CMP Part 4A. Transportation Plan <br /> Roadway Capacity <br /> A roadway's capacity indicates how many vehicles may use a roadway before it experiences <br /> congestion. Capacity is largely dependent upon Table 4A-5 Design CVacity <br /> the number of lanes. The table below Table 4A- `b <br /> 5 lists planning-level thresholds that indicate a Roadway Type Daily Capacity <br /> roadway's capacity. Additional variation (more Planning Level(ADT) <br /> or less capacity) on an individual segment is Two-lane undivided 10,000 <br /> influenced by a number of factors including: urban <br /> amount of access, type of access, peak hour Two-lane undivided 15,000 <br /> percent of traffic,directional split of traffic,truck rural <br /> percent, opportunities to pass, and amount of Three-lane urban 17,000 <br /> turning traffic, the availability of dedicated turn (two-lane divided <br /> lanes, parking availability, intersection spacing, with turn lanes) <br /> signal timing and a variety of other factors. <br /> Roadway Capacity—Traffic Forecasting <br /> The Metropolitan Council uses Transportation Analysis Zones (TAZs) for traffic <br /> forecasting.Each forecast study area, in this case the City of Orono, is divided into a series <br /> of TAZs (see Map T34A-3). The TAZ data for Orono can be found at Appendix A. The <br /> modeling shows the majority to the projected growth in the city within the TAZs that <br /> correspond with City Municipal Utility Service Areas (MUSA) which further corresponds <br /> to the cities areas for higher existing and planned densities. <br /> Current and Future Regional/Hennepin County Capacity <br /> At the planning level, capacity problems are identified by comparing the existing number <br /> of lanes with current traffic volumes. The table below illustrates the existing number of <br /> lanes on state and county arterial roadways within the City. To identify the need for <br /> potential future capacity improvements, Hennepin County compared 2030 forecasts to <br /> planning-level roadway capacities. Nearly all State and County roadways within the City <br /> have adequate capacity to handle forecast 2040 traffic volumes with little to minimal <br /> congestion. (See Map 4A-T-4). Based on traffic counts in 2015 the only Hennepin County <br /> road currently undersized based on capacity is Shoreline Drive(CSAH 15). The 2015 ADT <br /> for CSAH 15 was 17,600. Those roads projected to exceed their design capacity by 2030 <br /> are highlighted red below. <br /> City of Orono Community Management Plan 2020-2040 Part 4A, Page 9 <br />
