C. Base Roadway Network All roadways in the vicinity of the development shall be included as part of the TIA. Analysis of intersections or roadway segments not immediately adjacent to the development may be required by the District Engineer or Cabarrus County if significant site traffic could be expected to impact the intersection or roadway segment. If intersections impacted by the development are within a coordinated traffic signal system, then the entire traffic signal system shall be analyzed. However, if the. traffic signal system is large, a sub-section of the system may be analyzed if approved by the District Engineer and agreed upon by Cabarrus County. D. Safety Information The initial submittal may be required to include recent crash experience in the study area. Where proposed access points are in the vicinity of high crash locations or where safety may be impacted, additional safety studies may be required as part of the Traffic Impact Analysis. E. Traffic Volumes Traffic turning movement counts shall be taken at each existing intersection in the project area. Existing traffic counts may be used if taken within twelve months of the TIA submittal. At some intersections, counts older than one year may be used if adjusted to current year. The use of these older counts will be evaluated on a case-by-case basis by the NCDOT and Cabarrus County and shall be approved by the District Engineer or his or her agent. In general, AM and PM peak hour counts should be used. Other peak hour period counts, such as lunch and weekend periods, may be required if appropriate for the development. Counts shall not be taken on a holiday unless specifically needed for the particular analysis. The effects of school, seasonal variation and special event traffic shall be noted when appropriate. F. Traffic Capacity Analysis All capacity analysis shall be performed using methodology and software based on the Highway Capacity Manual procedures or as approved by the NCDOT District Engineer. All software shall be the latest version available unless otherwise approved by the District Engineer. If signalized intersections impacted by the project are within a coordinated traffic signal system, or may be included in a system because of changes to the network by the applicant, then they shall be analyzed as a system rather than as isolated intersections. Where available and appropriate, existing timing information shall be used. All analyses shall include level of service determination for the entire network and individual intersections and roadway segments, as appropriate. Intersection analyses shall include level of service determinations for all approaches and movements. Intersection analyses shall include queue analysis. G. Growth-to-Background Traffic Volumes Growth-to-background traffic volumes are factors of increases in annual traffic volumes generated outside the project area. These factors shall be applied to the existing traffic before adding any approved developments in the area. As deemed appropriate, the volume shall be compounded to the proposed build- out years or completion of development stages. In general, these factors will be determined from local or statewide data. . H. Approved Development Traffic Approved development traffic is defmed as traffic generated by all developments approved by local jurisdictions or submitted to local jurisdictions for approval within the development vicinity at the time of the TIA submittal. I. Background Analysis Background (no build) analysis shall include existing traffic, traffic signal phasing and timing, background growth, and all approved developments. The analysis shall take into consideration any impi'Ovements to the roadway network that will be in place by the bnild-out year, or staged build-out in development, as appropriate. An analysis shall be performed for each staged build-out year as necessary. 1ms analysis shall be performed for the proposed build-out year of the development or other year as identified by Cabarrus County or NCDOT and approved by the District Engineer. /:;--/ (a.)
