Trans 210.06(2)(a)(a) The department shall evaluate the existing and predicted traffic flow on the highway system that will be affected by the proposed major highway project. Traffic flow shall be measured using accepted engineering practices to compute the level of service on the highway system segments, and may consider traffic density, travel speed or time delayed and other related factors. Trans 210.06(2)(b)(b) Greater consideration shall be given to the severity of congestion and to the amount of traffic that is on the existing highway system segments that would be affected by the proposed major highway project. Trans 210.06(2)(c)(c) The calculation of the traffic flow measure points shall be based on a combination of the existing and predicted levels of service, weights for the levels of service and the number of existing and predicted 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 traffic flow measure points: Traffic Flow Measure Points =
å [ (LOS0 ) (W) (%HMVMT0 ) (2/3) ] +
å [ (LOS10) (W) (%HMVMT10) (1/3) ]
where:
LOS0 = the numeric value of the existing level of service on the highway segment.
LOS10 = the numeric value of level of service that is predicted to exist on the highway segment 10 years from the analysis year. The following table shows the numeric LOS values.
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)(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 =
å [ (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)
where:
Safety Points = the safety measure points for the proposed major highway project, as computed using procedures in par. (e).
Safety Pointsmax = the highest number of safety measure points given to any proposed major highway project under consideration for enumeration in that year, as computed using procedures in par. (e).
Trans 210.06 NoteNote: The crash rates and severity proportions are objective measures which are based on principles found in the Highway Safety Evaluation Procedural Guide, Docket No. FHWA-TS-81-219, published by the Federal Highway Administration. A copy of the Guide can be reviewed by writing or calling the Safety and Traffic Operations Engineer at the Federal Highway Administration, 567 D’Onofrio Drive, Madison, WI 53719, (608) 829-7519.
Trans 210.06(4)(a)(a) The department shall evaluate environmental considerations associated with the proposed major highway project through a draft environmental impact statement or environmental assessment. The draft environmental impact statement or environmental assessment shall provide summary information which shall be used to determine the potential net effects the proposed major highway project may have on environmental resources. Trans 210.06(4)(b)(b) The net environmental effects will be computed by comparing the potential effects of the build alternatives to the no build alternative. Trans 210.06(4)(c)(c) A proposed major highway project that will affect relatively more natural resources including, but not limited to, wetlands, uplands, flood plains, stream crossings and endangered species, shall be scored lower. Trans 210.06(4)(d)(d) A proposed major highway project that will affect relatively more physical resources including, but not limited to, air quality, sound quality, and contaminated sites, shall be scored lower. Trans 210.06(4)(e)(e) A proposed major highway project that will affect relatively more socio-economic resources including, but not limited to, agricultural land, park land, residential and business development, shall be scored lower. Trans 210.06(4)(f)(f) A proposed major highway project that will affect relatively more cultural resources including, but not limited to, historic properties and archeological sites, shall be scored lower. Trans 210.06 NoteNote: Environmental data will be collected from the environmental summary matrix provided in the draft environmental impact statement or the environmental assessment for specific impacts which apply to natural, physical, socio-economic and cultural resources.

Each measure shall have a maximum score of 100 points. The composite score shall have a maximum of 110 points. The following formula shall be used to determine the composite scores: Composite Score = 0 (10 + 1 economic measure score + 2 traffic flow measure score + 3 safety measure score + 4 environmental measure score + 5 community input measure score) where:
0 = 1 if the minimum requirements are met for either traffic flow or safety, or = 0 if the minimum requirements are not met for traffic flow and safety. 1 = weight for the economic measure which shall be .40 2 = weight for the traffic flow measure which shall be .20 3 = weight for the safety measure which shall be .20 4 = weight for the environmental measure which shall be .10 5 = weight for the community input measure which shall be .10 Trans 210.08(2)(2) Minimum allowable score.
