CURRENT AND PROPOSED ORGANIZATIONAL ACTIVITIES
The Texas Legislature passed a law in 2005 that
required consolidation of certain data center related services for the largest
27 agencies, including TxDOT. The Texas information
technology (IT) oversight agency, the Department of Information Resources
(DIR), was charged was overseeing this consolidation. DIR chose to outsource data center
services. IBM signed the contract with
DIR in November 2006 to provide services beginning March 31, 2007. During the next several years, IBM plans to
migrate TxDOT’s servers to one of two state data centers.
Since IBM assumed responsibility for providing
services, TxDOT IT users have experienced a noticeable decrease in the
reliability of IT services. Many challenges remain to successfully migrate all
in-scope responsibilities to the service provider.
INFRASTRUCTURE (DESKTOP, NETWORKING,
TxDOT’s current server infrastructure includes an IBM
z-Series mainframe, eleven primary p-Series AIX servers, 593 Windows servers,
and 280 Novell servers. The department
supports more than 15,500 users, nearly 17,000 workstations, and 844
locations. The mainframe and four AIX
servers are located at the Texas State Data Center in San
Angelo, Texas. All other servers are located in the TxDOT
data center in Austin, in district and area
offices throughout the state, at the Austin
and at the Texas State
TxDOT currently uses Windows Server 2000 and 2003 and
the workstations use Windows XP. TxDOT will begin evaluating Windows Vista this
summer, but has no immediate plans to implement the OS.
TxDOT supports several database environments. ADABAS is
heavily used to support legacy Management Information Systems (MIS) applications
on the IBM Mainframe. Oracle and DB2 are used on AIX servers for GIS and
spatial data applications and Sybase is also used on AIX for the PeopleSoft
application. MS SQL is used to support
in-house developed applications and several purchased business
applications. Applications using Sybase
are being migrated to MS SQL or Oracle.
NEW SYSTEMS (JUST COMPLETED, IN PROGRESS, OR
PREPARING TO START)
MicroStation - TxDOT continues to support MicroStation
2004 Edition (V8) products for P. S. & E. submissions. TxDOT has deployed SELECT Server XM to
license and administer pre-XM products.
TxDOT is evaluating SELECT Server Athens, which provides numerous fixes
to known issues with the previous version.
TxDOT is working with Bentley on a Virtual Earth/MicroStation solution
to provide similar functionality used in the Google/MicroStation tools. TxDOT will evaluate the full line of XM
products and possible Athens
for possible future deployment.
TxDOT continues to support GEOPAK 2004 Edition (V8) for P. S. & E.
submissions. TxDOT has evaluated version
8.8 and is now evaluating 8.9 (XM).
TxDOT will also consider the Athens
release for evaluation when available.
TxDOT is engaged in several projects as proof of concept for automated
machine guidance. Bentley is making
Roadway Designer (from InRoads) part of the GEOPAK work flow to ease in the
creation of models for this purpose.
TxDOT continues to work with Bentley on testing of this new integration.
GPS - TxDOT currently has installed and implemented 90 GPS
base stations including 62 NGS recognized CORS sites. The stations are all
networked and centrally managed from Austin
through the Technology Services Division.
A subset of the network includes virtual reference stations. TxDOT has a
goal of expanding the network to provide coverage for surveying and
construction applications along the IH 35 and IH 69 Trans-Texas Corridor
routes. It is estimated that TxDOT will have 100 plus operational stations by
the end of this year.
Survey Data Management Systems (SDMS) - TxDOT is
currently using SDMS 3.5 with DOS collectors and version 4.3.1 with Windows CE
collectors. The standard format for
field data collection submitted is the SDMS format. TxDOT is also using SDMS
processor (version 2.0.1) which includes graphical chain editing and XML
CAiCE - TxDOT is currently using CAiCE Visual
Transportation V10 SP6 for surveying analysis.
TxDOT’s Standing Committee on Surveying (SCOS) has started a project, to
be completed June 2009, to evaluate software as a potential replacement for
GIS - TxDOT has implemented Main
Street Texas which is a web-enabled, GIS based information portal. The current implementation includes
applications for bridge inventory and inspection, right of way mapping, survey
monumentation, NGS control, and recycled roadway materials. In addition, TxDOT is testing integration of
pavement management mapping applications, Site Manager reports, HCRS links,
airport sites, and construction projects applications through Main Street
Bridge Geometry System (BGS) – TxDOT has implemented
BGS to replace the TxDOT Roadway Design System (RDS) as the primary tool for
bridge geometric design. The initial release BGS was developed by modifying RDS
to remove all program features that were not related to bridge geometry. As a
result, BGS is a scaled-down implementation of TxDOT RDS that focuses on bridge
LRFD / STD Precast Prestressed Concrete Girder Design and Analysis
Program (PSTRS-LRFD) - This project will provide TxDOT bridge
engineers and consultants with prestressed concrete bridge girder design and
analysis software that is compliant with the AASHTO Load and Resistance Factor
Design (LRFD) Specifications and with TxDOT design, analysis and construction
policies. TxDOT has hired a contractor and is working with the Washington State
Department of Transportation (WSDOT) in a joint development effort to modify
PGSuper, an open source program developed by WSDOT, to include the additional
functionality required by TxDOT. The upgraded program will be implemented to
replace TxDOT's current legacy application, PSTRS14. TxDOT continues to use
PSTRS14 as the primary tool. Many of the required PGSuper enhancements have
been completed and TxDOT has implemented version 2.0.5 within the organization
for production use with I-beams. The completion date is December 2008.
SiteManager – TxDOT’s current release of SiteManager is
version 3.8a. Version 3.8a contains the planned AASHTOWare enhancements as well
as TxDOT customizations for change orders and materials management, including a
solution for storing test template calculations.
Decision Support System (DSS) – TxDOT will use DSS 6.6b
to perform bid collusion detection and to provide analytical reports. The DSS
database will be used as a data warehouse for TxDOT construction projects. DSS 6.6b was placed into production status on
March 28, 2008. DSS 6.6b will run in parallel with the current DSS production
version (5.4c) until August 29, 2008. TxDOT support for version 5.4c will end
on September 1, 2008.
Electronic Bidding System (EBS) - The proposed system will
facilitate the electronic submission of construction and maintenance contract
bids. Submitted bids utilizing
electronic signature authority are secured in a third party electronic vault
and will only be accessible by TxDOT after the bid closing date. This system will directly connect to InSure
and Surety 2000, bonding agents. The
estimated completion date is the fourth quarter of 2008.
Electronic Project Records System (EPRS) – EPRS
allows contractors and sub-contractors to securely submit payrolls and other
documents over the Internet to a TxDOT database. The TxDOT database is used to
collect important data from contractors and to provide information to
record-keepers, auditors, and other governmental agencies such as the U.S.
Department of Labor and the Federal Highway Administration. TxDOT implemented version 1 in September
2007. Version 2 was delivered May 1, 2008, and version 3 is scheduled for late
PONTIS - TxDOT has created a customized PowerBuilder
front-end for the AASHTOWare PONTIS application. The front-end interface to
PONTIS was developed to support TxDOT requirements and to minimize the need to
customize the proprietary technical environment of the PONTIS application. The
TxDOT version of PONTIS is in production. The next major release is scheduled
for July 2008.
Storm Water Management System (SWMS) – This project
will implement a statewide storm water management system which will be used by
TxDOT staff and designated consultants to monitor, track and test storm water
runoff and any discharge of pollutants that might encroach on or near
department rights-of-way. The system will track data through a GPS data
collection application and store the data in a web-based geographical database
solution. The scheduled implementation date for SWMS is July 2008.
Permit Routing Optimization System (TxPROS) - This project will acquire
and integrate a software component into TxDOT’s existing Central Permit System
(CPS) to provide true automated routing for the transport of oversize and
overweight loads. The program will provide customers with a web-based, fully
self-service system that is compatible with TxDOT’s base GIS and bridge data
and will include required parameters such as structure height, lane width, load
ratings, one-way attributes, access roads, turn restrictions, and at-grade
railroad crossings. In 2007 a RFO was posted,
vendor proposals were evaluated, and the contract was awarded to ProMiles® Software
Development Corporation. The estimated completion date is December 2009.
Enterprise Document Technologies Implementation and Support
Project (EDTIS) – This project will implement electronic document
management technologies statewide in all TxDOT district and division
offices. The project is implementing
FileNet Content Services, FileNet Image Services, Altien Document Manager (a
web-based front-end), Kofax capture software and Adobe LiveCycle E-Forms
software. In addition, the project is also defining enterprise policies,
processes, and procedures, a standard enterprise access model and a publishing
model to facilitate universal document sharing across TxDOT. Currently all
district offices and most division offices have an electronic document management
system. The project will complete August
Information System (BIS) - TxDOT purchased COGNOS commercial
off-the-shelf (COTS) software to develop a new Budget Information System (BIS)
which includes both budget preparation and budget monitoring. Financial expenditures from a mainframe
ADABAS database are sent on a daily basis to update a client/server database
that allows end users in the districts and divisions to view five years worth
of budget reports. Budget adjustments, additional funding requests and
additional budget requests along with the corresponding approval of these
requests, are automated components of this system.
and Title System – Special Plates Integration -
The Special Plates Integration project integrated the Special Plates System
(SPS) into the Registration and Title System. This project supports one-step
processing of all new orders and renewals of special plates through RTS Point
of Sale workstations or over the Internet and provides special plate manufacturing
through RTS. The project was completed November 2007.
(AAH) - The program involves managing more than 3,800 volunteer groups who pick
up litter on TxDOT-maintained rights-of-way across the state. This project will replace the existing single
user desktop databases and manual program management methods with a web
interface to a central database to promote data sharing and increase
availability of program information to division administrators to facilitate
decision making and reduce duplication of effort among the district and
maintenance office coordinators. The
system will also include a GIS based map indentifying adopted roadway segments.
CAFM Explorer – This project
will implement enterprise facilities management software that assists
maintenance personnel with the management of work orders, preventative
maintenance plans, and warranties that deal with the upkeep of TxDOT buildings.
TxDOT evaluated products for internet filtering and reporting software and is
currently implementing Bluecoat.
– TxDOT has evaluated software solutions to provide a directory data
synchronization solution and selected the Novell Identity Manager. The
implementation is ongoing and will allow directory objects to be synchronized
across different directories, including NDS, GroupWise, Active Directory, and
PeopleSoft. This integration solution will reduce the administrative burden of
multiple directories, increase the overall accuracy of data and enforce data
LISTServ System – This system is being developed to allow the public to
subscribe and receive e-mails related to transportation topics.
RECORD OF EXCHANGE
TxDOT has obtained the
PGSuper source code and documentation from the Washington DOT (WSDOT) and is
currently working with WSDOT in an open source environment to modify the system
to meet TxDOT requirements. TxDOT has
also worked with several other states to share information and ideas on
document management, MicroStation, GEOPAK, GIS, and AASHTOWare.
