The primary function of minor arterials is mobility. "A" minor arterials • <br />are classified by the Met Council as "reliever" routes, which provide <br />direct relief to congested principle arterials. "B" minor arterials provide <br />important connections through the City and region. Collector roadways <br />provide access to adjacent land by connecting the local street network <br />and the arterial roadways. Collectors may need to accommodate higher <br />speeds traffic and also serve direct property access. Local roadways are <br />intended to serve direct property access. Local streets are characterized <br />by short blocks and a grid system. <br />2.1.2 2030 Traffic Forecasts <br />The Metropolitan Council guidance provides two options for developing <br />traffic forecasts. One option is to use the regional model and the second <br />option is a historical trend analysis, which is recommended for <br />developed communities. The City of Falcon Heights is considered a <br />developed community. Redevelopment may occur during the planning <br />time frame, but none that would be expected to result in traffic growth <br />significantly different than the historical growth. <br />Historical traffic volumes have been collected from MnDOT's traffic <br />flow maps for the period between 1980 and 2005. Historical growth <br />rates were projected to 2030 along a linear trendline to determine the <br />2030 traffic volumes. For instances where the trendlines indicated a <br />historical decrease, it was assumed that no growth would occur and the <br />2005 ADT would remain the same through 2030. See Figure 1 for the • <br />existing and 2030 traffic volumes on collector and arterial roadways. <br />Most roadways are expected to experience minimal growth in the City <br />with the exception of Snelling Avenue, which, as a regional facility, is <br />expected to experience the greatest amount of growth. <br />Future roadway capacity deficiencies have been identified based upon <br />the future daily traffic forecast. The existing numbers of through lanes <br />on the collector and arterial roadways are also displayed in Figure 1 as <br />well as the number of through lanes anticipated to serve future demands. <br />The existing roadway network should serve the 2030 traffic volumes <br />with the exception of Snelling Avenue. Options for increasing capacity <br />will need to be evaluated in light of proposed 2030 traffic volumes along <br />Snelling Avenue <br />• <br />TComprehensive Plan UpdateT <br />City of Falcon Heights <br />AFAL000701.00 <br />Page 4 <br />
