<br /> 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 Charneiton 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`h Avenue during the same three year period. There were 7 <br /> crashes at 10`h 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 tees, <br /> meters and signs will be reoriented to align with the two-way configuration. <br /> <br />
