Alternative Funding for Work Zone ITS Fact Sheet

Nearly everyone who understands work zone ITS knows it is a cost-effective way of mitigating the traffic impacts of major and sometimes even minor road construction projects. Studies have proven the value of these systems. But DOTs will often tell you they don’t have the funding to pay for it.  The FHWA encourages states to use work zone ITS. They will pay for these systems through conventional construction funding. So, when states say they don’t have the funding they mean they haven’t found a pot of money outside of the money they use for asphalt and concrete.

FHWA wants to address that problem. They have just published the “Alternative Funding for Work Zone ITS Fact Sheet”. In it they document how Illinois uses HSIP funds to pay for Work Zone ITS. Download a copy of the fact sheet HERE.

FHWA says this is a highly underutilized funding mechanism. According to the fact sheet, “While some states use HSIP funds for work zone purposes, many state DOTs do not tap into this resource. Out of the more than 4,000 HSIP projects referenced in the 2016 HSIP National Summary Report, only 13 were work zone-related projects.”

Work Zone ITS Blog addressed the efforts of Matthew Daeda and Illinois DOT on May 12, 2016. We told you that this contracting method offers several advantages:

  1. The state only pays when the system is needed.
  2. They work directly with the vendor and that greatly improves communication.
  3. Staff has direct access to the system data and to make changes.
  4. By bidding for each district local companies are more likely to win, thus reducing response time.

 

This fact sheet is a BIG deal! States are always saying they don’t have the funding. This is one way of getting it. And the Feds aren’t just allowing this. They are encouraging states to use HSIP funds for work zone ITS.

States do need to identify work zone safety as a SHSP Focus Area and provide the data to support that decision. According to the National Work Zone Safety Information Clearinghouse, there were 799 fatalities in US work zones in 2017, up from the previous three-year average of 764. That’s not much when compared to the total roadway fatalities of 37,133.

But work zones are always a safety issue. States can and should include them in their Strategic Highway Safety Plans (SHSP) for a variety of reasons. Work zones force drivers to process more information and react faster than they normally do outside of work zones. That’s why crashes attributable to distracted driving, speeding, aggressive driving, and impaired driving often show up first in work zones. Furthermore, solutions that work in work zones may have applications elsewhere.

In 2017 overall fatalities declined nationally while work zone fatalities increased. Any state with this same disparity should include work zones in the SHSP. Many states have recently increased funding for road construction. They, too, will unfortunately see an associated increase in work zone fatalities. And, again, they to should include work zones in their SHSPs.

This is a wonderful tool. Thank you to Todd Peterson and Jawad Paracha for putting it together. Now we all just need to get his in front of the decision makers in our states!

 

Required Operator Training for Autonomous Vehicles?

We have talked here in the past about the difficulties autonomous vehicle drivers (operators?) will have acclimating when control of their vehicles is handed back to them, such as when they approach a work zone. Studies with simulators have shown a need for anywhere from 4 to 14 seconds for a driver to get a full grasp of all of the relevant external factors they must consider as they begin to drive.

A recent article in Axios Autonomous Vehicles points out that aviation has made use of automation for some time now. And they, too, understand the problem of moving from automated to human operators. In aviation, training focuses on that hand-off. Pilots are drilled in flight simulators on a variety of potential problems. So, when they encounter that problem during a real flight, muscle memory takes over and they react quickly and correctly.

The recent 737 Max 8 crash further underlines the importance of that training. It was apparently not included and that may have contributed to the pilot’s difficulty in regaining control.

The difference between aviation and autonomous vehicles is that training is mandatory for all pilots. If you fly a 767 you must stay current in all 767 training. However, for vehicles, a big selling point is that drivers no longer have to drive. They are told they can act more as passengers – gazing out the window, catching up on work, or watching an endless variety of streaming entertainment. Getting from that idea to one of mandatory training is a very long stretch!

Adding to the problem are the very different ways automakers are designing the machine-to-human hand-off. Each one is different.

In the Axios article, they quote Steve Casner of NASA, “We’re terrible at paying attention — and we think we’re awesome at it” Mr. Casner argues that drivers will need training. And they will need continuous updates to that training in order to learn how to deal with automation. Without initial user training and frequent refresh classes drivers will quickly become complacent.

This is a new topic of discussion but one that we must have to make CAVs safe for work zones and other segments of roadway with changing conditions.

Work Zone Traffic Control “Down-Under”

We just returned from a wonderful trip to Australia where we spoke to the Traffic Management Association of Australia (TMAA) about work zone ITS. Their members were all excited and focused on finding safer, more efficient ways to manage their work zones.

The program was packed full of interesting speakers and a variety of timely topics. They also gave us all just the right amount of time to discuss those topics between sessions. It was very well run.

The attendees seemed to enjoy talking to Americans and all asked what we thought of the meeting. My first answer was always the same: traffic control companies in both countries share the exact same set of problems:

1) Speeding in work zones.

2) End-of-queue crashes.

3) Hiring, training and retaining good employees.

4) A perception by the driving public that we are there to make their lives miserable.

5) Insufficient funding for maintenance and construction.

6) Changing standards and levels of enforcement from one state to the next.

7) Varying commitment and funding levels from one state to the next.

Just like ATSSA, the TMAA brings contractors, manufacturers, academia and government agencies together to discuss these problems and identify solutions. The TMAA does an especially good job of this. We look forward to learning more from them in the years to come!

Distracted Driving and Work Zones

We all know that distracted driving is resulting in increased fatalities on our roadways. The National Safety Council reported a 6% increase in fatalities in 2016. According to the National Work Zone Safety Information Clearinghouse, overall roadways fatalities increased 13% from 2013 to 2016. And during that same period, work zone fatalities increased 28%!

We enjoyed a period of dramatic decline in these numbers in the early 2000’s and then in 2013 they suddenly began to climb again. A small part of that change was due to improving economic activity and the increase in vehicle miles traveled that came as a result. But far more is due to other factors and distracted driving certainly tops the list.

The National Safety Council reports that 47% of drivers feel comfortable texting while they are driving. But we know that, in fact, texting while driving often increases reaction times more than driving under the influence.

But the problem is bigger than just that. In a recent article by Dr. Carl Marci, a neuroscientist writing in the January 4th issue of Perspectives magazine (http://www.nielsen.com/us/en/insights/news/2018/perspectives-driving-while-distracted-the-challenges-of-measuring-behavior-in-complex-environments.html), he said that our cars may be contributing to the distracted driving problem as well! This question occurred to him driving home one night so he ran a test using standard bio-metric equipment on a short drive on an unfamiliar road in Boston. The results showed the driver looked at his or her phone 60 times during a ten minute trip! A study by Zendrive reinforces these findings. They found that drivers use their phones for 88% of their trips.

Dr. Marci explains this by examining the way we use our phones outside of our vehicles. Any time we are bored, we look at our phone. Sitting at home in front of the TV, standing on a street corner waiting for a bus, or sitting in slow a meeting at work – we all check our phones when we get bored. And then we are often rewarded for doing so with a response from others. Email and social media have changed the way we act in very profound and far-reaching ways. And that can’t be turned off when we get behind the wheel.

Furthermore, our cars are becoming very comfortable. They resemble our living rooms more every day. Elaborate electronics help guide us to our destination, provide entertainment, and interface with our phones calling and communications applications.

We do use our cars electronics and phones for legitimate reasons while driving. They give us directions to our destination. They warn us of traffic problems along our planned route. They tell us of weather changes that may be important. So our phones & automotive electronics can help us get where we are going more safely. But once we use these for legitimate reasons, we can’t put them down. Or our drive becomes boring or our phone beeps to announce a new text, and we can’t seem to wait until we stop to check those messages.

So, back to work zones. A 28% increase in work zone fatalities cannot be ignored. Distracted driving is a growing and potentially catastrophic trend for work zones. Work zone ITS has always helped to reduce crashes. But this trend in distracted driving makes the use of work zone ITS all the more important. End of queue systems, dynamic merge systems, and variable speed limit systems can all get drivers attention, improve their work zone awareness, and help mitigate the effects of distracted driving. Let’s get ahead of this trend now before it gets any worse.
