| The ClearviewHwy Type System for traffic
control devices was developed by a design team that included Donald
Meeker and Christopher O’Hara of Meeker & Associates,
Inc., James Montalbano of Terminal Design, Inc., Martin Pietrucha,
Ph.D., and Philip Garvey of the Pennsylvania Transportation Institute
(PTI), with supporting research by Gene Hawkins, Ph.D., and Paul

on experimental design was provided by Susan T. Chrysler, Ph.D.,
formerly with the 3M Company and now with TTI. This type system
is designed for signing all streets, highways, and other byways
open to public travel.
