Work Zone Safety Initiatives
The Work Zone Safety Working Group is made up of transportation professionals from the North Central Texas region.  The purpose of the working group is to investigate the use and effectiveness of strategies that could possibly reduce the number of fatalities and injuries that occur in work zones.  Possible strategies include: increased police enforcement, moveable barriers/alternative barriers, more informative signage, technology in work zones, protective trailers, portable stoplights vs. flaggers, speed limit modifications, worker visibility, public education, LED lights on signs, and no cell phones in work zones.  An analysis of crashes from 2007 that occurred in construction zones in Collin, Dallas, Denton, and Tarrant Counties was also performed.  More information on this initiative can be found on our Work Zone Safety Working Group web page.

Work Zone Safety Courses - Training Opportunities
These TxDOT grant-funded training opportunities are available for city and county employees through the UT Arlington, Division of Continuing Education, and are provided at no cost to the participants.  Available courses include: Work Zone Traffic Control/Qualified Flagger, Qualified Flagger/Work Zone Technician, Planning Work Zone Traffic Control, Night Road Work Planning & Implementation, and Installation & Maintenance of Signs and Pavement Markings.  More information on the courses can be found at www.uta.edu/ced [PDF]

ITE Web Seminars
The NCTCOG-hosted Institute of Transportation Engineers (ITE) Web Seminars are offered as part of NCTCOG's initiative to provide professional development opportunities to member agencies in the Dallas-Fort Worth region at no cost.  All ITE Web seminars will be scheduled based on pre-registered attendee interest.  A minimum of ten people must pre-register for the web seminar before it will be officially offered by NCTCOG, and pre-registration must be completed at least five business days before the scheduled web seminar. The seminar is a Power Point presentation viewed over the Internet. The audio portion of the presentation is heard via conference telephone.  The web seminars are eligible for PDH or IACED CEU.  For more information or to register for possible upcoming web seminars, contact Jill Hall .

TxDOT Traffic Records Assessment Questionnaire and Project
TxDOT conducted a Traffic Records Assessment Project.  The purpose was to gather information from city/county traffic engineers related to the current traffic safety data system.

Driver Safety Initiatives - Teens in the Driver Seat Program
NCTCOG continues to support the Teens in the Driver Seat (TDS) program.  The program has been undertaken by TxDOT (with the assistance of TTI).  FWTADS program is available to Texas schools at no cost.  The program focuses on five risky behaviors that include: driving at night, distractions, speeding, not wearing safety belts, and drinking and driving.  The first deployment in the North Texas area occurred in March 2007 in the Garland ISD.  The goal is to implement the program in additional schools in the North Texas area.  More information on the program can be found at www.t-driver.com

Safety and Red Light Running Cameras Inventory
According to the Insurance Institute for Highway Safety (2007), crashes caused by Texas drivers who run red lights are extremely costly to our economy and to human lives.  Motorists are more likely to be injured in urban crashes involving red light running than in other types of crashes.  As a result of these alarming statistics, the use of Red Light Cameras throughout the North Central Texas region is continuing to increase.  The purpose of the red light running cameras inventory is to collect detailed information on camera specifics and intersections, as well as information regarding the city’s policies and procedures for the operation of red light cameras; and to develop a regional database that will house this information, which will be made available on-line.  This information is currently being collected from cities around the region.

MUTCD and Texas MUTCD - Chapter 6I Working Group
The NCTCOG-sponsored Manual on Uniform Traffic Control Devices (MUTCD) Working Group was organized to review Chapter 6I of the draft Texas MUTCD and to develop and provide recommendations.  Chapter 6I of the MUTCD discusses control of traffic through traffic incident management areas.  The DFW region organized a MUTCD Subcommittee made up of local transportation professionals and emergency responders in the region.  As a result, the subcommittee felt the current incident classifications did not allow sufficient time to deploy the required equipment specified.  The recommendations were accepted by TxDOT during the development of the 2006 Texas MUTCD which became effective March 16, 2006.  The subcommittee also submitted the same recommendations to the Federal Highway Administration to be included in the upcoming edition of the Federal MUTCD.

School Zones Policy Task Force
The School Zones Policy Task Force is made up of transportation professionals, police representatives, and school district representatives from the North Central Texas region. One focus of the task force is to develop and prioritize a listing of issues related to operating, maintaining, evaluating, and enforcing school zones within the region and improving communications between school districts and transportation communities.  A future goal of the task force is to develop a best practices manual for school zones in the North Central Texas region and improve the overall safety and efficiency of our regional school zones.

HB 87 - 25 Miles Per Hour Speed Limit Technical Workshop
The purpose of the voluntary technical workshop on the newly adopted House Bill (HB) 87 was to assist in understanding and to educate members about HB 87.  HB 87 authorizes the governing body of a municipality to declare a lower speed limit of not less than 25 miles per hour, if the governing body determines that the prima facie speed limit on the highway is unreasonable or unsafe.  This bill applies to specific roadways.  HB 87 was successfully passed in the Texas Legislature in March 2005 and took effect immediately.  FWTAechnical Workshop on HB 87 gave an opportunity for our member cities to exchange information, ideas, and lessons learned as they related to the implementation of HB 87. Workshop presentations include:

Light-Emitting Diode Traffic Signal Replacement Program
The purpose of this program was to convert traditional incandescent traffic signal lamps to Light Emitting Diode (LED) lamps.  The replacement of traditional bulbs in traffic signals with LED lamps provides an energy savings opportunity to local governments that translates into a reduction of ozone precursor pollutants (such as Nitrogen Oxide (NOx) and Volatile Organic Compounds (VOC)) emitted from electric power generator plants in the region.  Local governments have confirmed positive experiences with conversions to this cost-effective alternative. LED technology has proven to be more reliable because of its increased life expectancy and reduced maintenance needs.  A subcommittee was set up to develop a strategy, conduct a survey, and help implement the program.  The Regional Transportation Council (RTC) adopted policy (May 2005) was to:  include LED lamps into existing and future Transportation Improvement Program (TIP) projects; and to include LED lamps in the Thoroughfare Assessment Program (TAP). More information on this initiative can be found on our LED Traffic Signal Replacement Program web page.

Vehicle Detector Repair Program
The purpose of the Vehicle Detector Repair Program is to allow vehicle detector repair as an eligible project under future funding initiatives (including the Thoroughfare Assessment Program).  Vehicle detectors are an integral part of nearly every modern traffic control system.  Current vehicle detection is based predominantly on inductive loop detectors installed in the roadway subsurface.  When properly installed and maintained, they can provide real-time data and a historical database against which to compare and evaluate more advanced detector systems.
