1 Jason J. Siwula, PE – Safety Engineer HSIP HORIZONTAL ALIGNMENT SIGNING

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

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 Signing2009 MUTCD Signing Update

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

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

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 (1 st 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.
