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