately evaluate the impacts of new connections. Data used in the development of the simulation models may be grouped by network geometry, traffic control devices, and traffic volume information. Simulation development will be in accordance with the FDOT s Protocol for VISSIM Simulation. The overall deliverable for this subtask is the AM and PM peak period VISSIM, un-calibrated existing conditions models. b. Existing Model Calibration Once the existing conditions VISSIM model is constructed and error-checked, the simulation model will be calibrated to replicate the traffic performance of the existing conditions (2017). The calibration of the existing AM and PM peak period models will adhere to the criteria and measures specified in the FHWA Traffic Analysis Toolbox Volume III. The VISSIM simulation development and calibration procedures/parameters will be documented as part of the Existing Conditions efforts including the following: Establish Statistics and Criteria Calibrate AM peak model Calibrate PM peak model Prepare calibration summary tables and figures c. Future No Build Models/Analyses No-build traffic analysis will be prepared for both the short-term and the long-term horizon year. These models will consist of existing conditions with future traffic demands applied. The model will include both AM and PM peak periods. The overall deliverable for this subtask is the AM and PM peak period shortterm and long-term no-build models (4 models total) and summary tables of MOEs. d. Short-Term Build Model/Analysis - One (1) short-term (2030) built alternative model for both the AM and PM peak periods will be prepared based on the concept design work prepared in other tasks. The improvements are anticipated to reflect improvements that will improve operations but require minimal/moderate modifications to the corridor within the existing right-of-way. The deliverables for this subtask will be AM and PM peak period short-term build models (2 models total) and summary tables of MOEs. e. Long-Term Build Models/Analyses Three (3) long-term year models will be prepared based on the concept design work prepared in other tasks. The first two (2) complete system alternatives will test a range of design potential improvements. The results of these two (2) models will be used to help create a third and final alternative. The longterm alternatives are anticipated to reflect more robust construction, including mainline/ Page 10 of 17

11 express lane and system-to-system improvements. The deliverables for this subtask will be AM and PM peak period long term build models (6 models total) and summary tables of MOEs. f. Model Documentation A summary report of the modeling work will be prepared. The document will focus on providing sufficient documentation so that future projects that will need to reanalyze alternatives in the corridor may re-use the same VISSIM models. The summary report will include output used for the assessment of various MOEs consisting of the following: Corridors/Routes - vehicle trips, travel time, and speed Interchange Ramps/Intersections - turning movement volumes, delay times, and queue lengths Overall Network - vehicle trips, travel time, and delay time The simulation outputs will be used for comparing build and no-build alternatives. MOEs that will be assessed from the VISSIM models include travel time sections, node evaluations, link evaluation segments, and network-wide output. Task 9 Operational Analysis Intersection, corridor, and interchange influence area capacity analyses will be performed based upon software based on the Highway Capacity Manual (HCM) 2000 and 2010 Editions, as applicable, and VISSIM software. The analyses will be consistent with the guidelines outlined in FHWA s Traffic Analysis Toolbox technical documents and will evaluate the corridor's operations based upon the appropriate MOEs including, but not limited to, density, level of service, delay, volume-to-capacity ratio, queue length, travel time, throughput, and speed. Queue spillbacks from exit ramps onto I-195 shall be documented, and the conceptual design alternatives shall address existing and future spillback onto I-195. The analysis will include existing conditions, future short-term and long-term without improvements (No Build Alternatives), and future short-term and long-term with improvements scenarios (build alternatives) during applicable two (2) peak periods (AM and PM). The shortterm analysis will examine one (1) geometric scenario (build alternative) for the short-term horizon. The long-term analysis will examine two (2) geometric scenarios (build alternatives) for the long-term horizon along with one (1) final analysis for the long-term recommended build Alternative. The operational analysis will be the basis for the development of short-term and long-term conceptual improvements. Software analysis tools that may be used for the traffic operational analysis include the most recent version of the Highway Capacity Software (HCS) for ramps/weaving analyses and Synchro/Simtraffic for intersection analyses. Existing condition Synchro analyses will be calibrated from the collected traffic data and peak period field reviews (queue lengths, lane utilization, etc.) HCS will be utilized to examine ramp areas and merge/diverge areas. The results of the analysis will be summarized in an operational analysis report. Page 11 of 17

12 Task 10 Safety Analysis A corridor wide safety analysis will be conducted as part of this study using the latest five (5) years of crash data compiled and obtained as part of Task 4. The analysis will consist of GISbased crash clustering to identify concentrations of crashes along the mainline and ramps by frequency, crash type, direction, etc. Collision diagrams are not included in the scope of services. Field reviews will be conducted to identify improvements based upon the prevalent crash patterns to identify potential causes and countermeasures. The safety analysis will identify improvements to specifically address crash patterns along the corridor, ramps, ramp terminals, and interchanges. This analysis will assist in determining locations with high crash rates and trends that would indicate the need for a conceptual design improvement. Where possible, the analysis should identify general countermeasures to address multi-modal crash patterns. The analysis will be conducted using the Highway Safety Manual s Predictive Method where applicable. The results of the analysis will be summarized in a safety analysis report. Task 11 Conceptual Improvement Development A series of conceptual improvements will be developed in response to the deficiencies identified in the operational analysis for the short-term and long-term horizon. The improvements will be developed using the latest editions of the FDOT Design Standards, FDOT Plans Preparation Manual, and A Policy on Geometric Design of Highways and Streets, 6 th Edition (AASHTO Green Book). The improvements will be developed at a conceptual level utilizing aerial photography and available as-built plans. The purpose of the development of the conceptual improvements is to determine the general feasibility, identify right-of-way impacts, determine critical design issues, and develop order of magnitude construction costs. Horizontal and vertical alignments, estimated acreage of right-of-way, utilities, extent of locations for retention basins, lighting and sign structures, and other design features that may be pertinent to the analysis of the alternatives will be considered. Field reviews will be conducted to verify the vertical and horizontal geometry and to confirm feasibility of the potential improvements. The conceptual improvement plan will include the evaluation of potential bicycle and pedestrian facilities along the corridor from SR 907/Alton Road to SR 5/US 1/Biscayne Boulevard, specifically addressing the existing share-use path on the eastern section of the corridor. Concept design plans for short-term and long-term horizon years will be prepared for final recommended alternatives on aerial base plans sheets at a scale of 1 = 100. Key features will be labeled. Typical sections for final recommended alternatives will also be prepared. These typical sections will be prepared for each where the existing or proposed typical section differs significantly. a. Short-Term Conceptual Improvements Short-term improvements will be developed for the corridor and interchanges based upon the deficiencies identified in the existing conditions analysis and operational analysis performed for the short-term (2030) no-build alternative. Short-term improvements may include but not be limited to, intersection Page 12 of 17

13 operational improvement within influence areas, auxiliary ramp lanes, and new/reconfigured interchange ramps. Improvements may include alternative corridor enhancements including corridor/incident management, active traffic management, and transportation systems management and operations (TSM&O) concepts. The majority of the short-term improvements are not expected to require right-of-way acquisition that would reduce the potential for short-term implementation. Concept design plans will be prepared for the recommended short-term alternative on aerial base plans sheets at an acceptable scale. A maximum number of 40 plan sheets will be prepared. The extent of the improvements and drawing scale will determine the number of sheets needed. Key features will be labeled. Typical sections for final recommended short-term alternative will also be prepared. These typical sections will be prepared for each area where the existing or proposed typical section differs significantly. A maximum of fifteen (15) typical sections are anticipated in this scope of services. Construction cost estimates will be developed for the recommended short-term build alternative. The cost estimate will be developed using the Long Range Estimate (LRE) system. The LRE will be updated one (1) time during the course of the study. b. Long-Term Conceptual Improvements Long-term improvements will be developed for the corridor and interchanges based upon the deficiencies identified in the existing conditions analysis and operational analysis performed for the long-term (2045) no-build alternative. Multiple improvements within the recommended alternatives are anticipated to address long-term operational deficiencies ranging from broad corridor wide improvements to location-specific improvements. Improvements may include alternative corridor enhancements including corridor/incident management, active traffic management, and transportation systems management and operations (TSM&O) concepts. The corridor will be divided into three (3) sections for purposes of long-term conceptual improvement development: Western Section West of I-95 interchange to East of SR 5/US 1/Biscayne Boulevard interchange. Central Section East of SR 5/US 1/Biscayne Boulevard interchange to West of SR 907/Alton Road interchange Eastern Section SR 907/Alton Road interchange The task includes the development of two (2) long-term improvement concepts for the 2045 design year. In addition, a preliminary analysis will be performed for two (2) conceptual sketch level set of improvements at each interchange/interchange influence area in the long-term horizon, which will be further analyzed in the operational analysis outlined in Task 8. Conceptual design development refinements will be prepared for the preferred long-term alternative at each location. These long-term concepts will be Page 13 of 17

14 evaluated from the standpoint of constructability considering how the improvement alternatives can be implemented independently. Concept design plans will be prepared for final recommended long-term alternative on aerial base plans sheets at a scale of 1 = 100. A maximum number of 40 plan sheets will be prepared. The extent of the improvements and drawing scale will determine the number of sheets needed. Key features will be labeled. Typical sections for final recommended alternatives will also be prepared. These typical sections will be prepared for each where the existing or proposed typical section differs significantly. A maximum of fifteen (15) typical sections are anticipated in this scope of services. Construction cost estimates will be developed for the recommended long-term Build Alternative only. The cost estimate will be developed using the Long Range Estimate (LRE) system. The LRE will be updated one (1) time during the course of the study. The results of this task will be summarized in a Conceptual Improvements Plan Report. Task 12 Environmental Analysis The purpose of the environmental analysis will be to support future Efficient Transportation Decision Making (ETDM) processes (to be completed by others). A preliminary environmental analysis will be conducted. Tasks will include the following: a. Conduct Desktop Noise Impact Analysis - Identify noise-sensitive sites along the corridor and those within generalized LOS C noise impact contours not already protected by existing noise barriers. Summarize potential noise wall mitigation strategies and planninglevel costs. No field noise measurements will be collected. b. Conduct Preliminary Environmental Evaluation Review available project background information. Coordinate with CEMO/GeoPlan as necessary to enter Area of Interest GIS linework into the (internal/non-public) Environmental Screening Tool (EST) for the 5-mile corridor. Develop preliminary Project Description and Purpose and Need Statement. Review and summarize EST GIS analysis results and compile EST inputs needed to evaluate the mainline. The results of the analysis will be summarized in an environmental analysis memorandum. Task 13 Conceptual Improvement Evaluation/Prioritization A matrix evaluation will be developed comparing each of the long-term improvement alternatives to determine the relative impacts and costs associated with each alternative action. The matrix Page 14 of 17

15 evaluations shall compare each alternative by category and result in a ranking of viable long-term alternatives. The objective of this comparison is to select the most viable alternative. Items to be evaluated include at a minimum: Construction costs Right-of-way acquisition Pre-construction, design and construction engineering inspection (CEI) costs Relocations required Traffic and transit operations, demand/capacity reliability Environmental mitigation impacts The long-term preferred improvements will be evaluated to identify a prioritization matrix to provide guidance on the improvements that are most cost effective and implementable. Detailed evaluation criteria will be developed and submitted to stakeholders for input. Performance measures specific to the corridor will be identified and incorporated in the matrix. The final report will provide recommendations for preferred alternatives based upon this evaluation as well as phasing/prioritization of implementation. Reporting Task 14 Reporting and Documentation The following reports will be prepared as part of this analysis: a. Public Involvement Program b. Agency Coordination Documentation Report c.
