' 9 Roadway Segments The Jack Tone Road segments within the study area are projected to operate at an year 2020 average daily traffic based LOS "D"or worse conditions with the existing two-lane arterial/ruraI highway cross-section. However, the year 2020 base AM and PM peak hour flow on Jack Tone Road are projected to be just less than 1,350 vehicles,which corresponds to a peak-hour based year 2020 LOS "C" for the Jack Tone Road segment between S.R.8818.R.12 and Brandt Road and LOS "D" for the Jack Tone Road segment between Brandt Road and Kettleman Lane. It is recommended that the currently existing two-lane rural highway segment on Jack Tone Road between Brandt Road and Kettleman Lane be upgraded to a two-lane arterial section(with moderate access control)under year 2020 base conditions. With this improvement,the Jack Tone Road segment between Brandt Road and Kettleman Lane is projected to operate at year 2020 base LOS "C" conditions. For all other roadway segments within the study area, the existing capacities are projected to provide acceptable roadway traffic operations under year 2020 base conditions. No other roadway mitigation measures are recommended under year 2020 base conditions. { YEAR 2020 BASE PLUS PROJECT CONDITIONS Intersections S.R.88/S.R.12/Jack Tone Road intersection— The recommended intersection widening improvements under year 2020 base conditions (in addition to the installation of a traffic signal recommended under Existing conditions)are projected to provide sufficient capacity to accommodate traffic demands under year 2020 base plus project"conditions. No additional mitigation measures are projected to become necessary under "year 2020 base plus project" conditions. With the year 2020 base improvements in place, "year 2020 base plus project" AM and PM peak hour LOS "C" operating conditions are projected. Based upon the project's contribution to PM peak hour traffic growth (of 200 vehicles) over "year 2020 base" traffic volumes (of 3,140 vehicles) at this intersection, the project's fair-share of cost of improvements at this intersection is estimated to be 2001(3140+200) = 6.0%. At an estimated cost of$200,000 for the year 2020 widening improvements at this intersection,the project's cost fair-share of year 2020 improvements is estimated to be $12,000. S.R.881S.R.I22randt Road intersection -- The installation of a traffic signal at this intersection as recommended under "Existing plus Approved Projects plus Project" conditions is projected to provide sufficient capacity to accominodate traffic demands through year 2020 base plus project conditions. No additional mitigation measures are projected to become necessary under "year 2020 base plus project" conditions. With the traffic signal in place under "year 2020 base plus project." conditions,AM and PM peak hour LOS "B" operating conditions are projected. Jack Tone Road/Brandt Road intersection_The installation of a traffic signal at this intersection and left- turn channelization for north-south approaches as recommended under year 2020 base conditions is projected to provide sufficient capacity to accommodate "year 2020 base plus project" traffic volumes. With the installation of a traffic signal at this intersection, "year 2020 base plus project" AM peak hour LOS "B" and PM peak hour LOS "C" operating conditions are projected. Based upon the project's contribution to PM peak hour traffic growth(of 105 vehicles) over "year 2020 base"traffic volumes(of 1,593 vehicles) at this intersection, the project's fair-share of cost of improvements at this intersection is estimated to be 1051(1593+105) =,6.2%. At an estimated cost of$150,000 for the installation of a traffic signal at this intersection and $100,000 for widening improvements, the project's cost fair-share is estimated to be $15,500.
