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

Driver Expectations Along a Corridor

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

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

Selected Consultants

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

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

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.
