    global ransom ware infection currently underway
    Another global ransom ware attack is currently underway.  Report started coming in about an hour ago from Europe.  This attacks seems to be from a evolved ransom ware virus with very similar characteristic to the WannaCry virus earlier this year.  If you recall, these new strain of virus does not require human clicking on a link.  These new virus are self propagating across older, networked, unpatched Windows operating systems.
    Additional details are in the Cyber security Discussion Forum.

    Free FHWA workshops on improving capabilities in six areas of TSMO
    FHWA has developed frameworks that focus on improvement actions for specific TSM&O program areas. These frameworks are designed for agencies and regions to assess the current strengths and weaknesses and to help develop a targeted action plan for the program area. The frameworks allow assessment of current agency capabilities in six areas of TSMO:
    Traffic ManagementPlanned Special EventsRoad Weather ManagementTraffic Incident ManagementTraffic Signal System ManagementWork Zone ManagementAgencies can use the tools available on the website to walk through the framework. An interactive online CMF tool is available for each of the six program areas at
    The frameworks are not intended to create benchmarks of an agency’s capabilities, but rather provide a resource for agencies to identify appropriate actions for improving TSMO. While periodic assessments are not required, revisiting the CMF online tool on a regular basis is recommended when significant organizational change occurs or prior to major investments.
    FHWA has the resources available to work with agencies to host a workshop for their agency or region. If you are interested in hosting a workshop, please contact the FHWA leads for this activity:

    Deep Machine Learning, Artificial Intelligence, Machine Vision and Transportation Innovation
    Image from the internet

    Artificial Intelligence, Deep Machine Learning, and Machine Vision are three main technologies leading human beings to the future. 
    In May 2017, AlphaGo, a narrow AI computer program developed by Alphabet Inc.'s Google DeepMind, played three Chinese traditional board games (WeiQi) with Ke Jie, the current world No.1 ranked player, and two exhibition games with several top Chinese professionals in Wuzhen. AlphaGo won all three games against Ke Jie. After winning its three-game match against Ke Jie, the world’s top Go player, AlphaGo is retiring. DeepMind is disbanding the team that worked on the game while continuing AI research in other areas. (Information from Wiki) 
    Prof Stephen Hawking, one of Britain's pre-eminent scientists, has said that efforts to create thinking machines pose a threat to our very existence. He told the BBC:"The development of full artificial intelligence could spell the end of the human race." His warning came in response to a question about a revamp of the technology he uses to communicate, which involves a basic form of AI. (Information from BBC) 
    Although the AI Takeover seems like ridiculous for now, but if we combine above two news together, it's not hard to imagine the future world. So in next few decades, these advanced technologies will become common into daily life. Just like the lighter and thinner laptop or tablet now comparing with the huge and slow Intel Pentium 4 PC 20 years ago.
    A technology boom will occur in next few decades, as well as the transportation innovation.
    Describe the future world in your mind or your thought about how these technologies relate to future transportation. Discuss with us and other experts in transportation and related domain.

    Older Windows OS are still vulnerable
    The WannaCry ransom ware targeting older Windows Operating system has been patched and it's unclear if the mitigation measures will still be effective.  
    This ransom ware is not the typical ransom ware where human assistance is required. WannaCry has attributes of a worm - a self propagating digital virus.  This is possible on the affected operating system due to a flaw.  This flaw in not present in newer Windows operating systems, and was one of the vulnerabilities revealed in the NSA tool leaks back in January.
    More details are in the cybersecurity discussion forum.

    Other ways to use high resolution data
    Clark County has installed 2070-1C CPU's with Trafficware firmware versions including high resolution data gathering at each of our intersections.  Each of these intersections communicates with our central system via high speed Ethernet.  We are in the process of establishing performance measures using the tools available in our ATMS system along with other information such as travel time from Bluetooth readers, permanent count stations etc.
    One comment that we receive is to the effect of "I waited forever for a green".  This is especially an issue if the citizen is driving late at night.  We have retrofitted all of our signals to include stopbar detection on all approaches so that during low volume times, we can program the signals for either short min greens on the main street, or in many cases, placing the main street into soft recall.  So when we receive a comment that someone waited a long time during the middle of the night, we want to know if this was real.
    The high resolution data can be mined for some information about delays on the side street.  The example below is for a signal that is at the exit from a County facility that includes a fueling station that the Sheriff's office uses during all hours.  One deputy called and complained that "the signal always takes forever to get out of the facility at 10:10 PM".  Now, from an engineer's, "forever" means a very long time - as in "forever".  I don't know how long the deputy thought he should wait, but it was worth looking into, especially since we have the data available, as long as we rethink some of the metrics that are in the Purdue coordination diagram.
    Here is a screen shot from our Purdue coordination diagram for a short period of time late at night from one of our signals.  The red circles show the northbound left, and the northbound thru / right lane stopbar detection actuation in relation to the beginning of the green.  This seems to indicate that there is a pretty snappy response from the signal.

    Here is the opposite approach (southbound stopbar detection) approaching the intersection at the same time and date.
    The red circles are where there was a detection and service.  The blue circles are where there was no detection, but there was a service.  The blue circles in this correspond to the northbound detection calling the phase.
    Note that one cycle did have a long wait, something on the order of 35 seconds or so at approximately 10:03 PM

    Here is the main street approach where both Eastbound and Westbound detection is shown, to attempt to see if there is a gap in the traffic causing the longer delay for the 10 PM car delay.

    Is there a problem here?  Maybe not.  It looks like there are cars on the main street (the black dots are both eastbound and westbound, so we don’t know how the gap out procedure is working in the controller when the one car had a long delay).
    We have looked at several instances where people report that they wait “forever” for “no cars at all on the main street”.  The high resolution data helps us understand what is happening.  Sometimes the citizen is right, sometimes, the data doesn’t support what the person is saying.  I choose not to argue with the citizen, but this helps us understand if there is a problem that we could help fix, or not.
    Here is another example where there was a problem we found by poking at the data.  The signal was in MAX recall on the main street, not min or soft recall, so it was holding with no cars.  It may be that we had a maintenance activity at this location, and the signal was placed in MAX recall for the maintenance, but not placed back into MIN recall.  Surprisingly, we heard about this from a citizen who went through late at night, and he contacted us on February 22.  We did a little digging, and found out he was correct.  We changed the main street to min recall yesterday afternoon, and he called the next day and was extremely happy that he could get through quickly now.

    Like I said, this isn’t the standard way of using the Purdue methodology, and I wouldn’t want to stake my reputation on it, but it is a nice way to see if maybe things that we hear from citizens are normal, or not.

    Funding Implementation of Automated Traffic Signal Performance Measures (ATSPMs)
    I frequently receive questions about grant programs and the eligibility of ATSPMs for federal funding and decided to post my typical response to share the information more broadly.  
    First, lets establish that ATSPMs are an improvement to traffic signal management and operations programs and are eligible for funding under the Federal-Aid Highway Program. Obtaining Federal-Aid funds requires working through the planning process, and yes a process is involved, but this is, in fact, the most sustainable approach to gaining and sustaining the long-term support that is needed to consistently provide funding to address the needs and objectives of the organization.  I would frame this approach as the adoption of an objectives and performance-based approach to managing and operating traffic signal systems.  For information about eligibility follow this link
    There are two Grant programs that have a number of agencies have used to successfully fund advanced traffic signal operations including adaptive control and ATSPMs:
    Fiscal year
    $60 M
    $60 M
    $60 M
    $60 M

  13. Mark Taylor added a post in a topic Automated Traffic Signal Performance Measures - Every Day Counts 4   

    So a few months ago, I was with one of my technicians in the field helping to troubleshoot a detection maxout problem that was still ongoing after several visits. While on site, I was reading through the history of the log book and came upon an entry dated August 22, 2016 at 15:50 that disturbed me. I took a picture of the entry (see below):.  It said, "Work order for phase 8 maxing out. Phase 8 running correctly. Sometimes maxing out on phases 2&6 &8 due to heavy traffic. Did observe phase 8 gapping out. Work order requires looking at phase 2&6 maxing out. Didn't see gapping out due to heavy traffic both directions. Checked advance sensors for north and south. Working great. Seeing vehicles 800 ft both directions. Re-visit maybe after dusk to see if phases 2&6 maxing out. Reset all matrix detection. Reset click 650. All working."  
    What I found disturbing was the fact that the technician said that they would MAYBE revisit after the PM peak when traffic dies down because traffic was too heavy at the time. I checked the rest of the logbook and this tech did not revisit the intersection after dusk like he said he may do. Anyhow, what bothered me more is all the work we have put into ATSPM's and this tech did not even check them as it would have told him right away the hours of the day of the  maxout problem (something that would take me 5 seconds to figure out).  I have attached the Purdue Phase Termination and you can see from the blue and red dots showing forceoffs and maxouts that the problem occurring well into the night and pretty much 24/7. 
    I fixed the problem while in the field (we had two BIU's talking to the same channel). I am embarrassed to say that this has been an issue since May 31 2016 and was not repaired until  December 20th. However, I used this example as a learning experience of always, always, always to check the ATSPM's before you respond on detector complaints as they will help know the severity of the problem and troubleshoot it much quicker than not using them. I also helped them understand that they don't need to visit the intersection at night or when traffic is light, as the ATSPM's will help them know the conditions then. 
    Use ATSPM's folks.  They will make your job easier but only if you use them.

    Automated Traffic Signal Performance Measures - Every Day Counts 4
    Automated Traffic Signal Performance Measures (ATSPMs) have been included in the FHWA Every Day Counts 4 Initiative.  Visit the EDC4/ATSPM website here to learn more 
    To view a recorded webinar that describes what ATSPMs are in the context of EDC4 and FHWA's approach to mainstreaming the use of ATSPMs nationally over the next two years follow this link  
    The NOCoE calendar of events will begin to be populated with upcoming workshops, presentations at professional meetings and webinars to keep you informed about what's happening with Automated Traffic Signal Performance Measures.  Stay tuned. 
    What is ATSPMs?
    Conceptually, ATSPMS are a suite of performance measures, data collection, and data analysis tools to support objectives and performance-based approach to managing the maintenance and operation activities of traffic signal programs.
    There are a number of approaches to implementing ATSPMs.  The approach selected for implementation should be consistent with the organizational capability of the agency.  For agencies with moderate to high capability a viable approach that is also cost-effective might be an open source alternative that can take advantage of existing infrastructure.  
    UDOT/ATSPM Approach - 
    Utah DOT developed and is currently sharing an application that was developed in house.  the UDOT Automated Traffic Signal Performance Measures (ATSPM) application is available for download here  The OSADP site has a discussion section if you have a question related to the installation or configuration of the UDOT/ATSPM application.
    Other Approaches
    There are a number of products and services available to support the implementation of ATSPMs. In the coming weeks, FWHA will issue a Request For Information (RFI) with a set of requirements for ATSPMs.  I will share that information to provide a preliminary list of products that meet the conceptual definition of ATSPMs.
    If you would like to discuss how ATSPMs are being used to support traffic signal management, operations, maintenance or design please post that information in this forum or start a new thread.

  20. ivanovn added a post in a topic Member Survey: Ideas for Improving the NOCoE Discussion Forums   

    Here are a couple of thoughts I have regarding NOCoE forums. 
    What do you think the role of the discussion forums should be within NOCoE and the website?Discussion forums are an excellent resource because they provide an opportunity for structured discussion and knowledge exchange, which serves well the mission of the center. However, achieving that goal can be challenging if the forums are not accessible, relevant, and properly moderated, especially given that most participants in these forums are volunteers. The end goal of the forums should be to provide valuable information and lead to more formal outputs (white papers, research and implementation opportunities, etc.) 
    Do you currently use the discussion forums regularly (i.e., at least once per month)?No. 
    If not, what are some of the biggest reasons for not participating?There are several reasons for me not using forums regularly:
    I tend to forget to check the forums for updates. If there was a way to receive an email with full text of each forum post (at least as a custom setting) then I would receive notifications that would draw me back to the site and the forum. Similarly, there are other knowledge sharing venues that do a better job of keeping me updates. For example, LinkedIn has a number of relevant groups that I am a member of and which lead similar discussions that get summarized or sent to my email. I tend to look at those first, before thinking of the NOCoE.If so, what are some of the biggest value-adds that you see with the current system?Focused and specialized on operations. No individual LinkedIn group encompasses the expertise available from members of this site. However, a combination of LinkedIn groups and notifications currently presents a strong competition to NOCoE website. 
    Do you feel that the ability to create new threads for the forum via email would significantly increase your level of participation?Yes. But more importantly seeing the threads in the email and being able to reply would be helpful. Is that capability already available and I just missed it?
    Are there specific things that can be done with the forums to better mesh with your existing workflow?Closer email integration.
    Are there certain discussion topics that you feel are current missing in the forums? Or conversely, are there certain existing topics that you don't feel are appropriate?I need to spend some more time on the forums to better answer this question.
    Keep up the good work!

    Regarding the question on truck climbing/passing lanes:
    We are aware of several instances of states allowing slow-moving trucks to use shoulders on long grades, but use is typically permitted at all hours of the day so it is not “part-time”

  22. JimHunt added a post in a topic NOCoE Part-Time Shoulder Use Webinar Q&A   

    Regarding question 6 on colored pavement, currently the MUTCD recognizes colored pavement in a couple of instances (e.g. Green for bike lanes and Red for bus lanes that are open to buses full time). There is no designated color for part time shoulder use and using any plan to use colored pavement would require a request to experiment.

  23. JimHunt added a post in a topic NOCoE Part-Time Shoulder Use Webinar Q&A   

    Regarding Question 5 on First Responders, there are a couple of facets to this issue:
    Collaboration with police and other emergency responders is fundamental to success.
    Emergency turn off areas should be installed, ideally every half mile or so.
    Under and ATM scenario, the ability to close the shoulder lane and merge traffic into the GP lanes could mitigate the response challenges.
    If all else fails, EM vehicles will split the traffic or in some cases may respond from the opposite direction.
    To the extent that part-time shoulder use smooths flow and crashes can be reduced, it might make things overall better from a response standpoint.

    NOCoE Part-Time Shoulder Use Webinar Q&A
    On July 14, 2016, the NOCoE hosted a Webinar on the practice of Part-Time Shoulder Use. The Webinar provided an overview of the recently published FHWA Part-Time Shoulder Use Guidebook, and peer state program examples from the Virginia  and Colorado DOT. The panelist for the webinar included the following:
    Jim Hunt, FHWA Office of OperationsPete Jenior, Kittelson & Associates, Inc.Dean Gustafson, VDOT, State Operations EngineerRyan Rice, CDOT, Director of the Division of TSM&OSan Lee, CDOT, TSM&O Programs and Policy ManagerThis discussion thread was started to help facilitate further questions and conversation on the information presented by the panelist. So far the following questions have been submitted:
    To All:  What is the most common criteria for activating dynamic shoulder use?To VDOT: Do you get a lot of vehicles riding in the shoulder lane when the red X is displaying on the dynamic sign?To CDOT: Was your I-70 traffic analysis only for Sunday, which was able to trigger the value in initiating project development?To All:Why has different pavement been discouraged if it seems to be advantageous?To All: Since First responders normally rely on the shoulder to expedite their access to traffic incidents, what accommodations might be made for them if a shoulder is not available because it is being used as a live traffic lane?To CDOT:  I understand the Hard SHoulder Running project was tied to a reversible lane. The improvement charts and figures that you should indicate improvement only for Hard SHoulder Running implementation or for that combined with the reversible lane?To All: Any guidance on use of shoulders as a truck passing or climbing lane, especially when traffic volumes and truck traffic percentages are high?
