*126,033 is the average of the three components of Project Pegasus (TXDOTs methodology for determining the capacity ofProject Pegasus, see Trinity Matrix Summary Table 1).260,900 is the sum of the Canyon and Lower Stemmons (TXDOTs methodology for determining the capacity of two inter-dependent components Project Pegasus and the Trinity Toll Road, see Trinity Matrix Summary Table 2).

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.

9


10/26

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.

10


11/26

Full capacity improvements for Lowest

Stemmons (IH30 to DNT) cannot beattained unless Upper Stemmons (DNT

to SH 183) is also improved.

11


CONCLUSIONS NOT SUPPORTED BY DATA

Where is data or modeling to support this claim?


12/26

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.

12


INCONSISTENT CALCULATION FOR INCREASED VPD


13/26


HOW IS ADDED CAPACITY CALCULATED?

Total Vehicles Per Day is the SUM of the components:

TOTAL CAPACITY = COMPONENT A VPD + COMPONENT B VPD13


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.


PEGASUS ADDED VPD IS INCONSISTENT

14


15/26


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.


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.

Where is documentation that the NTTA willdefinitely fund project?

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

CANYON DETOUR COST INCREASE UNSUPPORTEDConstruction costs associated with

the Canyon will increase if the Trinity

Parkway is not available as an

alternate route during construction.

According to TXDOTs documents, Canyondetour cost is Not Available.


21/26

TXDOT documents: NO COST for detours for High Five, Central Expressway, and LBJ.

Costs for alternative route improvements for those projects included bettersignalization and improvements to parallel streets.

CANYON DETOUR COST INCREASE UNSUPPORTED

TXDOT Documents: No documents or data supports claim that Canyon drivers would use

Trinity Toll Road as detour during Canyon construction.

TXDOT Documents: No analysis of how many cars would use Trinity Toll Road as relieverroute during Canyon construction.

Pegasus adds 4 Managed Lanes, not 2


25/26

Where is the documentation for this recent review concluding

managed lanes are not feasible due to limited access to

downtown they provide?


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.
