The specific criteria that were used to prepare the ClearviewHwy
Type System for inclusion into the Manual on Uniform Traffic Control Devices.
| 1. |
Create a replacement for E-modified that has increased legibility and ease of
recognition with reduced halation for older drivers when placed on high brightness
sheeting materials. |
|
|
| |
|
|
| |
|
| 2. |
Create mixed case alternatives to Series B, C, D, E, and F with greater legibility
and ease of recognition at the same size as all uppercase Standard Highway Alphabet
displays. This would be a typographic system based on mixed case applications. |
|
|
| |
|
|
| |
|
| 3. |
Build on the basic Standard Alphabet hierarchy of six weights with optimized
letterform design for increased legibility and recognition for older drivers.
Including versions of each weight for use in both positive and negative contrast
to address the problems of overglow on guide signs and equally solve the problems
of reduced stroke width and readability of negative contrast regulatory and warning
applications. |
|
|
| |
|
|
| |
|
| 4. |
Develop a method of manual spacing using both metric and English systems of measurement
that is compatible with the method proposed for FHWA Standard Alphabets as specified
in the 2000 Standard Highway Signs book. |
|
|
| |
|
|
| |
|
| 5. |
Provide in proportionally scalable electronic version for uniform spacing for
all weights of the type in the system using industry standard software, with
spacing values and kerning that optimizes legibility of the letterforms at the
intended viewing distance. |
|
|
| |
|
| 6. |
Provide font applications software for the ClearviewHwy Type System which would
be adaptable to a broad range of software applications commonly used in engineering
departments and sign shops for standard highway sign design and production. |
