10 SECTION D Project Approach and Understanding RFQ # 21-11-01 PROFESSIONAL PLANNING AND ZONING CONSULTING SERVICES, CIVIL AND TRAFFIC ENGIEERING staff to determine the types of traffic study(ies) required for the proposed project, as well as the methodology for each study. The methodology is defined based on the type of land use proposed and the size of the development/ redevelopment. There are standard key elements that are included in a typical traffic study methodology, including the following: TRIP GENERATION - Trip generation calculations for a proposed development are completed using the relevant land use code for the submitted development application per the Institute of Transportation Engineers' (ITE) Trip Generation Manual, 10th Edition. A multimodal (public transit, bicycle, and pedestrian) factor based on US Census Means of Transportation to Work data is reviewed based on the census tracts in the vicinity of the development to decide whether to apply the site-generated trips for the subject redevelopment. STUDY AREA - A detailed list of intersections, including proposed driveway connections and road segments, must be identified by the applicant for inclusion in the study area. DATA COLLECTION - A schedule, including identification of peak hours, is defined for collecting data at the intersections and road segments in the study area. The methodology defines the peak period during which manual turning movement counts will be collected. Traffic should be counted on a normal weekday or weekend day, as applicable. All traffic counts should be adjusted to peak-season conditions using the appropriate Florida Department of Transportation (FDOT) peak-season category factor. Turning movement counts should be collected in 15-minute intervals during the identified peak period. Turning movement counts are to include pedestrians and bicyclists. Signal timing information is obtained from the Miami-Dade County Traffic Engineering Division. During abnormal traffic conditions, historical traffic data should be used in lieu of new traffic counts, if there is a variance in the traffic operations, such as during the current COVID-19 pandemic, or a tropical storm/hurricane. TRIP DISTRIBUTION - Trip distribution should be determined based on the turning movements counts and on an interpolated cardinal trip distribution for the project site's traffic analysis zones (TAZs) obtained from the current Miami-Dade County TPO’s SERPM model. The trip distribution for the anticipated buildout year should be interpolated from 2015 and 2045 data. BACKGROUND GROWTH RATE - A background growth rate should be calculated based on historic growth trends at nearby Florida Department of Transportation (FDOT) traffic count stations. The committed trips from approved but unbuilt development projects should be included in the analysis. The projects that have committed trips would be provided by City staff. CAPACITY ANALYSES - Capacity analyses should be conducted during the identified AM and PM peak hours at the study intersections. Intersection analyses should be performed using Trafficware's Synchro 10.0 traffic engineering analysis software, which applies the Transportation Research Board's (TRB's), Highway Capacity Manual (HCM), 2000, 2010, and 6th Edition methodologies. The capacity analyses should be conducted for the following scenarios: ● Existing Conditions ● Future Conditions without project ● Future Conditions with project TRAFFIC STUDY/TECHNICAL MEMORANDUM - The traffic impact analysis for the project should be summarized in a technical memorandum to describe the study procedure, key assumptions, traffic assignment methods, findings and recommendations. Information should include the intersection level-of-service, delay and 95th percentile vehicle queue stacking, including existing turn-lane storage. The document should include a summary of the existing conditions of each adjacent roadway facility, including the number of lanes, lane widths, presence of bicycle and pedestrian infrastructure, posted speed limit, school zones, etc. The document should include a narrative regarding active transportation and other multimodal options. It should identify if there are bicycle and pedestrian projects
