During the 1970s, the
University Group had become a leader in the then-new field of
microprocessor traffic monitoring: using portable, roadside electronics to
count, classify, weigh, and measure vehicle speeds automatically. Major
sponsors included the UK government's Transport and Road Research
Laboratory (TRRL) and private industry. In 1981, Dr. Davies developed a
portable weigh-in-motion (WIM) system for Arizona DOT which was
demonstrated on I-10 between Phoenix and Tucson. The resulting interest
led to significant FHWA funding for further work by the University
Research Group. |

Castle Rock's first contract
was the 1984 Heavy Vehicle Electronic License Plate (HELP) system
Feasibility Study, jointly funded by Arizona, Oregon and FHWA. This
initial work provided the foundation for the $25M HELP Program/Crescent
Project, a 10-year initiative that came to involve over 20 states.
HELP/Crescent gave direction to Commercial Vehicle areas of the U.S.
National ITS Program of the 1990s. The HELP pool-fund study retained CRC
each year as program management consultant, and many of its states remain
key CRC clients to this day. |
