Although there are comparable weights to
each of the FHWA Standard Alphabets for Traffic Control Devices, the
use of ClearviewHwy may not be a seamless one-for-one replacement of
the existing typeface. The change from all uppercase to mixed case will
require interpretation of grid formats. Certain weights of ClearviewHwy
require slightly more word length and others less length when compared
to the respective FHWA font. A comparison is displayed in the “Compare
ClearviewHwy” section of this website and are based on a full
alphabet display. Word length comparison will vary slightly depending
on word configuration. All letterspaces for the FHWA series shown in
this comparison have been prepared letter-by-letter to comply with the
2000 charts. For Series B, C, and D, the FHWA uppercase is compared
to the mixed case ClearviewHwy. Note that the new letter space calculations
developed for the ClearviewHwy Type System includes more space than
the lowercase FHWA Series B, C, and D as specified in the 2000 SHS book.
This additional space is designed to aid word recognition and legibility
when viewed from the appropriate distance.
The following chart provides a general equivalence guideline between current
FHWA Standard Alphabets series and the ClearviewHwy Type System. |

ClearviewHwy font software was developed by the team that developed
the Clearview Type System that has received interim approval by
the Federal Highway Administration for use in road guide signs.
The renderings of every letter in every font are not only identical
to the published standard, but are the designs on which the FHWA
adoption is based.
The ClearviewHwy font software allows sign design engineers and
signs manufacturers to prepare precisely spaced layouts and cutting
files without having to reference separate spacing tables.
