  1. Project Development – High Priority Segments -- ATP 2 Road Surface? Gravel Paved 200 < ADT < 1,700 ADT < 200 ADT > 1,700 Segment received Stars for Lane Departure Crash Density & Critical Radius Curve Density 6” Latex Edge Line YES NO No Project Chevrons in Critical Radius Curves Noise Sensitive Receiver? NO NO YES YES Centerline Rumble Strip & 6” Wet Reflective in groove 6” Wet Reflective in groove Note: Except for gravel roads, corridor projects may also include Chevrons and paving 2’ shoulders in curves. * Where shoulder regradingnot required and up to an annual limit of 6 miles of paving. Beyond 6 miles per year of shoulder paving, wet reflective in a groove to be selected instead. Paved Shoulder? YES YES NO NO Centerline & Shoulder Rumble Strip Shoulder Rumble Strip Lane Width > 12 feet YES YES NO NO Centerline & Edge Line Rumble Strip Edge Line Rumble Strip 2 ft. Shoulder Paving, Safety Edge, and Shoulder Rumble Strip* Centerline Rumble Strip & 2 ft. Shoulder Paving, Safety Edge, and Shoulder Rumble Strip*

  2. Project Development – High Priority Segments -- Rural METRO Road Surface? Road Departure Project – Star Ranking Gravel Paved ADT < 600 ADT > 600 No Project 6” Latex Edge Line Noise Sensitive Receiver? NO YES Centerline Project – ADT 6” Wet Reflective in groove 3,000 < ADT < 8,000 Paved Shoulder? NO At Least One Severe Head-on or Sideswipe Opposing Crash YES NO Shoulder Rumble Strip YES Centerline Rumble Strip Access Density > 16 per mile Note: Corridor projects may also include Chevrons and paving 2’ shoulders in curves. * Where shoulder regradingnot required and up to an annual limit of 6 miles of paving. Beyond 6 miles per year of shoulder paving, wet reflective in a groove to be selected instead. ** At a limit of 6 total miles. Beyond 6 miles of 12-ft buffer, a 4-ft buffer to be selected instead. *** At a limit of 10 total miles. Beyond 10 miles of 4-ft buffer , centerline rumble strip to be selected instead. Lane Width > 12 feet NO YES YES NO Edge Line Rumble Strip 2 ft. Shoulder Paving, Safety Edge, and Shoulder Rumble Strip* 4-ft buffer with Centerline Rumble Strip*** 12-ft buffer with Left Turn Lanes**

  3. Project Development – High Priority Segments – Urban METRO Road Cross Section Two-Lane or Four-Lane Undivided Other 4-lane to 3-lane conversion or Reallocate road & shoulder width to convert 2-lane to 3-lane Consider access management during future reconstruction

  4. Project Development – High Priority Rural Intersections Road Surface? All Legs Paved Directional Median + Street Lights + Upgraded Signs & Markings Multiple Severe Right Angle AND Major>10,000 & Minor>4,000? NO Minor Legs Gravel YES All Legs Gravel PROJECT: Total ADT> 4,500 AND Minor ADT> 500 AND Right Angle Crash? Roundabout Note: On gravel approaches, install stop bar on paved apron YES NO PROJECT: CSAH ADT > TH ADT OR Major ADT ≈ Minor ADT? Street Lights Not Installed AND Minor ADT >200? Review for Sign Upgrade or Removal of Signs +Clear Sight Triangles YES NO NO YES Divided Roadway? PROJECT: PROJECT: PROJECT: YES NO Upgraded Signs & Markings Street Lights + Upgraded Signs & Markings Street Lights + All-Way Stop + Upgraded Signs & Markings PROJECT: PROJECT: Dynamic Mainline Warning + Street Lights + Upgraded Signs & Markings

  5. Project Development – High Priority Curves Three ways for a Curve to receive a project: Curves w/ Existing Chevrons High Priority Curves and those in close proximity PROJECT: All Curves on Roadways* Install/upgrade Chevrons +2’ Shoulder Paving +Rumble Strip High Priority Segments & Critical Curve Radius Note: Gravel roads were considered if the segment experienced a high frequency of severe curve-related crashes.

  6. Project Development – High Priority Ped/Bike Locations -- Urban Metro Corridor Focused (ADT, Lanes, Configuration, Speed) Intersection Type Signalized Unsignalized Countdown Timers? On Street Parking? YES NO YES NO Space available in median OR ability to reallocate space? Advanced Walk Pedestrian Countdown Timers & Advanced Walk Curb Extensions YES NO Raised Island Consider during future reconstruction

  7. Project Development – High Priority Right Angle Locations -- Urban Metro Corridor Focused (ADT, Configuration, Speed) Intersection Type Signalized Unsignalized Roundabout Confirmation Lights Multiple Severe Right Angle AND Major>10,000 & Minor>4,000? YES NO NO YES Spacing < Guidelines? Divided? Consider during future reconstruction NO YES NO YES Commercial? Right In/Right Out Directional Median
