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.
