Cable median barriers: A cost-effective means to save lives


From Michigan Department of Transportation

CAR-Fatal-crashes-TZD-bannerMedian-crossover crashes are among the most hazardous events that can occur on freeways, often leading to serious injury or death. In recent years, high-tension cable median barriers have emerged as a cost-effective alternative to conventional barriers in preventing such crashes. The Michigan Department of Transportation (MDOT) began installing them on state freeways in 2008. A recently completed research project confirmed that cable median barriers are effective at reducing crossover crashes and improving freeway safety in Michigan, produced guidelines to help identify the best locations to install them, and developed content for public outreach materials explaining their benefit.

After the barriers were installed, crossover crash rates on those highway segments fell by 87 percent, and the barriers successfully contained 97 percent of the vehicles that hit them. Cable barriers have improved overall safety at the locations where they have been installed. The most serious crash types—fatal and severe injury crashes—decreased by 33 percent after cable median barriers were installed, according to rigorous statistical analysis. Since their installation, cable barriers are estimated to have saved 20 lives and prevented over 100 serious injuries in Michigan.

The research study confirms that cable median barriers are a cost-effective treatment for reducing crossover crashes, fatalities and serious injuries in Michigan. The guidelines developed will give MDOT a framework for determining where cable barriers are likely to have the greatest positive impact and return on investment based on crash data and site characteristics specific to Michigan. MDOT is reviewing these recommendations for possible incorporation into future updates to the department’s median treatment design guidelines.

To help educate drivers about the safety benefits of cable median barriers, the researchers also developed content for public outreach messaging, including an update to MDOT’s 2011 brochure on cable median barriers. For a copy f the new brochure go to http://www.michigan.gov/documents/mdot/MDOT_GuardrailSystemBrochure_300385_7.pdf

The statewide goal is to reduce traffic fatalities and serious injuries on all roadways from 889 and 5,706 respectively in 2011, to 750 and 4,800 in 2016. The mission is Toward Zero Deaths on Michigan Roadways. Visit www.michigan.gov/zerodeaths for more informaiton.

MDOT looking for Grand road watchers during wintry commutes


The Michigan Department of Transportation (MDOT) is seeking “Road Watchers” to report on winter highway conditions in MDOT’s Grand Region, which includes: Ionia, Kent, Montcalm, Muskegon, and Ottawa counties. MDOT is recruiting volunteers who travel on US, M and I routes in these counties to help measure how well the roadways are maintained following winter storms. Comments gathered will be used to improve winter maintenance. MDOT is looking for “Road Watchers” to monitor the following highways during morning commutes:
*N-Road watchers

  • I-96 throughout Kent and Ionia counties
  • I-96 from US-31 to the Ottawa/Kent county line (Muskegon and Ottawa counties)
  • US-131 throughout Kent County
  • I-196 throughout Kent and Ottawa counties
  • M-57 from US-131 to M-91 in Greenville (Kent and Montcalm counties)
  • M-37/M-44 (East Beltline/Broadmoor avenues) from Caledonia to West River Drive/Cannonsburg Road (Kent County)
  • US-31 from Jackson Avenue in Grand Haven to I-96 (Ottawa and Muskegon counties)

“We receive so much valuable information from motorists each winter that we wanted to make it official and encourage more,” said MDOT Grand Region Associate Engineer for Operations Tim Little. “This area is notorious for lake-effect snow and we’ll use all the data we can to improve our winter maintenance efforts. We hope many travelers will volunteer and share their commuting experiences.”

MDOT will compile the survey results to track winter highway conditions with the goal of improving winter maintenance practices and response times. Surveys should only take a few moments to complete.

Road Watchers are polled randomly for each storm event and asked to participate in an online Survey Monkey survey about the road conditions they encountered. All results will be anonymous. To volunteer, visit www.michigan.gov/roadwatchers.

MDOT reminds motorists and bicyclists to share the road

CAR-Fast-FactsCAR-motorists-and-bicyclistsThe Michigan Department of Transportation (MDOT) wants to remind motorists and bicyclists alike to be courteous and share the road.

Schools are now in session, but that doesn’t mean the bicycling season is over. Many people are riding bicycles, either individually or in groups, taking in the fall colors on scenic roadways or shopping for farm fresh produce at roadside stands. Motorists are reminded that bicyclists are legal users of the roadway and groups of bicyclists are legally allowed to ride on the roadway without special event permits or accommodations, while following all applicable laws.

In early 2014, MDOT and the Michigan Department of State (MDOS) released a “share the road” video, showing the wide range of bicyclists everyone must share the road with. It features cameo appearances by State Transportation Director Kirk T. Steudle and Secretary of State Ruth Johnson, who remind bicyclists to follow the rules of the road, and motorists to pass bicyclists at a safe distance.

A recently released report on the economic benefits of bicycling estimated that organized bicycle events and bicycle-related vacations contribute $38 million to the Michigan economy. These organized group events are important contributors to our communities and states economy.

MDOT reminds drivers: Lives are in your hands – always pass cyclists at a safe distance.

MDOT warns motorists, private plows of winter hazards

CAR-Fast-FactsA private snowplow pushes snow into a state highway, causing a public plow to crash and roll over, injuring the driver. Meanwhile, in another area a motorist disregards winter conditions, traveling too fast and crashes into the rear of a Michigan Department of Transportation (MDOT) plow, disabling it.

Those are just two cases of hazardous actions in winter resulting in crashes earlier this month in Michigan, and in both cases taking two winter maintenance vehicles out of commission.

“Slippery roads, reduced visibility, and excessive speeds greatly reduce the margin of error in winter driving,” said State Transportation Director Kirk T. Steudle. “We implore private plow operators and motorists to be extra cautious, and avoid doing anything that adds to the hazards of winter driving or roadway maintenance.”

Two main concerns are when residents and businesses pile snow at the ends of driveways along the highway shoulder, and when snow is pushed across the road, leaving snow or slush on the road surface.

The Michigan Vehicle Code prohibits depositing “snow, ice, or slush on any roadway or highway,” and “the obstruction of safety vision by removal or deposit of snow, ice, or slush.” This includes the end of driveways, where banked snow can reduce visibility for vehicles trying to enter the roadway. Leaving a trail of snow on the pavement while plowing across the road also can create an added hazard to unsuspecting motorists and to road maintenance personnel.

Motorists also should be particularly careful around winter maintenance snowplows and salt trucks. These large, powerful vehicles may be traveling at slower speeds than vehicles around them, and may be obscured by blowing snow.

“For your safety and the safety of our operators, it’s important to give snowplows a buffer to do their work,” Steudle said.

Some tips for motorists encountering snowplows:

• Snowplows have limited visibility and drivers cannot see directly behind their trucks;

• Snowplows often throw up clouds of snow behind them, reducing visibility for drivers following behind them;

• Motorists should never attempt to pass a moving snowplow on the right. With new wing plows and tow plows, the blade can clear the shoulder and the lane of travel simultaneously. Motorists attempting an illegal pass through a snow cloud on the right and/or shoulder of the road most likely won’t see the plow blade and run the risk of a serious crash; and

• MDOT snowplows throughout Michigan will be driving at 25 mph when applying salt, which helps keep more salt on the roadway driving lanes where it is most effective. Snowplows may travel at up to 45 mph when plowing only.

MDOT says: Drive like you want to make it home tonight.

Extra enforcement for ticketing aggressive cars and trucks


December 2-13


Officers from six law enforcement agencies will conduct Ticketing Aggressive Cars and Trucks (TACT) program enforcement on U.S. 131 and I-196 in Kent and Ottawa counties December 2-13. They will look for violations by both passenger vehicle and truck drivers, such as improper lane use, careless and reckless driving, speeding, following too close and failure to yield the right of way.

During this time, Michigan Department of Transportation (MDOT) freeway message boards in West Michigan will feature a reminder to Leave More Space for Trucks.

“Michigan motorists regularly check MDOT freeway message boards for drive times, road closures and traffic updates. For the next two weeks, West Michigan drivers will also see a truck safety message,” said Michael L. Prince, director of the Michigan Office of Highway Safety Planning (OHSP). “The public information and enforcement activities are part of our efforts to reduce truck-involved crashes and fatalities.”

Passenger vehicle drivers can reduce their risk of being involved in a crash with a large truck by:

•  Allowing one car length for every 10 miles of speed when changing lanes in front of a truck.

•  Maintaining speed when passing to avoid driving in blind spots.

•  Avoiding tailgating.

•  Allowing large trucks plenty of room when entering the highway or merging with traffic.

The TACT program combines outreach, education and evaluation with enforcement efforts to promote safe driving around trucks and reduce the number of truck-related traffic crashes, fatalities and serious injuries.  OHSP is supporting the TACT program with funds from the Federal Motor Carrier Safety Administration and the Michigan Truck Safety Commission dedicated for this purpose. This is the first time this type of program has been conducted in Michigan.

The participating agencies include the Michigan State Police, Kent and Ottawa county sheriff offices and Grand Rapids, Walker and Wyoming police departments. TACT program patrols are in addition to regularly scheduled shifts.

Notices about traffic updates, road closures and drive times take precedence on MDOT freeway message boards.  Leave More Space for Trucks will be displayed when there are no other priority messages.

This project is part of Michigan’s Strategic Highway Safety Plan signed by Gov. Rick Snyder in February.
