Consideration of those criteria follows: <br />(a) Traffic engineering principals and traffic investigations <br />(1) Traffic engineering principles were considered in the following areas: <br />- Roadway Capacity; <br />- Intersection Capacity; <br />- Safety; <br />- Signs, Signals, Markings; <br />- Intersection Control; <br />- Roadway Lighting; <br />- Access Control; and <br />- Speed Zoning. <br />• Roadway Capacity is generally reduced by converting from one-way to two-way <br />operation, due to the introduction of additional conflicting movements at <br />intersections. However, these particular segments of roadway are somewhat <br />.underutilized with the subject section of Charnelton carrying approximately 3,000 <br />ADT (average daily traffic) and .the two blocks of 10~' carry approximately 2,000 <br />ADT. These volumes are well below the capacity of a two lane street. <br />• Intersection capacity: The re-designation. will have minor effects on the capacity <br />of the intersections of Charnelton and 10~' Avenue and Olive at 10`" Avenue. <br />These intersections are signalized. and during peak periods may not be capable of <br />serving all movements within the 60 second signal cycle that serves the entire <br />downtown area. <br />• Safety: All potential safety impacts, both positive and negative, are minor. <br />There have been no reported crashes at Charnelton and Broadway in the three <br />year period between January 1, 1998 and December 31, 2000, There were 2 <br />reported crashes at Charnelton and 10`'' Avenue and 15 reported crashes at <br />Charnelton and 11 `~ Avenue during the same three year period. There were 7 <br />crashes at 10~' and Lincoln and 9 crashes at 10`'' and Olive during the same.. period. <br />None of these sites reached a crash rate in excess of 1.00 which is the typical.. <br />threshold considered to indicate a safety concern (11"' and Charnelton is 0.81). <br />Converting a street from one-way to two-way operation can have negative safety <br />impacts since it increases the number of conflict points by introducing additional <br />movements. However, reducing the need for motorists to circle around one or <br />.more blocks to reach a destination can partially mitigate these impacts. <br />• Signs, Signals, Markings: This action will be removing, replacing or altering <br />several signs including the removal of one-way signs, removal and installation of <br />differing regulatory controls and warnings including lane use signs, left turn yield <br />to oncoming traffic signs, and Speed 20 signs. Signals will be altered to add the <br />new signal heads for the added traffic flow direction. Markings will be changed <br />from white one-way denotations to yellow two-way striping and parking Gees, <br />meters and signs will be reoriented to align with the two-way configuration. <br />
