Data should be provided in 15 minute increments. The assumptions and/or variables used in estimating intersection volume/capacity ratios must be documented. If two different V/C ratios are involved at an intersection, use the statistics that demonstrate the strongest need and therefore correspond to be highest rank. RANK DEFINITION 3 1.30 or higher (Sliding scale to be used to rank projects with V/C ratio between 1.30 and .49. See below.) 0 .49 or lower If the proposed project has a V/C ratio lower than 1.30 but higher than .49, it will be evaluated and rated on a percentage basis. Each decrease of one one-hundredth from the V/C ratio of 1.30, will result in a decrease of .037 rating points. The rating points will be rounded to the third decimal place. The calculations are as follows: Let the proposed project V/C ratio = R Subtract R from 1.3, and multiply by 100. The result = D Multiply D x .037. The result = N Subtract N from 3.0 E.g. Proposed project has V/C ratio of 1.23; R = 1.23 1.3 - 1.23 = .07 x 100 = 7 D = 7 7 x .037 = .259 N = .259 3.0 - .259 = 2.741 The project receives 2.741 rating points for V/C The documentation to be submitted for the V/C ratio evaluation measure is: For segment projects: 1. The 24-hour ADTs for the area that the project covers 2. The existing number of lanes 3. V/C
