| ClearviewHwy was designed for optimal legibility
and has a different visual structure than the FHWA Highway Gothic
Series. In general, the ClearviewHwy lowercase is taller, interior
shapes of letters are more open to allow clear definition of each
letter, and letterspacing has been designed to accommodate the
needs of older drivers when used with both regular and high brightness
sheeting materials. Other features designed to enhance word contrast
include (Figure 1) capital letters B, D, P, and R that break the
top of the line. The lower case letters are drawn to afford clear
definition to letterforms when viewed from a distance. The ascenders
of; b, d, f, h, i, j, k, and l of lowercase letters extend above
the top of the initial capital letter to enhance word contrast.
The descending lowercase letters, including the lowercase “g,” have
been designed with the main loop placed above the baseline to allow
full definition of the descending tail. All of these nuances are
inherent to the design, and to each respective typeface in the
ClearviewHwy Type System. |

Use of ClearviewHwy is intended for mixed case
applications. The new ClearviewHwy Type System is provided in six
weights (Figure 2). Each weight is specified with two versions:
one for use in positive contrast applications (light letter on
a dark background), and one for use in negative contrast applications
(dark letter on a light background). The negative contrast version
is optically adjusted to appear the same weight as the positive
contrast version, but has a slightly heavier stroke width. |

over bifurcated lanes that require significantly greater legibility distance
without increasing capital letter height. |
