5. Operational Analyses <br /> a. Corridor Vehicular Analysis <br /> While many factors contribute to a road feeling congested, the two biggest factors are <br /> volume, how many vehicles are using the road, and capacity, how many vehicles the <br /> road can accommodate a day. Transportation professionals use these pieces of <br /> information to create a ratio of volume to capacity. For example, a road with a volume <br /> to capacity ratio of 1.0, where the traffic demand is nearly equal to the traffic supply, <br /> will feel congested to motorists. <br /> Below is a rough guide of the daily traffic volumes different types of roads can <br /> accommodate based on standards for counties in the area. If the Average Daily Traffic <br /> (ADT)volume on a roadway is below the threshold, then it is considered un-congested. <br /> If the daily volume falls inside the range, the road is almost congested, and if the daily <br /> volume is over the threshold the road is congested. <br /> • 2-lane undivided, urban street (one lane in each direction): 10,000 vehicles per <br /> day. <br /> • 3-lane undivided, urban street (one lane in each direction with center left turn <br /> lanes): 15,000 vehicles per day. <br /> To provide an initial planning level screening, Chart 1 provides volume to capacity ratios <br /> of the study corridors during each of the study years to determine if any of the roadway <br /> corridors are candidates for additional through lanes. This type of planning-level <br /> screening does not account for lane widths. As shown, the existing roadway corridors <br /> provide for acceptable operations with their current geometry. <br /> Chart 1 — Study Corridor Volume to Capacity <br /> Z.z <br /> Cunge�i�:d- vulunit<<apeciiy of i.0 <br /> 1 �.,.� �,R.s...e. �..e.��.�a.e�e��.� so ��a�� � .a �_ .F �,a... s. .. <br /> 0 <br /> � <br /> � <br /> � 0.8 <br /> +� <br /> u <br /> ro <br /> Q <br /> v 0.6 <br /> 0 <br /> � <br /> v <br /> � 0.4 <br /> � <br /> 0 <br /> > <br /> 0.2 <br /> 0 <br /> � �: ��' � �� �� <br /> Patriot Ave- Patriot Ave- Main S-West Main St-East Main St-East Front St- Rasmussen Rd <br /> North of Main South of Main of Patriot Ave of Patrlot Ave of Rasmussen South of -North of <br /> St St Rd Patriot Ave Main St <br /> ■Existing 2024 2039 <br /> Traffic Study 6 �7!L-L�li7CONSULTING <br /> Pequot Lakes ��� <br />
