UDOT’s not distracted

7 Comments, Uncategorized, by Catherine Higgins.

A new report shows that Utah is among states that are increasing efforts to stop distracted driving

Distracted driving includes many dangerous practices, including texting behind the wheel

Today the Governor’s Highway Safety Association released the first comprehensive study showing how states are enacting laws, developing public education programs and tracking accidents in order to halt distracted driving.

The Utah Department of Transportation (UDOT), in partnership with other agencies, has been fighting distracted driving using a variety of efforts, many of which are mentioned in the report.

“The furor over distracted driving as we know it came about with the availability and widespread use of cell phones in America. Ten years ago, if you were behind someone on the road who had trouble staying in their lane or swerving, you assumed they were driving drunk. Today, many people assume they are driving distracted,” states the report.

UDOT has collaborated with many agencies to fight distracted driving. Some of UDOT’s partners in the effort include the Utah Department of Public Safety, Utah Department of Health, local law enforcement, Utah Safety Council, AAA of Utah, Penna Powers Brian Haynes and others.  Some key Utah efforts mentioned in the report:

  • Distracted driving has been included in Utah’s  Strategic Highway Safety Plan since 2007
  • Utah has collected data on the number of crashes involving distraction of any kind as a contributing factor since 2002
  • Traditional media (television and print) and Social media (Twitter and Facebook) are used  by UDOT to educate the public about distracted driving
  • Educational efforts directed at teens, who are most likely to drive distracted, has been developed and presented in Utah schools

Additionally, the Utah Legislature recently enacted a law banning texting for all drivers.

IT’S UDOT, NOT THE FREEWAY FAIRY

No Comments, Uncategorized, by Catherine Higgins.

Have you recently driven along a familiar stretch of freeway that seemed to become smoother over night?

Concrete, not pixie dust: damaged pieces of I-15 are removed and replaced with new pre-cast panels.

If so, your now less-bumpy ride may not be a figment of your imagination. UDOT is improving sections of freeway while commuters sleep using new pre-cast concrete panels.

Damaged sections of freeway are cut out and replaced by new concrete.  The process is fast, produces great results and prolongs the life of the roadway.

First, the damaged area is measured and a slab is manufactured. Workers cut out the damaged area of pavement and prepare the base.

Holes for steel rebar are drilled in the existing concrete freeway. The new slab is placed, and grout is poured through holes in the top of the slab to hold the new piece of freeway in place. After only three hours, the new surface is ready for traffic.

Workers place a scrim as part of the process to prepare the base. Making sure the base is level is important. Any rocking or shifting could break the new panel.

This week, UDOT is placing pre-cast panels between Bountiful and Farmington, Utah. Hundreds of panels will be placed this summer.

A worker checks to make sure the base is the correct depth. The new panel is shown in the background. Slots in the new panel fit over steel rebar that reinforces the concrete panel through the tire path. Once the new panel is placed, grout is poured through the holes in the top.

Attention, walkers!

3 Comments, Uncategorized, by Catherine Higgins.

United States Transportation Secretary Ray LaHood recency blogged about distracted walkers who text, listen to music or talk on cell phones while crossing streets.   There’s no doubt, pedestrians who don’t pay attention pose a safety risk to themselves and others.

“And, it’s not just cars and trucks that pedestrians are ignoring,” writes LaHood. ” …Pedestrians distracted by cell phone calls and text messages also risk deadly encounters with the transit buses and commuter trains around them.”

The Federal Transit Administration is promoting Operation Lifesaver, a safety campaign that shows the dangers of distracted walking around trains.

Maybe we should have payed more attention in kindergarten. Remember the song “Stop, Look and Listen?”  Here’s a video to share with little walkers:

The Census collects information about population, which plays a fundamental part in predicting road use

Walt Steinvorth works in Transportation Planning at the Utah Department of Transportation. He doesn't wear a turban like the Great Carnack, but he does have an "all knowing" look about him, don't you think?

Walt Steinvorth calls himself  “the firm’s fortune teller” but he doesn’t use Tarot Cards or a crystal ball. Steinvorth depends on “a lot of science” to predict the number of vehicles expected to use an existing or future transportation facility using a traffic demand model or TDM. Census information is a fundamental ingredient of a TDM.

UDOT gets population numbers from demographers at the Governor’s office of Planning and Budget who look at historical trends, employment, birth and death rates to predict future population. Transportation planners use these population forecasts as inputs to the TDM to predict future highway and transit demand.

The Federal Government requires the departments of transportation and Metropolitan Planning Organizations (MPOs) to develop long range multi-modal transportation system plans for 20 years into the future. TDMs are used to determine where and when to expand highway and transit systems to meet future demand.

During long range transportation planning, UDOT and the MPOs uses a TDM to test various transportation alternatives. When planning future improvements for existing roads, a TDM is used to determine if more lanes are needed, and if so, how many. TDMs also provide information about pedestrian and bike use.

NOTE: UDOT is an ARE (acronym rich environment).  MPO and TDM are a few acronyms that see frequent use here at the DOT.  Click this link to see a list of other commonly used transportation acronyms. Then, impress your friends and family by using ATMS, LOS, or MUTCD with confidence. Your mom will be so proud.

A revised website has been launched for the Mountain View Corridor, a planned freeway, transit and trail system in western Salt Lake County and northwestern Utah County.  The site provides:

The project will be built in phases designed to balance transportation needs with available funds. Initial construction includes building two lanes in each direction with signalized intersections where future interchanges will be located.

In Salt Lake County construction has started on a 15-mile segment between 5400 South and Redwood Road (at approximately 16000 South). Construction will be completed in 2013.

In Utah County, the three-mile construction area is on 2100 North from Redwood Road to I-15. Construction will be completed in 2011.

Pioneer Crossing bridge move in October, 2009

While not as loud or colorful as an uber-famous rock band, a UDOT bridge move is a show worth catching. UDOT is, after all, a world leader in using new technology to replace bridges.

The public will be able to see that technology in action this weekend in American Fork when UDOT moves two segments of a new interchange from a staging area into place overnight on Friday June 4 and Sunday June 6 beginning at about 10:30 p.m. both nights.

The bridge move can be viewed from the existing Main Street Bridge both nights.  Parking will be available at the park-and-ride lot southwest of the interchange.  A flagger will be posted to help visitors enter the viewing area beginning at 9:30 p.m. Visitors will only be allowed to cross the freeway ramps to enter the viewing area at locations where a flagger is present.  Seating will not be provided.

The new segments should be in place sometime in the wee hours of the morning. Once in position, the  segments will form the north bridge of the new Diverging Diamond Interchange at American Fork Main Street.

What to expect

Watching a bridge move is an fascinating but slow process. Workers will be using a Self Propelled Modular Transporters (SPMT) which are multi-wheeled vehicles equip with lifts. The SPMTs are moved using a small box with controls that look like joy sticks. The bridge will be very carefully and slowly rolled into place over hours of time.

These segments are the among the longest and heaviest structures that UDOT has moved, according to Carmen Swanwick, Chief Structural Engineer at UDOT. Asked if those factors pose any difficulties, Carmen said “no, we’ve designed for it.” Engineers are uber-planners, after all.

For more information about Pioneer Crossing and the Diverging Diamond Interchange, please visit the Pioneer Crossing Web site or call the project information hotline at 1-877-222-3757.

i-Truck website and weekly email update gives trucker-specific road construction information

UDOT has a website and a weekly email update service that helps truckers and dispatchers anticipate or avoid road construction that may cause delay.

The Web site has an interactive map that allows users to view construction information by choosing a region or a specific project. To view the map, click this link to see the i-Truck website.

Building the Mountain View Corridor

No Comments, Uncategorized, by Catherine Higgins.

The Project Management Office for Copper Hills Constructors is located at 5680 Dannon Way, close to where construction will take place

Copper Hills Constructors has moved.  Two office buildings that house the 16-firm joint venture that is building  the Mountain View Corridor are now located on the corridor.

One of the two buildings Copper Hills Constructors will use was purchased by UDOT during the right-of-way aquisition process, and will be used for approximately a year before being removed to make way for the first phase of the Mountain View Corridor. The other building will be used for the duration of the project.

This building, located west of the Project Management Building, will be used for a year

Being close to where road construction will take place is very helpful and will make communication with stakeholders “go a lot more smoothly,” Says Teri Newell, UDOT Project Manager.
