  1. Hsip horizontal alignment signing Jason J. Siwula, PE – Safety Engineer

  2. Horizontal Alignment Signing Initiative • Systemic Approach to installing Horizontal Alignment Signage (HAS) • Install HAS utilizing fluorescent yellow sheeting along the entire corridor where one RD Plan “enhanced” curve is located for consistency and uniformity • Target approximately 25% of the state maintained system over the five year implementation schedule

  3. HSIP Signage Corridors

  4. Why Horizontal Alignment Signs? • Reduction in Lane Departure crashes • 2009 MUTCD Signing Changes • 2009 MUTCD Compliance Date • Driver expectation • Benefit / Cost

  6. Examples of Signage Updates Previously Existing Signing 2009 MUTCD Signing Update

  7. MUTCD Compliance Date – December 31, 2019 Many of the 2009 MUTCD Compliance Dates have been revised or eliminated, however, the compliance date for Horizontal Alignment Signing remains in place.

  15. Benefit / Cost Ratio between 8.6-102.3 Bottom line – Many sites can be implemented with a relatively low cost for a significant benefit! *B/C Source: FHWA-HRT-09-045

  16. A New Approach • Contract with a consultant to supplement Traffic Engineering functions • Ball Bank Indications • Setting of advisory speeds • Approximate sign placement • Quantities for letting projects

  17. Selected Consultants

  18. Example Signing Layouts Non-Enhanced Curves or Turns Enhanced Curves or Turns

  19. Current Status • Contracts with all consultants have been authorized 11/26/2012 • Horizontal Alignment Signing / Ball Bank Training Class (1st scheduled for December 18, 2012) • “Boots on the ground” starting near the first of the year

  20. Next Steps • Review initial corridor submissions from each consultant • Meet with the Districts to discuss implementation through the Construction Procurement process (inspection, quality control, etc.) • Let construction contract(s) for several corridors to ensure the quality of the end product • Adjust the process as necessary for implementation and complete Phase 1 and Phase 2.
