TRINITY TOLL ROAD vs. PROJECT PEGASUS
CONFLICT BETWEEN DATA AND NARRATIVE
Narrative and Trinity Matrix Summary are
misleading, conflict with TXDOTs data, andreveal a bias in favor of the Trinity Toll Road
that is not supported by TXDOTs documents.

FLAWS IN MATRIX SUMMARY
WRONG SCENARIO USEDCant compare projects using
Both Built scenario.
Cannot determine which project BY ITSELF moves more cars for less money if we
use figures that assume BOTH projects are built.
Using Both Built scenario minimizes Project Pegasus positive effects on traffic,which are superior to Trinitys.
Should compare Trinity Only scenario to Pegasus Only scenario to properlycompare projects.

Full capacity improvements for Lowest
Stemmons (IH30 to DNT) cannot beattained unless Upper Stemmons (DNT
to SH 183) is also improved.

Where is data or modeling to support this claim?

This significantly understates Pegasus added
Vehicles Per Day and is not calculated the
same way as the Trinitys added VPD.
Trinity Parkway provides 132,000
additional vpd and Pegasus
provides 93,300 additional vpd.

FLAWS IN MATRIX SUMMARY
INCONSISTENT CALCULATION FOR INCREASED VPD
-
7/31/2019 Powerpoint for Mayor Rev4
13/26
FLAWS IN MATRIX SUMMARY
HOW IS ADDED CAPACITY CALCULATED?
Total Vehicles Per Day is the SUM of the components:
TOTAL CAPACITY = COMPONENT A VPD + COMPONENT B VPD13
-
7/31/2019 Powerpoint for Mayor Rev4
14/26
For Project Pegasus, however, TOTAL VPD is calculated by AVERAGING the components:
DITTO
DITTODITTO
This error SIGNIFICANTLY REDUCES TOTAL Vehicles Per Day for
Project Pegasus, comparing unfavorably to the Trinity Toll Road.
FLAWS IN MATRIX SUMMARY
PEGASUS ADDED VPD IS INCONSISTENT
14
-
7/31/2019 Powerpoint for Mayor Rev4
15/26
FLAWS IN MATRIX SUMMARY
ADDED VPD SHOULD BE CALCULATED USING
REAL TRAFFIC, NOT HYPOTHETICAL CAPACITY
15
This erroneous calculation for Added Vehicles Per Day benefits the Trinity Toll Road since
its CAPACITY is greater than the REAL TRAFFIC it will move (132,000 vs. 114,000).

16/26
Use PROJECT PEGASUS ONLY build scenario versus TRINITY TOLL ROAD ONLY
build scenario.
FLAWS IN MATRIX SUMMARY
HOW TO CALCULATE ACCURATE ADDED VPD
16
To correctly compare the increase in vehicles per day for Pegasusand the Trinity, we must:
Calculate VPD using SUM methodology instead ofAVERAGING components.
Use REAL TRAFFIC figures, not hypothetical CAPACITY.

According to TXDOTs documents, TrinityToll Road funding is TBD.
The Trinity Parkway has a
significant funding source (toll
revenue) to help support the project.

How much money is significant andwhere are documents to support this?

Where is the documentation for this recent review concluding
managed lanes are not feasible due to limited access to
downtown they provide?
FLAWS IN MATRIX SUMMARY
MANAGED LANES SUDDENLY NOT FEASIBLE?
According to Trinity SDEIS,only 1 out of 5 cars is
traveling TO downtown.
4 out of 5 cars are travelingTHROUGH downtown
80% of cars on the Pegasussystem could use
managed/tolled lanes.

CONFLICT BETWEEN DATA AND NARRATIVE
Given the significant discrepancies between
TXDOTs data and the narrative, an outside,independent analysis should be conducted.
