• Abstract:
  The objective of this implementation project was to implement four AWEGS across Texas at intersections ; appropriate for the installation of AWEGS. After a survey across Texas, four sites were chosen in the Atlanta ; District, Pharr District, Odessa District, `and San Antonio District. The AWEGS design plans were prepared ; for these four sites and submitted to the districts. These design plans were prepared for an intersection with ; high-speed approaches having the required dilemma zone detection design. The Atlanta District ; implementation was typical of the earlier implementation and used the TS-2 TS-1 conversion panel. ; However, the remaining implementations were configured for using enhanced BIUs. AWEGS software was ; also modified to account for rail preemption as the site in the Odessa District was being preempted by ; between 15 to 25 trains per day. Finally the implementation in the San Antonio District was redesigned to use ; radar detection for both dilemma zone and advance detection. AWEGS at the Atlanta, Pharr, San Antonio, ; and Odessa Districts have been implemented, and an evaluation of the system showed that AWEGS was ; performing satisfactorily at all sites.
