ACTC’s methodology is based on volume- <br />to-capacity (v/c) ratios while CCTA evaluates arterials based on intersection level of service. This <br />analysis was evaluated based on the ACTC methodology given the nature of the analysis <br />requirements. During the design phase of a project, it is anticipated that more detailed operational <br />analysis will be completed. <br />Arterial level of service analysis assumed a per-lane capacity of 800 vehicles per hour.
