The average width and length of the corridors is 5 miles and 17 miles respectively and there are an average of 4 screenlines, or cross sections, per corridor. Highway and transit network performance is measured and analyzed at these screenlines as a peak hourly volume to peak hourly capacity ratio. These corridors were developed based on travel desire-lines from the Southeast Regional Planning Model (SERPM) version 6.5 which represent the total number of daily trips between the 37 Miami-Dade Department of Planning and Zoning Districts (i.e. each desire-line represents the daily trips between two districts). These trips were estimated in the Existing- plus-Committed scenario of the SERPM. The 25 desire- lines with the highest number of daily trips were used to define the ten corridors. The screenlines for each corridor were selected based on input from the Long Range Plan Steering Committee, and major roads running perpendicular to the corridor. While the MNAT is useful to determine the appropriate location, magnitude, and quantity of highway and transit improvements to address deficiencies in the system, it is not a comprehensive tool, nor is it intended to provide final results of simulated network scenarios. The SERPM7 is the tool used to simulate the Base Year, Existing- plus-Committed, Needs, and Cost Feasible Plan scenarios and report system level results, including countywide congestion levels, transit ridership, and hours of delay. Figure 3-4 | Planning Screenline Corridor Locations Table 3-5 | Planning Screenline Corridors Projects from the 2035 Long Range Plan, Agency Master Plans, and MPO studies such as the Arterial Grid Analysis Study were added to the MNAT to form a base scenario for the 2040 Needs Plan. By making changes to these base scenario projects and/or adding new projects to both the highway and transit networks, the 2040 Needs Plan was developed.
