r In KDA will evaluate existing traffic conditions and levels of service (.LOS) durFng the a. n. peak hour and-p.m. peak hour atA.4 intersections KDA will consult with San Joaquin Countyand the project applicant to identify the study;intersections The following is''a preliihina•ry list of potential study intersections x T k KDA proposes to collect infersection turning movemen# traffic volume count data attlie5e` intersections between 7.00 a m and 9.00 a m and between 4 00`p�m 'and 6,00 p m. rt However, in consultation with San Joaquin County and the,�.project ht he' may be shifted to.ensure an adequate assessment ofaeimpactsFof the-Project.= Existing LOS will be identified using the.methodologies described in°the Transportation Research M Board document Highway Capacity Manual 2060. KDA will evaluate the project-related impact of truck traffic`on the structural section of study roadway segments. As part of this-work,•KDA'will conduct�a windshield survey of the roads to general characterize the condition of each road. KDA will identify,improvements to each road that are already programmed and/or funded: This Work Plan does not include geo�- technical work, nor does it include.boring or cutting of roadways to determine the existing structural section. KDA will identify the near-term impacts, of project-related trips by evaluating traffic operations with project-related trips added to existing background traffic volumes_ Project- related significant impacts.will be clearly identified. KDA will qualitatively assess hazards 41 associated with project-related hauling of aggregate material. KDA will identify potential i locations of vehicle accidents,-and potential damage to non-project vehicles (e.g., damage to windshields). KDA will identify the long-term impacts of project-related trips by evaluating traffic operations with project-related trips added to,future Cumulative background traffic volumes. Project- related significant impacts will be clearly identified. KDA will forecast future year Cumulative background traffic volumes based on the last year of operation for the proposed project. Future year cumulative traffic volumes will, therefore, represent traffic conditions 15 years after the anticipated start of project,operation. KDA will assess available information sources for future year cumulative background traffic volumes. Potential sources of information include previous traffic studies. _Information sources may also include the Caltrans Statewide Travel Model and the San Joaquin Council of Governments (SJCOG) travel model. On each study roadway segment, KDA will employ the current truck percentage and the cumulative background traffic volume to estimate the total number of Equivalent Single Axle Loads (ESAt_s) occurring over the next twenty years without Project. KDA will also calculate the total ESALs with the addition of project traffic. The resulting ESAL values will be used to identify the Traffic Index (TI) on each study roadway segment. The general magnitude of truck impact will be described based on a potential impact to roads that are already in poor or fair conditions, as well as in terms of the relative change in Tl on each study roadway segment. KDA will note safety or capacity improvements needed to address project-related or cumulative impacts. While KDA does not propose to describe the nature of the actual structural improvements needed on each study roadway segment, KDA will note those locations where project-related traffic can be expected to cause the need for immediate repairs to roads that are in poor condition, as well as those locations where the project should contribute its fair share to the cost of improvements to be determined based on future engineering study.
