W = weight applied to LOS numerical values, based on the following categories of LOS:

%HMVMT0 = hundred million vehicle miles traveled over the highway segment for the existing year divided by the hundred million vehicle miles traveled over the affected highway system for the existing year.
%HMVMT10 = hundred million vehicle miles predicted to occur over the highway segment in the 10th year from the analysis year, divided by the hundred million vehicle miles predicted to occur over the affected highway system in the 10th year from the analysis year.
Trans 210.06(2)(d)(d) The calculation of the traffic flow measure score shall be based on each proposed major highway project’s traffic flow points relative to the proposed major highway project with the highest number of traffic flow points. The following formula shall be used to determine the traffic flow measure score:
Traffic Flow Measure Score = (Traffic Flow Points/ Traffic Flow Pointsmax) (100)
where:
Traffic Flow Points = the traffic flow measure points for the proposed major highway project, as computed using procedures in sub. (2)(c).
Traffic Flow Pointsmax = the highest number of traffic flow measure points given to any proposed major highway project under consideration for enumeration in that year, as computed using procedures in sub. (2) (c).
Trans 210.06 NoteNote: Department engineers will use the procedures outlined in the general design consideration guidelines in Chapter 11, Section 5 of the Facilities Development Manual published by the Wisconsin Department of Transportation to determine the level of highway service. Copies of the manual may be obtained by writing to or calling the Division of Investment Management, Bureau of State Highway Programs, P. O. Box 7913, Room 933, Madison, WI 53707-7913, (608) 267-7715.
Trans 210.06(3)(3)Safety measure.
Trans 210.06(3)(a)(a) The department shall evaluate the number of crashes as well as the severity of the crashes that exist on the highway system affected by the proposed major highway project through:
Trans 210.06(3)(a)1.1. Determining the crash rate which shall be calculated by the total number of crashes divided by the number of hundred million vehicle miles traveled over the length of the highway system segments.
Trans 210.06(3)(a)2.2. Computing the severity proportion which shall be calculated by dividing the number of fatality and incapacitating injury crashes by the total crashes on the highway system segments.
Trans 210.06(3)(b)(b) Consideration shall be given to those crash rates and severity proportions that are significantly above the statewide average for similar highway types.
Trans 210.06(3)(c)(c) An evaluation of the number and severity of crashes shall include as many historical years as necessary to determine a reliable average.
Trans 210.06(3)(d)(d) An evaluation shall be made to determine if the proposed major highway project will affect the safety of pedestrians and bicyclists. A proposed project that will increase speeds on the existing highway without providing for improved pedestrian and bicyclists facilities will be scored lower.
Trans 210.06(3)(e)(e) The calculation of the safety measure points shall be based on the crash rate, severity proportion, and the hundred million vehicle miles traveled on the highway segments affected by the proposed major highway project. Points will be calculated for individual highway segments within the highway system affected by the major highway project. The total points for the major highway project is equal to the sum of the points for the highway segments. The following formula shall be used to determine the safety measure points:
Safety Measure Points =
  [ (CR + SP) (%HMVMT) (100) ] - P
where:
CR = the crash rate points given for crash rates that are significantly above the statewide average for similar highway types. The following table shows the points given for the categorical ranges of crash rates.

SP = the severity proportion points given for severity proportions that are significantly above the statewide average for similar highway types. The following table shows the points given for the categorical ranges of severity proportions.

%HMVMT = hundred million vehicle miles traveled over the highway segment for the existing year divided by the hundred million vehicle miles traveled over the affected highway system for the existing year.
P = 10 if the highway is currently used by pedestrians or bicycles, and will result in increased speeds on the existing facility without providing for improved bicycle and pedestrian facilities, or = 0 for those projects that are not used by bicycles and pedestrians, or will not result in increased speeds, or where improved bicycle and pedestrian facilities are planned.
Trans 210.06(3)(f)(f) The calculation of the safety measure score shall be based on each proposed major highway project’s safety measure points relative to the proposed major highway project with the highest number of safety points. The following formula shall be used to determine the safety measure score.
Safety Measure Score = (Safety Points/ Safety Pointsmax) (100)
