Presentation Outline



Overview of Intelligent Transportation
Systems (ITS) in TxDOT
Border Safety Inspection Facilities (BSIF)
Commercial Vehicle Information Systems
and Networks (CVISN)
Intelligent Transportation
Systems




The application of advanced technologies
(computers, communications, electronics) to
transportation problems
Congestion, incidents, safety, weather
Multiple technologies
Field equipment in harsh environments
The Need for ITS




Traffic volumes continue to increase
New construction is not keeping up
Impossible to simply “build our way” out of
congestion
Transportation Management Centers (TMCs)
can help ease congestion on the existing
highway system
Benefits of
Effective ITS


Reductions in:
– Motorist delay and queue length
– Direct and indirect economic losses
– Air pollution
– Incident response times
– Secondary collisions
A more efficient transportation system
Transportation Management
Centers (TMCs)




TxDOT has 9 TMCs in operation
Large centers: Houston TranStar, 200 mi. of
freeways, multiple agencies, large building,
large operations floor
Small centers: Wichita Falls, a few cameras
and signs, weather data, 2 workstations,
part-time operator
TMCs operating in Laredo and El Paso

TMC Applications





Incident detection and management
Traveler information
Monitor system performance
Safety
Weather
Hurricane Rita Evacuation
ITS Field Equipment



Dynamic Message Signs (DMS)
Closed Circuit Television Cameras (CCTV)
Detection (multiple technologies)
Lane Control Signals
Environmental Sensors
Highway Advisory Radio (HAR)
Fiber backbone in urban areas; large
communications systems
Leased wireline (ISDN, T1); Wireless
TxDOT ITS Program







$40M to $50M ITS projects let per year
$10M to $15M per year on maintenance,
upgrades, and rehabilitation
700 miles of highways with freeway systems
395 DMS
Over 800 closed circuit ITS cameras
100 miles of HOV lane systems
Over 700 miles of fiber optic cable backbone
Traffic Websites


Allow motorists to get
information from their
computer
Websites can provide:
– Interactive maps of
current conditions
– Camera snapshots
– Incident locations
– DMS display information
– Travel times
– Text messages
Rural ITS







Flood warning
Ice, winter weather
Fog
Traveler, tourist information
Alternate routes
Remote CCTV at strategic locations
Future: corridor information (I35, I40, I10)
Need for Rural ITS
•Why?
•80 % of Nations roads are in rural & small urban
areas (under 50,000 population)
•Rural roads < 40% annual vehicle miles, but > 60%
traffic fatalities
•Work zone fatalities on non-Interstate roads 3 times
higher
•Average twice as long for crash notification and
victim transfer
Statewide Development and
Integration (SDI) Program









Standard statewide software modules (TMC)
- realistically 80%
Write once, use many times
Reduce lifetime maintenance costs
Well documented, defined interfaces
System Engineering process
National standards
Software modules are in operation
BSIF software developed by SDI contractor
Southwest Research Institute (contractor)
Signal for complex intersection
Border Safety Inspection
Facilities (BSIF)






8 locations planned at border crossings
Standard design
2 in El Paso under construction
Operated by DPS
Very automated process (eventually)
Standard software modules; write once, use
many times
BSIF Equipment







DMS
Detection
Transponder readers
Cameras (surveillance and snapshot)
Oversize detection
Weigh-in-Motion
Static scales
Facility Layout
WIM
Visual Inspection
Current development activities



Development underway for BOTA (El Paso)
– Flow management, DMS, CCTV, RFID tags,
presence detection, weigh-in-motion, scales,
dimensional checks
– Interface with DPS safety information
Reuse of software
– Existing statewide ITS subsystems
– BSIF modules to be developed and shared
Subsequent deployments under review:
– Zaragoza (El Paso)
– Eagle Pass (Laredo)
Border Wildlife
Commercial Vehicle Information
Systems and Networks (CVISN)






Multiple agencies sharing data
TxDOT, DPS, Comptroller
Common CVISN data base
Single point of contact, electronic
Completed top level design and business
plan
Working group and steering committee
established
CVISN…





The collection of information systems and
communications networks that support CVO.
Includes information systems owned and operated by
governments, motor carriers, and other stakeholders.
Provides a framework for parties engaged in CVO
safety assurance and regulation to exchange
information and conduct business transactions
electronically.
The goal is to improve the safety and efficiency of
commercial vehicle operations.
Core Compliance includes: Safety Information
Exchange, E-Credentialing, E-Screening.
CVISN – Planned TX
Architecture
CVISN Status

Summary
– Participants (DPS, CPA, and TxDOT) will share
safety and credentialing data via TexVIEW
– Motor carriers will be able to apply for and
renew credentials online
– Working group meeting of participants to
determine status is being planned.
– TexVIEW and One-Stop need to be developed.
– Once developed, existing systems will be
modified to tie into these new systems
– BSIF will utilize CVISN data for safety inspections
Questions or Comments?

Good judgment comes from bad experience,
and a lot of that comes from bad judgment
