btkuhn added a topic in General DiscussionFree FHWA workshops on improving capabilities in six areas of TSMOFHWA 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 http://www.ops.fhwa.dot.gov/tsmoframeworktool/index.htm.
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:

JasonS added a topic in General DiscussionDeep Machine Learning, Artificial Intelligence, Machine Vision and Transportation InnovationImage 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.

Ed added a topic in General DiscussionOlder Windows OS are still vulnerableThe 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.

Rob Klug added a topic in Traffic SignalsOther ways to use high resolution dataClark 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.

eddiejcurtis added a topic in Traffic SignalsAutomated Traffic Signal Performance Measures - Every Day Counts 4Automated 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 https://www.fhwa.dot.gov/innovation/everydaycounts/edc_4/atspm.cfm
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 https://connectdot.connectsolutions.com/p5w0i2mtnx8/?launcher=false&fcsContent=true&pbMode=normal
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 - http://udottraffic.utah.gov/atspm/
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 https://www.itsforge.net/index.php/community/explore-applications#/30/129. The OSADP site has a discussion section if you have a question related to the installation or configuration of the UDOT/ATSPM application.
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.

Brad Freeze added a topic in General DiscussionNOCoE Part-Time Shoulder Use Webinar Q&AOn 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?

slavrenz added a topic in General DiscussionMember Survey: Ideas for Improving the NOCoE Discussion ForumsAll,
NOCoE is in the midst of developing some changes to its discussion forums, in order to encourage greater participation from our membership. As part of this process, I would like to solicit feedback directly from the TSMO community, to further refine our development efforts and focus our resources. I would appreciate it if you would give some thought to the following questions:
What do you think the role of the discussion forums should be within NOCoE and the website?Do you currently use the discussion forums regularly (i.e., at least once per month)?If not, what are some of the biggest reasons for not participating?If so, what are some of the biggest value-adds that you see with the current system?Do you feel that the ability to create new threads for the forum via email would significantly increase your level of participation?Are there specific things that can be done with the forums to better mesh with your existing workflow?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?You can either post your responses/thoughts here, or email them to me directly at email@example.com. Thank you in advance for helping us to better engage the TSMO community!

Nathaniel.Price added a topic in Traffic Incident Management / Emergency Transportation OperationsTowing PolicyThe Oregon DOT and Oregon State Police are working on updating their Oregon Towing Laws. We are looking for states that might have recently gone through reforming their tow policies and laws. We are primarily looking for general tow regulations and policies, as opposed to heavy tow incentive programs. We are looking for best practices, lessons learned, etc. Also if you have a good contact at the State DOT or State Police that I could pass along to our TIM Coordinators at ODOT and OSP to follow up with them, that would be great.
