4. Analyses <br />a. Corridor Vehicular Analysis <br />While many factors contribute to a road feeling congested, the two biggest factors <br />are volume, how many vehicles are using the road, and capacity, how many vehicles <br />the 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 <br />volume to capacity ratio of 1.0, where the traffic demand is nearly equal to the traffic <br />supply, 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 The City of Ramsey's Comprehensive Plan. If the Average <br />Daily Traffic (ADT) volume on a roadway is below the threshold, then it is considered <br />un-congested. If the daily volume falls inside the range, the road is almost <br />congested, and if the daily volume is over the threshold the road is congested. <br />• 2-Lane undivided streets are considered congested with a volume between <br />10,000 to 12,000 vehicles per day. <br />• 2-Lane divided streets are considered congested with a volume between <br />15,000 to 17,000 vehicles per day. <br />• 4-Lane divided streets - 28,000 to 32,000 vehicles per day. <br />• 6-Lane divided freeway — 90,000 to 120,000 vehicles per day. <br />To provide an initial planning level screening, Chart 1 provides volume to capacity <br />ratios of the study corridors during each of the study years to determine if any of the <br />roadway corridors are candidates for additional through lanes. <br />Traffic Impact Study 8 <br />Riverstone South Development <br />'#= Spak <br />
