Efland-Buckhorn-Mebane Access Management Plan Implementation of the future roadway network and recommended cross sections is intended to occur over time and largely through the development approval process. Developers are required to dedicate right-of-way consistent with the recommended cross sections and construct roads in accordance with NCDOT Roadway Design Manual requirements. While the cross sections are designed for local and collector roads, their capacity is taken into account as intersections are also analyzed and recommendations are provided in an effort to address traffic impact. atersection Improvement Requirements and TIE Evaluating LOS determines the necessary recommendations at various intersections in the planning area. For reference, many municipal governments adopt policies like TIAs that require that new development not decrease LOS below level C or D. Determining the LOS for a given roadway involves complex calculations taking into account factors such as roadway grades and lane width. The 2017 Transportation Study identified the following intersections as those requiring specific improvements by developers and any transportation projects associated with them (TABLE 4). The 2017 Transportation Study serves as an overall Traffic Impact Analysis (TIA) for the E-B-M area, as each pod's development potential was modeled in accordance with Section 6:17 - Traffic Impact Analysis — of the County's UDO. The purpose of a TIA is to "insure that proposed developments do not adversely affect the highway network and to identify any traffic problems associated with access from the site to the existing transportation network." TIAs also document the required traffic mitigations that must be incorporated into the proposed development. A TIA is required for all special use permits, subdivisions, conditional zoning applications and site plans. This is for all applications with an estimated trip generation exceeding 800 daily trips as the pods have previously demonstrated.

Advances in ITS may also be implemented at various intersections to help improve safety and mobility. Some of these advancements include but are not limited to: • Curve Speed, Work Zone, and Do Not Pass Warnings Orange County Planning Department Page 21
